Which of the following is the primary function of the respiratory system?
A
To exchange gases between the body and the environment
B
To transport nutrients throughout the body
C
To protect the body from pathogens
D
To produce hormones that regulate metabolism
Verified step by step guidance1
Begin by identifying the main components of the respiratory system, which include the lungs, trachea, bronchi, and diaphragm.
Understand the primary role of the respiratory system, which is to facilitate the exchange of gases, specifically oxygen and carbon dioxide, between the body and the environment.
Consider the process of inhalation and exhalation, where oxygen is brought into the lungs and carbon dioxide is expelled, highlighting the gas exchange function.
Differentiate the respiratory system's function from other systems, such as the circulatory system, which transports nutrients, and the immune system, which protects against pathogens.
Recognize that hormone production and regulation of metabolism are functions of the endocrine system, not the respiratory system.
