Is there a difference between the amounts of blood pumped by each ventricle with each beat?

Answer 1

There's a difference in mine - I was born with Fallot's Tetralogy :)

Answer 2

Nope - each ventricle moves the same amount of blood out of itself with every beat. The difference is in how much TOTAL blood is moved by the ventricle - the left ventricle moves all of the blood in all of the arteries in the body. The right ventricle moves only the blood in the pulmonary arteries.

So, exit volume is the same, but actual volume moved is very, very different.

Answer 3

Brian L is right....

venous return (ie the amount of blood filling the right atrium in one minute) must equal cardiac output (ie the amount of blood pumped into the aorta in one minute) so that the heart functions well.

if cardiac output is more than venous return, the lungs will have a decrease in blood supply,

while if venous return is more than cardiac output, pulmonary edema (lungs fill with fluid) will occur because the heart will not be removing the excess blood coming to it.

hope that helped a little!!!

Answer 4

no; no relation in fact the sound of contracting musscles is the beat so each time when ventracles contract the sound corresponding comes out lub......dub....lub......dub so thats the reason when u run the heart beats faster that means heart is suppling more blood to the cells and the sound is also faster

Answer 5

no because your blood circulates
