if a heartbeat pushes blood to an organ with that beat’s force, then after it reaches capillaries, how would the deoxygenated blood return to the heart? With the momentum reduced at capillaries or organs, which force drives the blood back to the heart?
In: Biology
The exact same force that pushes it to the organs. Assuming you’re not bleeding heavily, it’s a closed system. As oxygenated blood is “pushed” into the organ, through the arteries, the deoxygenated blood is pushed out, through the veins to be reoxygenated
