At the time of pulsing, every living heart relaxes and fills
blood (called diastole). Furthermore the heart contracts and
pump blood out of the heart (called systole). Both
porch relax and contract simultaneously, and
The second chamber also relax and contract simultaneously.
Blood contains little oxygen and contains many
carbon dioxide from the body flows through the two vessels
behind large (vena cava) to the right into the foyer. After
Right porch filled with blood, he would push the blood into the
right chamber. Blood from the right chamber will be pumped through the valve
pulmonary artery to the pulmonary veins, leading to the lungs. Blood
will flow through very small vessels (capillaries) that
around the air bag in the lungs, absorbing oxygen and
the subsequent release of carbon dioxide exhaled. Blood
which is rich in oxygen (clean blood) flows in the veins
pulmonary veins to the left of the foyer. Circulation between
the right side of the heart, lungs and left the porch called the circulation
pulmonary.
