How does blood pump through the heart?
The blood flows through the heart by:
(You only really need #1 and #2 to answer the question)
- 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 oxygen.

It pumps blood with extremely organised contractions of the four chambers. The contractions of the chambers increase the pressure and flow rate of the blood out of the heart. The heart will continue to circulate the blood as long as there is sufficient volume (ex: no hemorrhage, dehydration, electro…lyte imbalance) because the heart relies on gravity and pressure gradients to fill; meaning it cannot pull the blood back from the veins to the chambers.

A combination of things causes the heart to pump and several conditions can interfere with the heart pumping. However, the left ventricle is the workhorse of the heart. It is said, in figuring comparisons, the heart can shove a steamship up on the beach it is so strong. We have 3 electrical nodes (…to simplify explanation) in the heart, one at the top, one at the bottom, one in the middle. Electrical impulses travel from one to the other causing the heart impulses. It is said heart muscle will beat on its own even in a lab setting it is so "electrical". As the heart depolarizes from these nodes it "beats". We all have a natural "pacemaker", located in the right atrial wall of the heart. This "pacemaker" sets the heart's "sinus rhythm" of 70-80 bpm. Heart muscle is different from any other in the body.

The heart pumps to all parts of the body by the help of twoprocesses. Name them.
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).
Your heart pumps blood by contracting and releasing. That is the beat you feel. As it contracts, it pushes blood through the heart and valves close behind it then the heart releases and it fills with more blood.
Average cardiac output is 5 liters per min. so about 7200 liters per day. 5 litres per minute = 300 litres per hour = 7200 litres per day.During excercise this can increase to 30 litres per minute = 1800 litres per hour = 43,200 per day but this would not be sustainable.
As the heart pumps, systolic pressure on the arteries pushes the blood through the arteries into the veins. This continuous pressure circulates the blood back into the heart. Just like a water pump on a car's engine pumping water through the engine, radiator and back to the water pump to start the p…rocess again. (MORE)
Well think of the heart and blood vessles as a race track. It start at the heart goes all they way around then back to the start so the heart pumps blood to the heart, but also ateries have a layer of smooth muscle that automatically contracts to help the movement of blood.
If oxygenated blood from the lungs to the heart is not pumped to the rest of the body, by the heart, then tissues will die from lack of oxygen (and other nutrients transported in the bloodstream). Blood needs to reach all tissues and cells, and can only do so if it propelled to them by a pressure gr…adient (the pressure being highest in the large arteries, and gradually less until reaching the capillaries, where the pressure is very very low).

The heart has four chambers, two atria and two ventricles. Blood enters the heart by way of the right atrium and passes into the right ventricle. After the right ventricle it travels to the lungs to be oxygenated and then back to the left atrium and into the left ventricle. The left ventricle is the… pressurizing part of the heart and the last stop before artiral circulation begins. Please consult a good college anatomy text book for further explanation. (MORE)
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 con…tract 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.

The Heart is a muscular organ that pumps blood to all parts of the body. Your heart works as a pump that pushes blood to the organs, tissues, and cells of your body. Blood delivers oxygen and nutrients to every cell and removes the waste products made by those cells. Blood is carried from your heart… to the rest of your body through a complex network of arteries, arterioles, and capillaries. Blood is returned to your heart through venules and veins. (MORE)

No. Heart pumps blood only to places. However, the circulatory system is, well, circular and the blood that has been pumped away will eventually return to the heart via the veins since more and more blood would be pumped from the blood to fill its place.
Quiver is diff from pump. Do NOT get it mix up. That said it pumps more or equal to amount blood. Or more. Heart quivers are a doctor consultable illness/abnormalormalality. Please consult and consult.
Veins carry deoxygenated (blood lacking oxygen) blood back to the heart. Arteries carry oxygenated (blood with oxygen in) blood away from the heart and around the body.
Hmmm... well if the heart didnt plump blood thru our body we woukd be dead... no!! it dosent!! wat do u think?!?!?!?!?!?!?!
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…s from the foods we eat and the air we breathe. Without blood circulating the body, it begins to shut down and after a very short period of time will die. (MORE)
Nothing really happens to the blood as it is pumped through the heart. The blood just gets redirected and sent to a location in the body.
The heart pumps blood in two ways - 1. To distribute blood to all living cells of the body, by means of the arteries, providing oxygen, nutrients, vitamins and hormones. Also to carry the waste products of cell metabolism by the veins i.e. carbon dioxide, toxins back to the heart. This is called… the systemic circulation. 2. To pump blood to the lungs to expel waste gases mainly carbon dioxide, and to carry oxygen diffused by the lungs back to the heart ready to be circulated again. This is called the pulmonary circulation. (MORE)
The heart pumps blood not to it. The right atrium pumps to the right ventricle, the right ventricle pumps to the lungs, the left atrium pumps to the left ventricle, the left ventricle pumps to the the body (except the lungs). Well that is in normal anatomy anyway.
The heart contracts to push blood out, and expands as blood already sent around the body is pushed back into the heart. I believe they are called LUBS and DUBS, feel free to correct that last part if needed.
These "doors" are the following valves: . Tricuspid Valve - arterioventricular valve of the right side . Pulmonary Semilunar Valve - right side of the heart . Mitral or Bicuspid Valve - AV valve of the left side . Aortic Semilunar Valve - left side of the heart

The Aorta, the main artery. It leaves the heart from the left ventricle and delivers oxygen rich blood to 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…ck into the lungs and the process repeats.

