Question

Carbon dioxide levels in the blood are closely regulated to prevent the blood from becoming too acidic. When the rate of cellular respiration increases due to an increase in activity, like when an animal is running to escape from a predator, carbon dioxide production also increases. This increased production can lead to a higher concentration of carbon dioxide in the blood.

When the body detects an increase in blood carbon dioxide levels, the rate and depth of breathing both increase. This allows the body to expel the excess carbon dioxide that is delivered by the blood to the lungs, returning blood carbon dioxide levels to normal.

Which two body systems are interacting to maintain homeostasis by transporting acidic blood away from the cells and expelling excess carbon dioxide from the body?

A. circulatory and immune systems
B. circulatory and respiratory systems
C. lymphatic and immune systems
D. lymphatic and respiratory systems

Answer 1

Answer: B. Circulatory and respiratory

Step-by-step explanation:

The circulatory system carries acidic blood away from the cells, CO2 is expelled by the respiratory system
