Question

Which veins which supply blood to heart?

Answer 1

The coronary arteries (veins always take blood away from the heart) supply the heart with blood.

Explanation:

Known collectively as the cornary circulation, a system of arteries brings oxygen (and nutrient) rich blood to the surface of the heart. There are two main vessels known as the left and right coronary arteries.
They enter the heart through coronary ostia (which are near the aortic valves) and they run along the surface, supplying the heart with blood.

I hope this helped, let me know if i can do anything else:)
