how does the blood flow throughout the body?

Question:

Answers:
Through veins, artilleries and capillaries powered by the pumping motion of the heart.

Other Answers:
its by the peristalic movement of the arteries and veins i think

your heart The Heart pumps the blood throught the body through the veins and it circulates it throught the body as well.

your heart pumps the blood, like a water pump would pump water out of the hose. You heart has valves that open and close with a pump.

I would like to provide a more detailed answer to your question. The flow of blood is continual; it has no beginning and no end. The heart is a good place to start though. The heart is made up of 4 chambers, the 2 atria and 2 ventricles. Between these chambers are valves, to ensure the blood only flows one way. The atria fill the ventricles, and the ventricles pump blood to the body. The left atrium receives oxygen rich blood from the lungs, and pumps it through the Bicuspid Semilunar, or Mitral, valve into the left ventricle. The left ventricle contracts and squeezes the blood through the Aortic valve and into the body. The very first few centimeters of the aorta travel vertically. At the base of the aorta, sitting on the top of the heart are the branches that feed the heart muscle itself. The Aortic valve closes these openings off during contraction, and the blood in the vertical portion of the aorta flows into the heart vessels.
The aorta branches into several smaller veins, traveling throughout the body, and eventually these veins branch into smaller venules. The venules then progress even further into capillaries. These capillaries are vessels with a will only a single cell thick, to facilitate particle exchange (diffusion). Capillaries are usually what bleed when we are injured, and the blood slowly oozes from the wound. The blood doesn’t actually leave the capillaries, but the oxygen, carbon dioxide and other wastes flow easily through the walls of the capillaries. Once the exchange of gasses has taken place, the blood then travels back toward the heart. The first type of vessel it encounters is the venule, simply a very small vein. Several of these venules feed into one larger vein and so on, until they have fed into the largest of the veins, the Superior Vena Cava (SVC). Inside the walls of veins are tiny flaps of vein wall that act as valves to prevent blood from flowing in the opposite direction. The people who answered before me brought up some good points, namely, the fact that blood is pushed back toward the heart by skeletal muscle contractions, thus making valves even more important. The pressure from the heart is nowhere as great in veins, and would not be able to return blood from the tips of our toes to our heart.
The SVC arches in a somewhat similar fashion as the aorta, flowing into the right atrium. The right and left atria contract at the same time, forcing blood into the ventricles. The right atrium feeds the right ventricle through the Tricuspid Valve. The ventricles also contract at the same time, forcing blood up and out of the heart. Oxygen poor blood from the right ventricles flows in to the pulmonary arteries, the only arteries that carry de-oxygenated blood, and into the same system of arterioles and capillaries through the network of lung tissue, each making its way to an alveolar sac to make another gaseous exchange. Once the exchange has been made, the blood, now rich with oxygen travels through the Pulmonary Veins, toward the left atrium of the heart, to begin the cycle all over again.
A very important feature of the human heart is its elasticity. When the blood reaches the atria, it flows through them, and directly into the ventricles. The purpose of the atria is to preload the ventricles. Much like a baseball pitcher who has to wind up for every pitch, the heart has to stretch its muscle so that it can contract with more force. Preload allows for some pressure to be present before contraction starts, so that more pressure is exerted, allowing the blood to flow to our vital brain, and our much overlooked feet. Without preload, the contraction of the heart would be substandard with its present muscular structure
