Introduction to Lung Physiology
Multiple Choice
In the context of lung physiology, which body system primarily removes carbon dioxide (CO2) from the blood?
A
Skeletal system
B
Respiratory system
C
Digestive system
D
Integumentary system
검증된 단계별 안내1
Understand the role of each body system listed: the skeletal system supports the body structurally, the digestive system processes food, and the integumentary system protects the body and regulates temperature.
Recall that carbon dioxide (CO2) is a waste product of cellular respiration that must be removed from the blood to maintain homeostasis.
Identify that the respiratory system is responsible for gas exchange, specifically taking in oxygen and expelling carbon dioxide through the lungs.
Recognize that CO2 is transported in the blood to the lungs, where it diffuses from the blood into the alveoli and is then exhaled.
Conclude that the respiratory system is the primary system that removes carbon dioxide from the blood, distinguishing it from the other systems listed.
