The primary function of the respiratory system is _________

Correct Answer
respiration

Explanation
The primary function of the respiratory system is respiration. Respiration refers to the process of inhaling oxygen and exhaling carbon dioxide. The respiratory system is responsible for facilitating this exchange of gases between the body and the environment. It includes organs such as the lungs, trachea, bronchi, and diaphragm, which work together to ensure the proper intake of oxygen and removal of carbon dioxide. Without respiration, the body would not be able to obtain the necessary oxygen for cellular respiration and energy production.

Rate this question:
6.

In the process of respiration our bodies take in ______ and release _______. (_______, ________)

Correct Answer
oxygen, carbon dioxide
O2, CO2

Explanation
During respiration, our bodies take in oxygen and release carbon dioxide. Oxygen is necessary for the process of cellular respiration, where it is used to break down glucose and produce energy in the form of ATP. Carbon dioxide is a waste product of this process and is expelled from the body through the respiratory system. The symbols O2 and CO2 represent oxygen and carbon dioxide, respectively.

Rate this question:
7.

What are the two main processes of respiration? (________,_________)

Correct Answer
ventilation, gas exchange
gas exchange, ventilation

Explanation
The two main processes of respiration are ventilation and gas exchange. Ventilation refers to the movement of air in and out of the lungs, while gas exchange is the process by which oxygen is taken in and carbon dioxide is expelled from the body. These two processes work together to ensure that the body receives an adequate supply of oxygen and gets rid of waste carbon dioxide.

Breathing is regulated by the _______ and __________. (_______, _________)

Correct Answer
pons, medulla oblongata
medulla oblongata, pons

Explanation
The correct answer is pons, medulla oblongata. The pons and medulla oblongata are both parts of the brainstem, which is responsible for regulating many automatic functions of the body, including breathing. The pons helps to control the rate and depth of breathing, while the medulla oblongata is responsible for coordinating the muscles involved in the breathing process. Together, these two structures work to ensure that the body receives the oxygen it needs and removes carbon dioxide efficiently.

___________ works to increase a disruptive influence and produce a permanent change.
- Negative feedback
- Positive feedback
Correct Answer

A. Positive feedback

Explanation

Positive feedback works to increase a disruptive influence and produce a permanent change. Unlike negative feedback, which works to counteract or reduce a disruptive influence and restore equilibrium, positive feedback amplifies the initial disturbance, leading to a self-reinforcing cycle that can result in a significant and lasting transformation. This can be seen in various natural and social systems, where positive feedback loops can lead to exponential growth or cascading effects, ultimately causing a permanent shift in the system's behavior or state.

The difference between the functions of the endocrine and the nervous system is that endocrine signals activate more ________ than nervous signals, but they last _________.
- Quickly; shorter
- Slowly; longer
- Steadily; longer
- None of the above
Correct Answer

A. Slowly; longer

Explanation

The correct answer is "slowly; longer". The endocrine system uses hormones to send signals throughout the body, and these signals take time to travel through the bloodstream and have an effect on target cells. In contrast, the nervous system uses electrical impulses to send signals, which can travel quickly along nerve cells. However, these signals are usually short-lived and have a more immediate impact. Therefore, endocrine signals activate more slowly but have a longer-lasting effect compared to nervous signals.

11.

Hypothalamus --> pituitary g. --> other glands is the most common way we control hormones.
- True
- False
Correct Answer

A. True

Explanation

The statement is true because the hypothalamus, which is a part of the brain, controls the pituitary gland, which in turn controls the other glands in the body. The hypothalamus releases hormones that stimulate or inhibit the release of hormones from the pituitary gland. The pituitary gland then releases hormones that regulate the activity of other glands, such as the thyroid gland, adrenal glands, and reproductive glands. This pathway is known as the hypothalamic-pituitary axis and is responsible for maintaining hormonal balance in the body.

Rate this question:
12.

________ Hormones activate receptors on the membrane, causing certain proteins to turn on or off.
- Steroid
- Non-steroid
Correct Answer

A. Non-steroid

Explanation

Non-steroid hormones activate receptors on the membrane, which means they bind to receptors located on the cell membrane. This binding triggers a signaling cascade that ultimately leads to the activation or inhibition of certain proteins within the cell. In contrast, steroid hormones are able to pass through the cell membrane and bind to receptors inside the cell, directly affecting gene expression. Therefore, the statement aligns with the characteristics of non-steroid hormones.

