Explain, physiologically, why the erv and irv are lower during heavy exercise than they are during moderate exercise.

To meet the demand of more oxygen by the body.

Explanation: During the time of exercise the need for oxygen by the body increases. The minute ventilation of an individual will increase due to increase in the tidal volume and frequency of breathing.

The extra space is provided by the inspiratory reserve volume which acts as a reservoir of extra lung volume that can become inflated with air and as we need it.

So, Inspiratory reserve volume and expiratory reserve volume decreases during heavy exercise as there is a need of more inhalation of oxygen and more exhalation of carbon dioxide as tidal volume increases and cover the space.

your total amount per hour would be 26.53 dollars

subtract 40 dollars from 93.06 then divide 54.06 by 2, thats your answer

hope this !

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
