This is a collapsed lung caused by air in the pleural space.
- A.
Hemothorax
- B.
Asthma
- C.
Pneumonia
- D.
Apnea
- E.
Pneumothorax
Correct Answer
E. PneumothoraxExplanation
A pneumothorax refers to a collapsed lung caused by the presence of air in the pleural space. The pleural space is the area between the lung and the chest wall. When air enters this space, it disrupts the normal pressure balance and causes the lung to collapse. Symptoms of a pneumothorax may include sudden chest pain, shortness of breath, and decreased breath sounds on one side of the chest. Treatment for a pneumothorax may involve the removal of air from the pleural space and the use of a chest tube to re-expand the lung.Rate this question:

What is NOT true about Asthma?
- A.
It can be triggered by air temperature and allergens.
- B.
It is the inflammation of the throat.
- C.
It causes difficulty breathing.
- D.
It is the inflammation of the bronchi and bronchioles
Correct Answer
B. It is the inflammation of the throat.Explanation
Asthma is a chronic respiratory condition characterized by inflammation and narrowing of the airways. It is not the inflammation of the throat, as stated in the answer. Instead, it primarily affects the bronchi and bronchioles, leading to symptoms such as difficulty breathing and wheezing. Asthma can be triggered by various factors including air temperature, allergens, exercise, and respiratory infections. The inflammation in the airways causes them to become sensitive and react to these triggers, resulting in symptoms and breathing difficulties.Rate this question:

- B.
Send signals through the spinal cord and brain to tell other parts of the body what to do.
- C.
Take waste products and take them out of the body.
- D.
To allow gas exchange to provide parts of the body with oxygen.
Correct Answer
D. To allow gas exchange to provide parts of the body with oxygen.Explanation
The function of the respiratory system is to allow gas exchange, specifically providing parts of the body with oxygen. This is achieved through the process of breathing, where oxygen is inhaled and carbon dioxide is exhaled. The respiratory system includes organs such as the lungs, bronchi, and diaphragm, which work together to facilitate the exchange of gases between the air and the bloodstream. Oxygen is then transported to various parts of the body to support cellular respiration and provide energy for bodily functions.Rate this question:
-
- 4.
Where does the exchange of oxygen and carbon dioxide take place?
- A.
At the point where the trachea joins the lungs.
- B.
Within the alveoli.
- C.
Inside the right atrium of the heart.
- D.
Within the bronchi.
Correct Answer
B. Within the alveoli.Explanation
Each alveolus has a fine mesh of capillaries where the exchange of oxygen takes place. Blood containing carbon dioxide enters the capillaries lining the alveoli. The gas moves from the blood across a thin film of moisture and into the air sac. The carbon dioxide is then breathed out. On inhalation, oxygen is drawn into the alveoli, where it passes into the blood using the same film of moisture.Rate this question:

How do the lungs stay inflated?
- A.
Each lung is ribbed with cartilage to prevent collapse on exhalation
- B.
The lungs are tethered to the ribcage with a network of connective tissue.
- C.
The lungs rely on a vacuum within the chest, maintained by the diaphragm.
- D.
The lungs are made of muscular tissue that expands and contracts.
Correct Answer
C. The lungs rely on a vacuum within the chest, maintained by the diaphragm.Explanation
To stay inflated, the lungs rely on a vacuum within the chest. The diaphragm relaxes and contracts as we breathe. The change in air pressure ‘sucks’ air into the lungs on inhalation, and ‘pushes’ air out during exhalation.Rate this question:

The respiratory system is made up of trachea, the lungs, and the ___.
- A.
Liver.
- B.
Diaphragm.
- C.
Esophagus.
- D.
Pancreas.
Correct Answer
B. Diaphragm.Explanation
The respiratory system is responsible for the exchange of gases in the body. It includes organs such as the trachea, lungs, and diaphragm. The trachea carries air to and from the lungs, while the lungs are responsible for the actual exchange of oxygen and carbon dioxide. The diaphragm is a dome-shaped muscle located below the lungs that plays a crucial role in the process of breathing by contracting and relaxing to allow air to enter and leave the lungs. Therefore, the correct answer is the diaphragm.Rate this question:

When you breathe out, what gas does the body get rid of?
- A.
When you breathe out your body gets rid of nitrogen gas.
- B.
When you breathe out your body gets rid of carbon dioxide gas.
- C.
When you breathe out your body gets rid of oxygen gas.
- D.
When you breathe out your body gets rid of carbon monoxide gas.
Correct Answer
B. When you breathe out your body gets rid of carbon dioxide gas.Explanation
When you breathe out, your body gets rid of carbon dioxide gas. During respiration, your body takes in oxygen and releases carbon dioxide as a waste product. The oxygen is used by the cells in your body for various metabolic processes, and carbon dioxide is produced as a result. This carbon dioxide is then transported through the bloodstream to the lungs, where it is released when you exhale.Rate this question:

