Blood is rerouted in the body primarily through the action of the heart and the network of blood vessels. During periods of increased demand, such as exercise, the body directs more blood to the muscles by constricting blood vessels in less active areas (like the digestive system) and dilating vessels in the working muscles. This process is regulated by the autonomic nervous system and various hormones, allowing for efficient distribution of oxygen and nutrients where they are most needed. Additionally, mechanisms like the opening of pre-capillary sphincters can redirect blood flow within specific tissues.
