During contraction it is pushed out, relaxing, it fills back up.

Contraction And Relaxation Of Heart

Flows in during relaxationa and out during contraction. Blood is always flowing through the heart as the heart is contracting on one side while it relaxes on the other side. That is how you get the bump bump when your heart beats.

Paradoxically, the blood flow to the heart muscle occurs on the relaxation of the heart. When the aortic valve opens during contraction, the valves occlude the coronary arteries. When the heart relaxes, the coronary arteries receive blood flow.

Relaxation. Think about it - if the muscles are all tight the blood can't squeeze through. Like when you make a fist and your hand turns white because there's no blood in it.

There's 3 chambers, the contraction and relaxation of them at various intervals causes blood to flow through the heart muscle constantly, and one contracts the other relaxes...One pushes the other opens to fill, constant flow and rythm.

During contraction. It is the contractions of the heart which moves the blood along.

The blood flows during relaxation. This only occurs during diastole(ventricule relaxation).

It's like a turkey baster: you squeeze it (contraction), the liquid moves out. you relese grip (relaxation) the liquid flow in.

it flows during contraction. the force of the contraction is what pumps it through the different chambers.
