coronary circulation

Coronary circulation refers to the flow of blood through the arteries and veins that supply the heart muscle with oxygen and nutrients. The coronary arteries branch off from the main aorta and deliver oxygen-rich blood to the heart tissue. After the heart cells use the oxygen, deoxygenated blood is carried away through smaller veins that eventually drain into the coronary sinus and then into the right atrium. This circulation is vital for maintaining the heart's function and health, ensuring it receives enough oxygen and nutrients to pump effectively. Blockages in these arteries can lead to heart attacks and other cardiac issues.
