How does the vasomotor centre control the distribution of blood during exercise?

The vasomotor center, located in the medulla oblongata of the brain, regulates blood flow during exercise by adjusting the diameter of blood vessels. It increases sympathetic nervous activity, causing vasoconstriction in non-essential areas (like the digestive system) and vasodilation in active muscles and the skin to enhance blood flow where it's needed most. This redistribution of blood helps to meet the increased metabolic demands of exercising muscles and maintain body temperature. Additionally, it works in concert with other physiological responses, such as increased heart rate and cardiac output, to optimize overall circulation during physical activity.
