ANATOMY

Detailed explanation-1: -During exercise, the cardiovascular system redistributes the blood so that more of it goes to the working muscles and less of it goes to other body organs such as the digestive system. This redirection of blood flow is caused by a mechanism (or process) called the vascular shunt mechanism.

Detailed explanation-2: -Vascular shunting is the process of redistribution of blood. • Blood diverted to active areas and diverted away from inactive areas. • Occurs through vasoconstriction (narrowing of arteries) and vasodilation (widening of arteries).

Detailed explanation-3: -During exercise, blood flow to muscles increases to meet the increase in oxygen demand. This redirection of blood flow to the areas where it is most needed is known as a vascular shunt.

Detailed explanation-4: -The vascular shunt mechanism is controlled by the Vasomotor control centre (VCC) in the Medulla Oblongata. The VCC receives information from Chemoreceptors and Baroreceptors about chemical and pressure changes.

Detailed explanation-5: -As you exercise, your muscle cells consume more and more energy, leading to a decrease in nutrients and an increase in molecules such as carbon dioxide. This can lead to vasodilation, as the muscles you’re exercising require more nutrients and oxygen.
