How long does it take your heart to pump one pint of blood through your body?

Thanks for the feedback!
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 syste…m 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.
Through your veins or your arteries. Through your veins or your arteries.
Hmmm... well if the heart didnt plump blood thru our body we woukd be dead... no!! it dosent!! wat do u think?!?!?!?!?!?!?!
An average non athlitic person's heart will pump about 5 litres of blood per ventricle. per minute. (We Have 2 ventricles) That's 10 litres per minute. The average 160 lbs man… has about 4.7 litres of blood in his body. So if we do the math what do we get class?4.7/10=2.12 That means your blood will travel thru your body 2.12 times every minute. Now an athletic person's heart can pump up to twice this amount. (20 litres per minute. However people that are in peak physical shape usually have a much slower heart rate. The average persons heart will beat 72 times a minute as compaired to someone that trains for marathons whos heartrate could be as low as 45 beats per minute. It all works out to be the same with the exception that someone in good shape has a heart that has to work a lot less to accomplish the same task. Your heart has only so many beats it's good for. The harder it works the faster it will quit working.
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, a…mino acids, sodium, calcium and potassium salts in order to contract normally, these are all carried through the blood in our bodies 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.
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 back into the lungs and the process repeats.
more than 50 second for minutes
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
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 a minutes. This is called the beat rate. With each beat, the heart pumps about 60 to 70 milliliters of blood. If you multiply the two values together, you find that the cardiovascular output is just about four to five liters per minute.
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.
im not telling you
