Question

lo 3.5. what does the coronary artery supply to the heart muscle? carbon dioxide - rich blood deoxygenated blood oxygen - rich blood iron - rich blood oxygen - depleted blood

Explanation:

The coronary artery is responsible for supplying oxygen - rich blood to the heart muscle. This is crucial for the heart's proper functioning as it needs oxygen to carry out its continuous pumping action. Carbon dioxide - rich blood (also known as deoxygenated blood) is carried by veins, not arteries. Iron - rich blood is not the specific supply related to the coronary artery's function for the heart muscle. Oxygen - depleted blood is what is returned from the body tissues to the heart (via veins) and then to the lungs for oxygenation.

Answer:

Oxygen - rich blood
