what is the flow of blood through the heart and body
1 The blood then flows down through the mitral valve and into the left ventricle. 2  This is the part of the heart that pumps blood throughout the entire body. 3  After a quick burst through the aortic valve, the blood follows through the ascending aorta and out through the circulatory system to your toes.
From there the blood goes to the lungs where it gets fresh oxygen (C). From the lungs to the heart. After the blood is refreshed with oxygen, it's bright red. Then it returns to the left heart through the pulmonary veins to the left atrium.