Rate this question:
13.

A hormones that goes from one gland to another gland
- Tropic hormones
- Osmoreceptors
- Tropical hormones
- None of the above
Correct Answer

A. Tropic hormones

Explanation

Tropic hormones are hormones that are released by one gland and act on another gland. They regulate the secretion of hormones from the target gland, thereby controlling various physiological processes in the body. This communication between glands is essential for maintaining hormonal balance and ensuring proper functioning of the endocrine system. Therefore, tropic hormones are the correct answer as they fit the description of hormones that go from one gland to another gland.

The accessory organs are part of the respiratory system, made up of the diaphragm and intercostal muscles
- True
- False
Correct Answer

A. True

Explanation

The given statement is true. The accessory organs mentioned, the diaphragm and intercostal muscles, are indeed part of the respiratory system. The diaphragm is a dome-shaped muscle located at the base of the lungs, and it plays a crucial role in the process of breathing by contracting and relaxing. The intercostal muscles are located between the ribs and help in expanding and contracting the chest cavity during breathing. These organs work together with the lungs to facilitate the inhalation and exhalation of air, making them integral parts of the respiratory system.

17.

______ works against a change/disruption in order to maintain homeostasis.
- Positive feedback
- Negative feedback
Correct Answer

A. Negative feedback

Explanation

Negative feedback works against a change/disruption in order to maintain homeostasis. This means that when there is a deviation from the desired state or set point, negative feedback mechanisms are activated to bring the system back to its original state. For example, in temperature regulation, if the body temperature rises above the set point, negative feedback mechanisms such as sweating and vasodilation are activated to cool down the body and bring the temperature back to normal.

Rate this question:
18.

Like the nervous system, the endocrine system is responsible for CONTROLLING the functions of other body systems.
- True
- False
Correct Answer

A. True

Explanation

The explanation for the given correct answer is that the endocrine system, like the nervous system, plays a crucial role in controlling the functions of other body systems. The endocrine system consists of glands that produce hormones, which are chemical messengers that regulate various bodily functions. These hormones are released into the bloodstream and travel to target organs or tissues, where they exert their effects and help maintain homeostasis. Therefore, it is true that the endocrine system is responsible for controlling the functions of other body systems.

Rate this question:
19.

_______ Hormones enter cells, modify DNA, and control protein production
- Steroid
- Non-steroid
Correct Answer

A. Steroid

Explanation

Steroid hormones are able to enter cells because they are lipid-soluble, allowing them to pass through the cell membrane. Once inside the cell, they bind to specific receptors in the nucleus, where they modify DNA by activating or inhibiting certain genes. This modification of DNA then leads to the regulation of protein production, allowing steroid hormones to control various cellular processes and physiological functions. Non-steroid hormones, on the other hand, cannot enter cells and instead bind to receptors on the cell surface, triggering a signaling cascade that ultimately affects protein production.

In ventilation (inspiration) when the ________ and _________ muscles contract, the thoracic cavity expands and the pressure in the lungs decreases pulling in air.
- Sternum, intercostals
- Diaphragm, intercostals
- Diaphram, thoracic cavity
- None of the above
Correct Answer

A. Diaphragm, intercostals

Explanation

When the diaphragm and intercostal muscles contract during inspiration, the thoracic cavity expands. This expansion creates a decrease in pressure within the lungs, causing air to be pulled into the lungs. The diaphragm is a dome-shaped muscle located at the base of the lungs, and when it contracts, it moves downward, increasing the volume of the thoracic cavity. The intercostal muscles are located between the ribs, and when they contract, they lift the ribcage, further expanding the thoracic cavity. Therefore, the correct answer is diaphragm, intercostals.

Rate this question:
22.

Ventilation (expiration): when breathing muscles relax, ________ of the lungs, thoracic wall, and abdominal organs push in on the thoracic cavity
- Elastic recoil
- Slinky
- Plastic recoil
- None of the above
Correct Answer

A. Elastic recoil

Explanation

When the breathing muscles relax during expiration, the elastic recoil of the lungs, thoracic wall, and abdominal organs push in on the thoracic cavity. This elastic recoil is a natural property of the lungs and other surrounding structures, allowing them to return to their original shape and size after being stretched during inhalation. This recoil helps to decrease the volume of the thoracic cavity, which increases the pressure inside the lungs and causes air to be expelled. The other options (slinky and plastic recoil) are not relevant to the process of ventilation and do not accurately explain the phenomenon described in the question.

