The heart is a large muscle which acts like a pump and pushes the blood around the body
The heart acts as a two way pump. It squeezes blood out of it but also sucks it in. The veins are very narrow, which increases the pressure. They also have one-way valves.
it help to move the blood around your body
To move blood around the body, to and from the heart.
your blood circulates around your body because your heart pumps when you walk or run, or do anything physical
The faster your heart beats the faster blood flows.
More blood is pumped around the body because the heart beats more. When the heart beats more the that makes the blood move around the body faster :)
the valve in the heart makes sure that blood moves around your body, it also makes sure that the blood travelling around your body is travelling int he right direction.
I think the answer is blood vessels. I hope I was right. :)
If you don't have blood pumping around the body, the heart wouldn't be able to get everything it need in the blood stream to work and if the heart doesn't work most of your muscles won't work either causing you to die. :(
An artery will always move blood from the heart to the rest of the body as a vein will always move blood from the body back into the heart, whether or not it is oxygenated or not.
The contractions and relaxation of the muscles in the heart cause the blood to be pumped around the body. The contractions push the blood out of the heart and cause it took be pushed around the body in 0.8 seconds. Other muscles in the heart relax so blood may flow into another chamber of the heart.
The circulatory system (blood and vessels) transports oxygen and nutrients around the body. The heart furnishes the power to move the blood.
Blood pressure. When the heart beats, it creates blood pressure during the ventricle contraction that move blood throughout the body. The most powerful is the left ventricle. If the blood coming out of the top of the heart was to escape, it could shoot a stream of blood 16 feet into the air.
