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: -Instead, the sympathetic nervous system can stimulate the smooth muscle surrounding arterioles to constrict. This constriction of arterioles allows blood to be redirected to other areas of the body where blood is needed.

Detailed explanation-4: -Portacaval shunting is a surgical treatment to create new connections between two blood vessels in your abdomen.

Detailed explanation-5: -The hepatic vascular shunts can be divided into AP, portosystemic, arteriosystemic, systemic-venous, and portal-to-portal shunts.
