What supplies the heart with nutrient and oxygen rich blood??

Question

I'm pretty sure they are veins, but not sure if they're is an exact time like coronary??

Answer 1

Your lungs release oxygen into the blood, and your small intestine releases the nutrients.

Arteries always bring blood away from the heart, were as veins bring blood back.

Most of the time Arteries bring oxygenated blood away from the heart, and veins bring depleted blood back, but this is actually reversed in the pulmonary artery (brings depleted blood to the lungs), and pulmonary vein (brings rich oxygenated blood to the heart were it is distributed to the body through the arteries).

Answer 2

The heart tissue itself (cardiac musculature) is supplied by the branches of the Right and Left Coronary arteries which arise from the aortic sinuses. These arteries supply the heart with oxygen and nutrients.

The pulmonary veins bring in oxygenated blood from the lungs to the heart so that blood can be pumped by the heart to the body.
