Answer 1

Answer:

Normal respiration rates for an adult person at rest range from 12 to 16 breaths per minute.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).
