contraction and relaxation of the heart muscles
contraction and relaxation of the heart muscles
Circulation of the blood is divided into blood that is being pumped away from the heart, and blood that is returning to the heart. Blood leaves the heart through arteries, and returns to the heart through veins. The connecting vessels between arteries and veins are the capillaries.
The heart is protected by the cardiac muscle which is an involuntary muscle that allows the heart to pump blood.
the valves
The heart pumps blood through the body via the cardiovascular system. Blood allows for transfer of nutrients and waste to and from cells in the body.
It allows deoxygenated blood from the heart muscles to get back to the chambers of the heart to continue in the circulatory system.
The aortic valve allows the blood to leave the left ventricle.
The veins bring blood back to the heart are weak and not working as they should. That allows blood to 'pool' in them.
The primary force that moves the blood is the heart. The heart contracts and pumps blood into and out of the heart and into veins or arteries. There is a difference between the two, i suggest looking up these differences. This pumping allows you to have a pulse and thus, live. The primary force that moves the blood is the heart.

The bicuspid valve allows blood to pass from the heart to the aorta but then keeps it from flowing back into the heart.

The aorta carries blood from the heart to the rest of the body.
