The heart delivers blood to itself, one half gets "fresh" blood, while the other half gets the blood that comes back after being circulated through the entire body.
oxygenated blood frm lungs and deoxygenated frm others organs
Veins carry blood to the heart.
veins
coronary bypass
The pulmonary arteries deliver blood to the lungs from the heart so it can be oxygenated.
The coronary artery delivers oxygenated blood to the heart. The coronary arteries supply the heart muscle with oxygen and nutrients.
The right atrium is where the blood enters the heart.
Of course heart muscles need a blood supply for the cellular respiratory process as the blood carries the final electron acceptor oxygen which is key to oxidative phosphorylation in humans.
The coronary arteries deliver blood to the muscles of the heart.
Blood with no oxygen (the blood that flows to the heart picks up oxygen from the lungs).
veins that deliver oxygen poor blood from the body to the heart.
left side of heart
coronary bypass
Capillaries deliver blood tot he muscle of the heart. In fact, it is about 1 capillary per contractile cell of the heart. These cells require a rich blood supply since they are very active cells.
Remember veins back to the heart. This goes into the heart to deliver oxygen.
capillaries
veins move blood to the heart; arteries move blood away from the heart. Blood goes from the heart to the lungs to get oxygen, then back to the heart, then to the body (to deliver the oxygen), then back to the heart, where it starts the process over again.
diastole
The pulmonary arteries deliver blood to the lungs from the heart so it can be oxygenated.
The function of the circulatory system is to deliver blood to the body and back to the heart
