Question
In the control of breathing, what is the factor that is most closely monitored by chemoreceptors?
Why do larger animals have complex internal systems to exchange nutrients and wastes with their environments?
The respiratory and cardiovascular systems of vertebrate animals work in tandem to transport oxygen to metabolizing tissues and to eliminate carbon dioxide as a waste gas. Which of the following statements accurately describes how these systems interact for gas exchange?
The amount of ammonia in the bloodExplanation / Answer
1.
In the control of breathing the amount of CO2 in the blood is most closely monitored by the chemoreceptors. This is because CO2 help in maintaining the pH and change in pH rapidly sense by the chemoreceptors.
2.
Larger animals have complex internal systems to exchange nutrients and wastes with their environments Because there is not sufficient surface area on the outside of a large animal for the exchange required by their body mass (volume).
3.
The correct statement is that the rate of oxygen transport by diffusion across the lungs must generally match the rate of transport by the circulatory system.
