During hazy exercise the breathing rate of a person slow down
Answers
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:
During exercise, the muscle cells need more oxygen to sustain their work This results in an increase in breathing and heart rate because both the lungs and the heart work extra to keep up with the ever growing need of oxygen.
Fermentation takes place in the muscle cells during exercise which results in an increase in the amount of lactic acid, hydrogen ion. This stimulates the respiratory system more and it results in an increase in the heart rate so that the heart pumps more blood. The blood pressure increase which leads to more blood flow in the alveoli.
The lungs absorb more oxygen and the muscle cells receive more blood and thus the oxygen demand is satisfied.
Therefore this statement is false
