blood flow regulation

Blood flow regulation is the body's way of controlling how much blood reaches different tissues based on their needs. This process involves the heart pumping blood while blood vessels can widen or narrow to adjust flow. For example, when you exercise, muscles need more oxygen, so vessels open up to increase blood supply. Hormones and signals from the nervous system also help manage blood flow during various activities and conditions, ensuring that each part of the body receives adequate blood to function properly, whether at rest or during exertion.
