WebMean arterial pressure (MAP) is defined as the product of cardiac output (CO) as well as total peripheral resistance (TPR). It is formulated as MAP = CO × TPR TPR is a designed variable, and the only MAP along with CO can be restrained.

WebResistance is how hard the vessel is trying to stop the flow of fluid. It's made up of how small the vessel is, and the friction along the sides. Flow is the amount of fluid that's passing through the vessel over an amount of time. It's determined by how much the pressure can push against the resistance.

The system relies on several hormones that act to increase blood volume and peripheral resistance. It begins with the production and release of renin from juxtaglomerular cells of the kidney.
