Which Circuit Has the Greatest Peripheral Resistance

Question

Which circuit has the greatest peripheral resistance?
A)hepatic circuit
B)pulmonary circuit
C)systemic circuit
D)venous circuit

Accepted Answer

The systemic circuit encompasses all blood vessels and organs in the body except for the lungs. It has the greatest peripheral resistance due to the large number and length of vessels, as well as the need to maintain blood pressure and flow throughout the body's tissues. The hepatic circuit only includes blood vessels and organs within the liver, the pulmonary circuit only includes blood vessels within the lungs, and the venous circuit refers to the portion of the systemic circuit that returns blood to the heart.
