What is an advantage of a change in pulse rate after exercising

An increased blood flow carries excess waste products away from the active muscle cells.

Explanation:

The blood flow simply defines the amount of blood that passes through a given point in the circulation in a given period. Normally, blood flow is expressed in milliliters or liters per minute, but it can be expressed in milliliters per second or any other flow unit. when we are exercising, the heart works faster.