Rate this question:
23.

_________ gets messages from the hypothalamus and makes brand new hormones in response to those messages.
- Anterior pituitary
- Posterior pituitary
Correct Answer

A. Anterior pituitary

Explanation

The anterior pituitary gets messages from the hypothalamus and produces new hormones in response to those messages. The hypothalamus sends releasing and inhibiting hormones to the anterior pituitary, which then stimulates the production and release of various hormones that regulate growth, reproduction, metabolism, and other bodily functions. The posterior pituitary, on the other hand, does not produce hormones but rather stores and releases hormones that are produced by the hypothalamus. Therefore, the correct answer is the anterior pituitary.

Rate this question:
24.

What gland needs iodine to function properly?
- Thyroid gland
- Posterior pituitary gland
- Hypothalamus gland
- Parathyroid gland
Correct Answer

A. Thyroid gland

Explanation

The term for concentration of gas is ______
- Atmospheric pressure
- Concentration
- Half pressure
- Partial pressure
- None of the above
Correct Answer

A. Partial pressure

Explanation

Partial pressure is the term used to describe the concentration of a gas in a mixture. It is the pressure that the gas would exert if it occupied the same volume alone at the same temperature. This concept is important in understanding gas behavior, especially in gas laws and in determining the movement of gases in and out of solutions or across membranes. Atmospheric pressure refers to the pressure exerted by the Earth's atmosphere, while concentration refers to the amount of a substance present in a given volume. Half pressure is not a recognized term in this context. Therefore, the correct answer is partial pressure.

In ventilation (inspiration) when the air pressure in the lungs is _____ than the atmospheric pressure, air will enter the lungs.
- Less
- More
- Equal
- None of the above
Correct Answer

A. Less

Explanation

During inspiration in ventilation, the diaphragm and intercostal muscles contract, causing the volume of the lungs to increase. This increase in volume leads to a decrease in air pressure within the lungs. As a result, the air pressure inside the lungs becomes lower than the atmospheric pressure, creating a pressure gradient that allows air to flow into the lungs. Therefore, the correct answer is "less."

Rate this question:
29.

Chemoreceptors detect high concentrations of carbon dioxide and hydrogen ions in the blood, and trigger inspiration
- True
- False
Correct Answer

A. True

Explanation

Chemoreceptors are sensory cells that detect changes in chemical composition, specifically high concentrations of carbon dioxide and hydrogen ions in the blood. When these chemoreceptors detect high levels of carbon dioxide and hydrogen ions, they send signals to the respiratory centers in the brain, which then trigger the process of inspiration or inhalation. Therefore, the statement that chemoreceptors detect high concentrations of carbon dioxide and hydrogen ions in the blood and trigger inspiration is true.

Chemical receptors that detect what's going on in your blood
- Chemoreceptors
- Osmoreceptors
- Tropic hormones
- Hypothalamus
Correct Answer

A. Osmoreceptors

Explanation

Osmoreceptors are chemical receptors that detect changes in the osmolarity (concentration) of the blood. They are responsible for monitoring the body's water balance and triggering the release of antidiuretic hormone (ADH) when the blood becomes too concentrated. This helps to regulate the body's fluid levels and maintain homeostasis. Osmoreceptors are primarily located in the hypothalamus, which is a region of the brain that plays a key role in regulating various bodily functions.

Rate this question:
34.

The accessory organs provide mechanical force that drives ventilation
- True
- False
Correct Answer

A. True

Explanation

The accessory organs, such as the diaphragm and intercostal muscles, play a crucial role in the process of ventilation. They contract and relax to create changes in the volume of the thoracic cavity, which leads to inhalation and exhalation. The diaphragm, when it contracts, moves downward and increases the volume of the thoracic cavity, allowing air to be drawn into the lungs. The intercostal muscles, on the other hand, help in expanding and contracting the ribcage, further aiding in the process of ventilation. Therefore, it is true that the accessory organs provide the mechanical force necessary for ventilation.

Rate this question:
35.

Ventilation (inspiration): _________ is the force that moves air into the lungs
- Absolute pressure
- Atmospheric pressure
- Air pressure
- Sinus pressure
Correct Answer

A. Atmospheric pressure

Explanation

Ventilation, specifically inspiration, is the process of moving air into the lungs. This movement is facilitated by the force of atmospheric pressure, which is the pressure exerted by the Earth's atmosphere. As the diaphragm contracts and the chest cavity expands, the pressure inside the lungs decreases, causing air to flow from an area of higher pressure (atmosphere) to an area of lower pressure (lungs). Therefore, atmospheric pressure is the force that moves air into the lungs during ventilation.

