What are Bronchioles?

Subdivisions of bronchi
Part of the trachea
Where gas exchanges happen
Cartilages of the larynx
Parts of the diaphragm

Correct Answer

A. Subdivisions of bronchi

Explanation

Bronchioles are small airways in the lungs that branch off from the bronchi. They are responsible for further dividing the air passages and delivering air to the alveoli, where gas exchanges occur. The bronchioles do not belong to the trachea, larynx, or diaphragm, but are instead subdivisions of the bronchi.

It is located from the mouth until the

Correct Answer
lungs

Explanation
The given answer states that "It is located from the mouth until the lungs." Based on the context provided, it can be inferred that the answer is referring to the respiratory system or the pathway of air. Air enters the body through the mouth and travels down the throat, through the trachea, and finally reaches the lungs where the process of respiration takes place. Therefore, the answer is suggesting that the location of the described pathway is from the mouth until the lungs.

What internal respiration serves for?

Generate Carbon Dioxide
Generate Carbon Monoxide
Generate ATP
Generate nails
Generate the trachea

Correct Answer

A. Generate ATP

Explanation

Internal respiration serves to generate ATP. ATP is the main energy currency of the cell and is required for various cellular processes. During internal respiration, oxygen is delivered to the cells and used in the process of cellular respiration to produce ATP. This occurs in the mitochondria of the cells, where glucose and oxygen are metabolized to produce ATP through a series of chemical reactions. Therefore, internal respiration is essential for providing the necessary energy for cellular activities.

What is the normal number of breaths per minute?

12 to 16 with 2 seconds separation
30 to 35 with 4 seconds separation
10 to 18 with 2 seconds separation
5 to 8 with 5 seconds separation
10 to 18 with 4 seconds separation

Correct Answer

A. 10 to 18 with 2 seconds separation

Explanation

The normal number of breaths per minute is typically between 10 to 18 with a 2-second separation. This range is considered normal for a healthy adult at rest. The 2-second separation refers to the duration between each breath.

The respiratory system is a part of the

Correct Answer
autonomic nervous system

Explanation
The autonomic nervous system is responsible for controlling involuntary bodily functions, including the respiratory system. The respiratory system consists of organs and tissues involved in the exchange of gases, such as the lungs and diaphragm. These organs are regulated by the autonomic nervous system, which controls breathing rate and depth based on the body's needs. Therefore, it is correct to say that the respiratory system is a part of the autonomic nervous system.

The acessory muscles of the respiratory system are

Correct Answer
they are sternocledomastoid, platysma and scalene muscles of the neck

Explanation
The accessory muscles of the respiratory system are the sternocleidomastoid, platysma, and scalene muscles of the neck. These muscles are not directly involved in the normal breathing process but are recruited during times of increased respiratory demand or when the primary breathing muscles are compromised. The sternocleidomastoid muscle helps elevate the sternum and rib cage during deep inhalation, while the platysma muscle assists in elevating the hyoid bone and opening the airway. The scalene muscles aid in elevating the upper ribs and expanding the chest cavity during forced inhalation.
