Question

respiration during heavy exercise​

Answer 1

Answer:

This is similar to 'heart rate' in the cardiovascular system. If the exercise is intense, breathing rates may increase from a typical resting rate of 15 breaths per minute up to 40 – 50 breaths per minute. The most commonly used measure of respiratory function with exercise is known as VO2 (volume of oxygen uptake).

Answer 2

Answer:

During exercise there is an increase inphysical 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.
