Question

write about coronary veins and coronary arteries

Answer 1

Coronary arteries labeled in red text and other landmarks in blue text.Coronary circulation is the circulation of blood in the blood vessels that supply the heart muscle (myocardium). Coronary arteriessupply oxygenated blood to the heart muscle, and cardiac veins drain away the blood once it has been deoxygenated.

Answer 2

The coronary sinus is a collection ofveins joined together to form a large vessel that collects blood from the heart muscle (myocardium). It delivers less-oxygenated blood to the right atrium, as do the superior and inferior vena cavae

The coronary arteries are the arteries of the coronary circulation, which transports bloodinto and out of the cardiac muscle. They are mainly composed of the left and right coronary arteries, both of which give off branches.
