Question

the respiratory system should remove which of the following from your body?
a. carbon monoxide
b. carbon dioxide
c. oxygen
d. oxygen bioxide

please select the best answer from the choices provided.

○ a
○ b
○ c
○ d

Explanation:

The respiratory system's main function in gas exchange is to take in oxygen and expel carbon dioxide, a waste product of cellular respiration. Carbon monoxide is a toxic gas not normally removed as a primary waste (A is incorrect). Oxygen is taken in, not removed (C is incorrect). "Oxygen bioxide" is not a valid chemical compound (D is incorrect). So the correct answer is the option related to carbon dioxide.

Answer:

B. carbon dioxide
