During heavy exercise, the blood's volume flow rate is 5-10 times higher than when the body is at rest. Discuss different possible ways that a body can accomplish this

Explanation:

Aerobic respiration: During aerobic respiration, the muscles of the body during vigorous exercise experience lack of oxygen as a result heart pumps faster to avail the necessary blood volume of oxygenated blood to all the muscles.

Anaerobic respiration: In the absence of oxygen the glucose stored in muscles is converted into lactic acid and this process avails energy for performing work but also causes cramps in muscles.
