Answer:
An increased blood flow carries excess waste products away from the active muscle cells.
Step-by-step 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. This influences the speed of blood flow that begins to circulate faster. The advantage of this is that increased blood flow removes excess waste from active muscle cells and this prevents muscle fatigue and cramps.
