In Heart
Blood is pumped through the body by the heart by two different circuits, one of the circuits in the systemic circuit and the second circuit is the pulmonary circuit.

The system circuit, starts via the left atrium and passing the mitral valve down into the left ventricle. The ventricle will then contract shortly after the atria have started relaxing and followed by the closing of the atrioventricular valves, so blood does not back wash into the atrium. Pressure will becoming higher in the left ventricle allowing ventricular systole's second phase to begin by forcing blood through the aortic semilunar valve up into the aorta so blood may reach the rest of the tissues in the body. Afterwards, the ventricles will becoming diastoling (relaxing) and pressure is now higher in the aorta then it is within the ventricles and this will cause back flow of blood back down to the ventricles but the aortic semilunar valve is has shut itself so blood may not backwash back into the ventricles. During this time, blood will be slowly returning back into the left atrium by ventricular diastole second phase & atrial systole but do note that the atrioventricular valves are still closed so blood doesn't wash into the ventriculars.

Blood will travel through arteries then to arterioles and lastly to capillaries so it may begin a gas exchange of oxygenated blood to the tissues to unoxygenated blood back to the heart, via the capillaries, venules, veins then superior & inferior vena cava.

Next is the pulmonary circuit which it will return the deoxygenated blood into the right atrium via the superior/inferior vena cava down the tricuspid valve to the right ventricle and blood will be forced up into pulmonary trunk via the pulmonary semilunar valve to the pulmonary arteries via the ventricular systole (same exact process as systemic circuits.) It will then travel towards the lungs, via the ateries then arterioles and capillaries once again but this time the capillaries with run along aveoli which are air sac's of the lungs that control the gas exchange between our atmosphere's....So, as you breath out you are going to be releasing the carbon dioxide from the tissues that were collected from those veins and transported via the arteries but as you breath in. oxygen will be inhaled back into the aveoli and will now allow oxygenated blood to return it back into the pulmonary venules then to the pulmonary veins to return back to the heart so it may re-enter back into left atrium and pass the mitral valve into the left ventricle via ventricular systole and back through the aortic semilunar valve to the aorta and to the rest of the bodies tissue.

Which part of the heart pumps blood to the body?

The ventricles are the two lower chambers of the heart. The right ventricle pumps de-oxygenated blood to the lungs to drop off carbon-dioxide and pick up oxygen. The left ventricle pumps oxygenated blood to the rest of the body and is the strongest chamber

Why does the heart pump blood around the body?

The Heart pumps your blood around your body because if it didn't you would die. You would die, because blood creates energy around your body, and if a certain part (let's say it's the leg) doesn't get enough blood there, it would fall asleep, and eventually fall off. Do you want your leg to fall off (MORE)

Does the heart pump blood to the body?

Yes, the heart does pump blood to the body. The heart pumps blood away from it and to the body through arteries, and then the blood comes back to the heart through veins (If you need this information for a quiz, an easy way to remember this is: arteries: away, and so obviously veins: to the heart).

How blood flows through the heart and body?

The heart squeezes the blood out (valves keep it from going backwards) into the large arteries. The arteries are elastic (like long, skinny balloons). How much flows out at the other ends depends on how many capillaries are open at any given time. They open and close depending on the (partial) press (MORE)

Which side of the heart pumps blood to the body?

The left side of the heart pumps blood to the body. The right sideof the heart receives the oxygen depleted blood from the body andsends it to the lungs. The left side then gets the oxygen enrichedblood from the lungs and sends it out into the rest of the body.

How does blood pump through the heart?

The blood flows through the heart by: . Going through an atrium which leads to a ventricle . Then from the ventricle, it goes to a blood vessel hwich leads to the heart . A wall between the two atriums or the two ventricles keeps the blood rich in oxygen and separates it from blood with little ox (MORE)

Why does the heart pump blood through the body?

The heart pumps blood around the body because it carries oxygen and glucose to the brain, without them a person will loose consciousness. Muscles need oxygen, glucose, amino acids, sodium, calcium and potassium salts in order to contract normally, these are all carried through the blood in our bodie (MORE)

Why does the heart pump blood around pour body?

Our heart pumps blood around our body because... when we breath in oxygen it travels down our windpipe and into our lungs where it flows into our blood stream which the heart pumps round and to our muscles with are supplied with the oxygen which it needs to keep going! few, its a long story!

Which chamber of the heart pumps blood through the body?

Oxygenated blood flows from the lungs by pulmonary arteries and veins into the right atria and ventricle which then flows through the aortic semilunar valve into the aorta to the rest of the body which then flows back into the heart through veins and arteries into the left atria and ventricle and ba (MORE)

Which heart chamber pumps blood throughtout the body?

Though both ventricles of the heart pump blood out of the heart and into the body, I assume you're talking about the chamber that pumps blood to the capillaries of the head and arms or abdominal organs and legs. This would be the left ventricle, which receives oxygenated blood from the left atrium a (MORE)

What does blood do when it is pumped through the body?

After being oxygenated in the lungs, the blood enters the left atrium via the pulmonary veins. The left ventricle pumps the oxygenated blood to the rest of the body via the aorta. Blood cells carry oxygen, and the liquid portion of the blood, called plasma, carries the nutrients needed by the cells (MORE)

Why does your blood need to be pumping through your body?

(Just guessing to the best of my ability.) Because without blood circulation your body would become stiff, and start to rot away. Basically, your body needs to pump blood so all of your organs will continue to function and to keep your body from just stiffening up and becoming a chunk of dead mea (MORE)

How long does it take for your heart to pump blood around the body?

For a person at rest, it takes just about one minute. If you are more active, it will take less time. Exactly how long depends on several things: the rate at which your heart beats, how big your heart is, and, to a certain extent, how big you are as well. A person's heart beats about 65 to 75 times (MORE)

How does the blood flow through the heart to the body?

A very simplistic explanation: If we start with the aorta (the biggest artery in the body), the oxygenated blood from the heart travels through this around the entire body and supplies oxygen, nutrients, etc. The deoxygenated blood then travels back to the heart via the venous systems and enters th (MORE)

Does heart pump blood to body after removal of brain?

The heart and body will no longer pump blood throughout the body without the brain to give commands to do so.Without a brain the body will no longer know how to eat,breathe,move or talk.technically speaking,without a brain the body will shut down and die.

What does the heart pump blood through so it moves around the body?

The heart acts as a powerful pump to push the blood through theveins, arteries & capillaries to carry oxygen & sugar tofuel the muscles & organs that keep us alive; then carries thedepleted blood to the lungs to pick up oxygen & the intestinesto replenish the sugar

Which side of the heart pumps blood through the arteries?

Humans: blood enters the right atrium, collects, get dumped into the right ventrical, gets pumped to the lungs, collects in the left aurical (atrium), gets dumped into the left ventrical, guts pumped into the aorta (a blood vessel) and to the body! Figure it out.
