What Are the Three Types of Circulation?
The three types of circulation that make-up the circulatory system of the body are systemic circulation, pulmonary circulation and portal circulation, according to the Franklin Institute. The three systems work together to ensure proper oxygenation and blood flow throughout the body.
Systemic circulation carries oxygenated blood from the heart to organs and tissues, according to the Franklin Institute. It then carries carbon-dioxide laden blood back to the heart. Pulmonary circulation carries that blood into the lungs where the blood is oxygenated and then returned the heart to circulate again. Portal circulation describes the circulation of blood from one organ to the capillaries of another, as described by the Franklin Institute.
