Blood Flow Redirection During Exercise

Medium Biology Human Physiology

During physical exercise, the body undergoes various physiological changes to meet the increased demand for oxygen and nutrients in muscles. One major mechanism is the increased heart rate, which facilitates greater blood flow. However, the body must also ensure that blood flow is redirected towards active muscles while minimizing it to non-essential areas.

Which of the following statements correctly describes a mechanism that assists the body in achieving this redirection of blood flow during exercise?

Vasodilation of blood vessels in skeletal muscles due to increased levels of carbon dioxide.

Increased sympathetic nervous activity causing widespread vasodilation in all vascular beds.

Vasoconstriction of peripheral vessels while maintaining vasodilation in the coronary and cerebral beds.

Decreased blood pressure leading to increased blood flow to vital organs.
