Blood is pumped into the aorta, which carries oxygenated blood around the body. This unidirectional flow of blood through the heart shows that mammals have a double circulatory system.
6 mar 2021 · Blood Flow Through the Heart. Blood flow through the heart is made easy in this post! Using a simple diagram to show the order in which blood flows through the heart, we will walk through the cardiac circulation pathway in 12 simple steps.
The heart functions as a double ventricle. Blood moves from the body into the right atrium and then into the right ventricle, where it is pumped into the lungs. Blood becomes oxygenated in the lungs, moves into the left atrium and into the left ventricle, where it is pumped into the body again.
