Respiratory System Anatomy and Physiology
The System is the body system in which gas exchange takes place.
Write the letter (A - K) that corresponds with each structure of the respiratory system.
What is the main function of the nose?
- to exchange oxygen with carbon dioxide
- to warm and moisten the air entering the body
- to create the force that causes inspiration
- to initiate blood flow to the lungs for gas exchange
What part of the brain is considered the control center for breathing?
- the cerebrum
- the cerebellum
- the frontal lobe
- the medulla oblongata
What is the function of the pharynx?
- The pharynx serves as the passage between the mouth and the trachea.
- The pharynx is the specific location where gas exchanges in the lungs.
- The pharynx keeps foreign particles from entering the respiratory system.
- The pharynx is essential for maintaining proper concentrations of gases within the blood.
The instrument used by doctors to measure the volume of air exchanged while breathing is called a(n) .
What is the tidal volume in reference to breathing?
- Tidal volume is the amount of air left in the lungs after a forced exhalation.
- Tidal volume is the amount of air that is exchanged during a normal inhalation and expiration.
- Tidal volume is the maximum amount of air that can be forces into the lungs at any given time.
- Tidal volume is the amount of air that can be taken in during a normal inspiration.
Which molecule is an essential part of the process of gas exchange within the lungs?
How is Boyle's Law related to the process of breathing?
is a common disorder of the respiratory system that is characterized by recurring inflammation of the bronchi, making it very hard to breathe.
