MICROANATOMY

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: -Shunting occurs when blood return from one circulatory system (systemic or pulmonary) is recirculated to the same system, completely bypassing the other circulation.

Detailed explanation-3: -Portacaval shunting is a surgical treatment to create new connections between two blood vessels in your abdomen.

Detailed explanation-4: -Blood is pumped from the ventricles into large elastic arteries that branch repeatedly into smaller and smaller arteries until the branching results in microscopic arteries called arterioles. The arterioles play a key role in regulating blood flow into the tissue capillaries.