What valves are open during the process where the blood is pumped from the heart to the body through the aorta?
the four valves in the heart are -tricuspid -pulmonary semi-lunar -bicuspid -aortic semi-lunar the aortic semi-lunar is valve the blood flows through when the described circumstance occurs but both of the semi-lunar valves open and close at the same time because both ventricles pump simultaneously
yes it is. the blood travels through tubes in the body called vessels. there are 4 types of vessel but i can't be bothered listing them!!!the smallest is the capillary vessel
not entirely, if the blood flow stops,so does the heart, but the heart is mainly used to keep the blood flowing so it can get to different parts of the body. Electricity can keep a heart pumping if the correct amount of flow is being produced so blood can be replaced for the heart but cannot sustain… a human body. (MORE)
Which valves are open during this process of which the blood is pumped from the heart to the body through the aorta?
During ventricular systole both ventricles contract, forcing the blood out of them and into another vessel. The left ventricle is the one that provides blood to the rest of the body. As it contracts, the high pressure causes the aortic semilunar valve to open, and blood travels through it to the aor…ta. (MORE)
Yes. Just like any other animal that has a heart, the function of a frogs heart is to pump blood to all of its body's tissues.
The involuntary muscle is constantly contracting and expanding to supply oxygen rich blood to the body.
The left ventricle. Blood from the body comes into the right atrium goes into the right ventricle and is then pumped to the lung comes back to the left atrium and then left ventricle to the aorta to the body.
The heart is a muscle which is constantly contracting and relaxing. the force of this contraction and relaxation causes the blood to rush through the veins and arteries of your body. another way of looking at it is if you think of the heart as an air pump. when you squeeze and let go of the air pump…, that causes air to move. it is the same with the heart.

no it doesnt or you would be breathing in blood and that makes no sense.
Your brain sends a signal to your heart creating magnetic pulses onto the feet and exploding out of the heart killing every human and alien life around you, turning them into zombies -sorry mate
It is important that the heart pumps blood so you can receive that blood to important limbs and arteries and anywhere else it is needed.
The heart is a muscle, but it is NOT in the muscular system, and pumps blood to all parts of the body :)
That is what is the job of a heart.By pumping it apply pressure on the blood so that it reaches ever part of our body.
the blood is pumped to the lungs in order to get oxygen and become oxygenated and thus supply the body cells and tissues with oxygen
Left Ventricle * Blood flows through the mitral valve (also known as the bicuspid valve) into the left ventricle. * Contraction of the ventricle closes the mitral valve and opens the aortic valve at the entrance to the aorta. * The first branches from the aorta occur just beyond the aortic v…alve still within the heart. * Two openings lead to the right and left coronary arteries, which supply blood to the heart itself. Although the coronary arteries arise within the heart, they pass directly out to the surface of the heart and extend down across it. They supply blood to the network of capillaries that penetrate every portion of the heart. * The capillaries drain into two coronary veins that empty into the right atrium. . http://answers.yahoo.com/question/index?qid=20080707203519AAgh3e5 More: In mammals, the function of the right side of the heart is to collect de-oxygenated blood, in the right atrium, and pump it, through the tricuspid valve, via the right ventricle, into the lungs, (pulmonary circulation) so that the carbon dioxide can be dropped off and oxygen picked up. The passive process of diffusion happens on this stage. The left side collects oxynated blood from the lungs into the left atrium. From it the blood moves to the left ventricle, through the mitral valve, also called bicuspid valve, which pumps it out to the body, (via the aorta) . (MORE)
The muscles of the left ventricle pumps blood through the aortic valve into the aorta, in the heart, from which the blood is distributed throughout the body.
The brain sends a signal to the sinoatrial (SA) node of the heart, initiating a wave of contraction throughout the heart. Blood flowing into the heart's right atrium, then into the right ventricle, then through the pulmonary artery to the lungs to exchange out carbon dioxide waste and fresh oxygen i…nflow. That blood is then pumped back into the heart via the pulmonary vein into the left ventricle. It's pumped into the left atrium, and out the aorta to the rest of the body. (MORE)
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
It is pumped out THROUGH the ventricles, not BY them. The pump isthe heart - or more specifically the contractions and expansions ofthe heart.
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.
The heart is a four chambered pump, whose sole task is to pumpblood round the body.
The human heart is a four chambered muscular organ, whose sole taskis to pump blood round the body.
From the blood it is pumping, the blood pervades are organs andcarries food /energy for those organs to function.
