Respiratory System Quizzes Online & Trivia

Pulmonary surfactant is a surface-active lipoprotein complex formed by type II alveolar cells. The proteins and lipids that make up the surfactant have both hydrophilic and hydrophobic regions. Hydrophilic means they mix. Hydrophobic means they don't. The surfactant absorbs into the air. The function of the surfactant is to increase pulmonary compliance, to prevent the collapse of the lung, and to enable employment of collapsed airways. Alveoli can be likened to gas in water, as the alveoli are wet and surrounded by a central air space. The surface tension acts in the air. The gas pressure is needed to keep an equilibrium.

Cor pulmonaleis defined as an alteration in the structure and function of the right ventricle (RV) of the heart caused by a primary disorder of the respiratory system.

In fact , larynx lies between pharynx and teachea , so the answer can also be larynxLarynx

The voice box is also known as the larynx. This is a tube that is about five centimeters long in adults. The size may be different for kids. This is located above the trachea and one of its main functions is to make sure that food will not get into the air passageway. Have you ever experienced eating and letting the food go down the wrong tube? You may feel a burning pain every time this happens. The pain will seize but this can be an issue if this happens often. The larynx is also responsible for the regulation of people’s voice pitch and the volume of the voice. The larynx is obviously one of the most important parts of the respiratory system.

The correct answer to this question is the larynx. It is an organ at the top of the neck. It is called the voicebox because it is what produces sound. The larynx is home to the vocal folds and it controls the volume and pitch of the sound. The larynx also has other functions, which include helping with breathing and protects against food aspiration occurring in the trachea. It is triangular in shape. There are two folds of the larynx. The top fold is vestibular folds. They are also known as false vocal folds, for they have no impact on sound. The bottom fold is called the vocal fold.

Alveoli are small air sacs in the lungs where many capillaries exchange carbon dioxide for oxygen taken into the body. They are the basic unit of ventilation. Alveoli are found in the respiratory zones of the lungs. They are located after the alveoli ducts and alveolar sacs. The gas exchange surface is the alveolar membrane. The capillaries are wrapped around each alveolus, creating a mesh appearance. Deoxygenated blood, which is rich in carbon dioxide from the body is pumped through the capillaries of the alveoli, and through diffusion, there is an exchange of gases (oxygen diffuse to the blood and carbon dioxide to the alveoli).

The sinuses are composed of small spaces which sit inside the human and animal skull. They help regulate the temperature and humidity of air taken into the body. The larger sinus cavities are about one inch across, but the smaller ones are more complex. The sinuses are lined with pink tissue called mucosa and typically, the sinuses are empty except for a thin layer of mucus. There are structures within the sinuses which help to filter the air within them. In anatomy, the word sinus is used to refer to a system of hollow cavities, and they are most important for health and comfort.

The diaphragm is the primary muscle used in respiration during the process of breathing. It is a thin, skeletal muscle that sits at the base of the chest. It contracts and flattens when you inhale, which creates a vacuum effect that pulls air into the lungs. When you exhale, the diaphragm relaxes as it is removed back into the lungs. The membrane also increases abdominal pressure to allow the body to expel vomit, urine, and feces, and the muscle also helps to prevent acid reflux. The diaphragm also comes with first openings which allow specific structures to pass between the chest and the abdomen. These openings include the esophageal opening, which helps with digestion, aortic opening to transport blood from the heart, and the caval opportunity to carry blood to the heart.

I think Annie is right this time john because the Trachea is the windpipe pipe and the Larynx does allows air to the lungs, but it probably is the larynx you never ever know ,but you probably will know if you just take a science class and study the stuff about this stuff it is really good stuff though for real.

1. use diaphragmatic breathing.-rationale: in chronic bronchitis the diaphragm is flat and weak. diaphragmatic breathing helps to strengthen the diaphragm and maximizes ventilation. exhalation should be longer than inhalation to prevent collapse of the bronchioles. the client with chronic bronchitis should exhale through pursed lips to prolong exhalation, keep the bronchioles from collapsing, and prevent air trapping. diaphragmatic breathing not chest breathing increases lung expansion. client needs category: physiological integrity client needs subcategory: reduction of risk potential cognitive level: application reference: smeltzer, s.c., et al. brunner & suddarths textbook of medical-surgical nursing,11th ed. philadelphia: lippincott williams & wilkins, 2008, p. 494.

The answer to this question is A. The respiratory system is in charge of the gas exchange between the external environment and the body’s circulatory system. The respiratory system is composed of different organs but the primary organs are the lungs. The lungs are in charge of making the exchange of gases possible. It gets oxygen that is spread throughout the body. In return, carbon dioxide is removed from the body. The carbon dioxide will be useful to living things that are responsible for producing oxygen namely the trees and plants. This explains why people need to be surrounded by more trees. They are in charge of providing the air we need to live for free.

The right bronchiole is located in letter G. You are aware that the lungs are highly important in making you breathe and live but have you ever paid any attention to the different parts of the lungs? One of the parts that you should pay attention to is the bronchiole. The bronchiole is known to be a branch that can be found in the lungs. This will serve as the passageway for air to pass through. The main purpose of this part is to make sure that the alveolus will get the right amount of oxygen that it needs. If the alveolus does not get enough oxygen, this may cause the small capillaries in the lungs to burst.
