Flow through the heart:
Blood enters into the heart through the Superior and Inferior Vena Cava into the Right Atrium. Then from there goes through the Tricuspid Valve into the Right Ventricle, then through the Pulmonary Valve into the Pulmonary Artery and out of the heart to the lungs. Then enters back into the heart through the Pulmonary Veins and into the Left Atrium then through the Mitral Valve down to the Left Ventricle. From there pumps through the Aortic Valve into the Aorta and out to flow throughout your body.
The simple way of explaining the flow throughout the body:
It flows out of the Aorta through Arteries that take your blood throughout your body. The Descending Aorta is large and carries blood downward into more arteries that flow through all of your organs and down to your Pelvic Region to the Iliac Artery and down through your lower extremities through the Femoral Artery. Then there's the Carotid Artery that takes the blood up from the Aorta to our neck and brain. and goes into the arms through the Subclavian Artery. Once it does all this it transfers back from the arteries to the veins. The blood from the arteries goes into little arterioles which is connected to small capillaries and on the other side of those capillaries are Venules which connect to the veins. Then blood is draw into the heart from the veins and the process starts all over again. Crazy that all of this happens each time you feel you feel your heart beat.