Rate this question:
36.

Ventilation (expiration): this raises the air pressure in the lungs, and air is forced out _____________.
- Deeply
- Passively
- Aggressively
- None of the above
Correct Answer

A. Passively

Explanation

During expiration, the diaphragm relaxes and moves upward, causing the air pressure in the lungs to increase. This increased pressure forces the air out of the lungs passively, without any active effort or force. Therefore, the correct answer is "passively".

Rate this question:
37.

Acute Affects: euphoria, relaxation altered perceptions, increased appetite, impaired memory, anxiety/paranoia
- Hallucinogens
- Depressants
- Cannabinoids
- Stimulants
Correct Answer

A. Cannabinoids

Explanation

The given symptoms of euphoria, relaxation, altered perceptions, increased appetite, impaired memory, anxiety/paranoia are commonly associated with the use of cannabinoids. Cannabinoids are a class of psychoactive substances that include marijuana and hashish. These substances interact with the cannabinoid receptors in the brain, leading to the observed effects. Hallucinogens, depressants, and stimulants can also produce altered perceptions and mood changes, but the combination of symptoms mentioned in the question is most closely associated with cannabinoids.

Ventilation: in forceful expiration, the _________ and the _________ contract and actively force air out of the lungs.
- Posterior intercostals and abdominal muscles
- Sternocleidomastoid and perctoralis minor
- Posterior intercostals and pectoralis major
- None of the above
Correct Answer

A. Posterior intercostals and abdominal muscles

Explanation

In forceful expiration, the posterior intercostals and abdominal muscles contract and actively force air out of the lungs. The posterior intercostals are responsible for pulling the ribs downward and inward, reducing the volume of the thoracic cavity. The abdominal muscles, including the rectus abdominis, external obliques, and internal obliques, contract to increase intra-abdominal pressure, pushing the diaphragm upward and further compressing the thoracic cavity. This combined action of the posterior intercostals and abdominal muscles creates a forceful contraction that helps expel air from the lungs.

Rate this question:
39.

You breathe air in because your lungs get bigger
- True
- False
Correct Answer

A. True

Explanation

When you breathe in, your diaphragm and intercostal muscles contract, causing your lungs to expand. This expansion creates a negative pressure inside the lungs, allowing air to rush in and fill the increased space. Therefore, it is true that your lungs get bigger when you breathe in air.

Rate this question:

Which is a part of the body shared by the respiratory and digestive tract?
- Larynx
- Pharynx
- Glottis
- Epiglottis
- Trachea
- None of the above
Correct Answer

A. Pharynx

Explanation

The pharynx is a part of the body that is shared by both the respiratory and digestive tracts. It is a muscular tube located behind the nasal cavity, mouth, and larynx. It serves as a passageway for both air and food. When we swallow, the epiglottis, a flap of tissue located at the top of the larynx, closes off the trachea to prevent food from entering the lungs. Therefore, the pharynx is the correct answer as it connects both the respiratory and digestive systems.

- Trachea and sternum
- Sternocleidomastoid and pectoralis minor
- Pectoralis minor and pectoralis major
- None of the above
Correct Answer

A. Sternocleidomastoid and pectoralis minor

Explanation

During deeper inspiration, in addition to the diaphragm and intercostal muscles, the sternocleidomastoid and pectoralis minor muscles also contract to expand the ribcage. This further increases the thoracic cavity volume and decreases the pressure in the lungs, allowing more air to be pulled in. The trachea and sternum are not directly involved in the expansion of the ribcage during inspiration. Therefore, the correct answer is sternocleidomastoid and pectoralis minor.

Rate this question:
43.

- Posterior intercostals and sternocleidomastoid
- Posterior intercostals and abdominal muscles
- Diaphragm and abdominal muscles
- None of the above
Correct Answer

A. Posterior intercostals and abdominal muscles

Explanation

During forceful expiration, the posterior intercostal muscles contract and pull the ribs downward, reducing the volume of the thoracic cavity. At the same time, the abdominal muscles contract, pushing the abdominal organs upward against the diaphragm. This combination of actions actively forces air out of the lungs, increasing the effectiveness of expiration. Therefore, the correct answer is posterior intercostals and abdominal muscles.
