Question

How does gas exchange occurs when the circulatory and respiratory systems work together

Answer 1

The circulatory system helps to pump blood throughout the body. This is important because red blood cells work to carry oxygen throughout the body. The respiratory system is what allows us to breathe in this oxygen that is later absorbed by red blood cells. The respiratory system also extracts carbon dioxide from the blood which we later breathe out.

Answer 2

The respiratory and circulatory systems work with each other in this manner, the respiratory system will obtain oxygen then the circulatory system brings the oxygen to different parts of the body then it also takes carbon dioxide from different tissues of the body and bring carbon dioxide to lungs then the respiratory system takes carbon dioxide outside the body during exhalation
