In introductory lung physiology, what is the main function of the respiratory system?
A
To produce hormones that regulate blood glucose and metabolism
B
To exchange gases by delivering oxygen to the blood and removing carbon dioxide from the blood
C
To filter metabolic wastes from plasma and regulate blood volume
D
To pump blood through systemic and pulmonary circuits
Verified step by step guidance1
Identify the primary role of the respiratory system by recalling its main physiological function in the body.
Understand that the respiratory system is responsible for gas exchange, which involves taking in oxygen and removing carbon dioxide.
Recognize that other options such as hormone production, waste filtration, and pumping blood are functions of different systems (endocrine, urinary, and cardiovascular systems respectively).
Focus on the process of oxygen delivery to the blood and carbon dioxide removal from the blood as the key function of the respiratory system.
Conclude that the main function of the respiratory system is to exchange gases by delivering oxygen to the blood and removing carbon dioxide from the blood.