Which of the following is a passageway for air, food and water?
- A.
Pharynx
- B.
Larynx
- C.
Paranasal sinuses
- D.
Trachea
- E.
Esophagus
Correct Answer
A. PharynxExplanation
The pharynx is a passageway for air, food, and water. It is located behind the mouth and nasal cavity and connects to both the esophagus and the larynx. When we swallow, the epiglottis closes off the larynx to prevent food and water from entering the trachea. Therefore, the pharynx is responsible for directing air into the trachea and food and water into the esophagus.Rate this question:

This structure prevents food or water from entering the trachea.
- A.
Adenoids
- B.
Epiglottis
- C.
Nasopharynx
- D.
Thyroid cartilage
- E.
Uvula
Correct Answer
B. EpiglottisExplanation
The epiglottis is a flap of tissue located at the base of the tongue that prevents food or water from entering the trachea, also known as the windpipe. When we swallow, the epiglottis closes over the opening of the trachea, directing the food or liquid down the esophagus and into the stomach. This mechanism helps to prevent choking or aspiration of foreign substances into the respiratory system.Rate this question:
-
- 11.
This is located anterior to the esophagus and carries air to the bronchi.
- A.
Trachea
- B.

This is direction of diffusion of gases at capillaries near systemic cells.
- A.
Oxygen into blood , Carbon dioxide into blood
- B.
Oxygen out of blood , Carbon dioxide into blood
- C.
Oxygen into blood , Carbon dioxide out of blood
- D.
Oxygen out of blood , Carbon dioxide out of blood
Correct Answer
B. Oxygen out of blood , Carbon dioxide into bloodExplanation
The correct answer is Oxygen out of blood, Carbon dioxide into blood. This is because oxygen is transported from the blood into the systemic cells, while carbon dioxide is transported from the systemic cells into the blood. This process occurs through diffusion, where molecules move from an area of higher concentration to an area of lower concentration. In the capillaries near systemic cells, the concentration of oxygen is higher in the blood compared to the cells, so it diffuses out of the blood into the cells. On the other hand, the concentration of carbon dioxide is higher in the cells compared to the blood, so it diffuses from the cells into the blood.Rate this question:
-
- 13.
This is direction of diffusion of gases at the alveoli of the lungs.
- A.
Oxygen into blood , Carbon dioxide into blood
- B.
Oxygen out of blood , Carbon dioxide into blood
- C.
Oxygen into blood , Carbon dioxide out of blood
- D.
Oxygen out of blood , Carbon dioxide out of blood
Correct Answer
C. Oxygen into blood , Carbon dioxide out of bloodExplanation
The correct answer is "Oxygen into blood, Carbon dioxide out of blood." This is because during respiration, oxygen from the alveoli diffuses into the bloodstream, where it binds to hemoglobin in red blood cells. At the same time, carbon dioxide, which is a waste product of cellular respiration, diffuses out of the bloodstream into the alveoli to be exhaled. This process allows for the exchange of gases between the lungs and the bloodstream, ensuring that oxygen is delivered to the body's tissues and carbon dioxide is removed.Rate this question:

As you breathe, this muscle contracts and flattens to give your lungs room to fill up with air ___.
- A.
Larynx
- B.
Lung lobes
- C.
Diaphragm
- D.
Bronchiole
Correct Answer
C. DiaphragmExplanation
The diaphragm is a dome-shaped muscle located below the lungs. When you breathe in, the diaphragm contracts and flattens, creating more space in the chest cavity. This allows the lungs to expand and fill up with air. When you breathe out, the diaphragm relaxes and returns to its dome shape, pushing air out of the lungs. Therefore, the diaphragm plays a crucial role in the process of breathing by helping to regulate the movement of air in and out of the lungs.Rate this question:

What muscle group allows you to breathe in and out?
- A.
The lungs
- B.
The trachea
- C.
The nares
- D.
The diaphragm
Correct Answer
D. The diaphragmExplanation
The diaphragm is a muscle group that allows you to breathe in and out. It is located at the base of the lungs and separates the chest cavity from the abdominal cavity. When it contracts, it flattens and moves downward, increasing the space in the chest cavity and allowing the lungs to expand and fill with air. When it relaxes, it moves back up, decreasing the space in the chest cavity and helping to expel air from the lungs. Therefore, the diaphragm plays a crucial role in the process of breathing.Rate this question:
