Question

Why do we breathe faster after some kind of physical activity ?​

Answer 1

Explanation:

$\huge\mathbb\red{☆ANSWER☆}$

• During exercise there is an increase in physical activity and muscle cells respire more than they do when the body is at rest. The heart rate increases during exercise. The rate and depth of breathing increases - this makes sure that more oxygen is absorbed into the blood, and more carbon dioxide is removed from it.
