Question

How do the circulatory and respiratory systems work together for gas exchange?

Answer 1

The two systems work together in several ways. First, the respiratory system brings oxygen in the air to the alveoli in the lungs. The circulatory system then delivers the oxygen to the cells. Second, the circulatory system picks up carbon dioxide from the cells and carries it to the lungs, where it is released when we exhale

Answer 2

Simply put, the respiratory system provides oxygen and other necessary gases for cellular respiration and other cellular processes that take place in the circulatory system and beyond, the circulatory system then passes the wasted created by these processes back to the respiratory system which then expels them from the body.
