Blood supply to heart musculature is Via `:-`

Options

A. Cardiac artery
B. Coronary artery
C. Aorta
D. Pulmonary vein

Answer

To determine the blood supply to the heart musculature, we need to analyze the options provided:

1. **Cardiac artery**: This term is not commonly used in the context of blood supply to the heart. It may refer to arteries associated with the heart, but it is not the correct term for the specific arteries that supply the heart muscle.

2. **Coronary artery**: This is the correct answer. The coronary arteries are specifically responsible for supplying oxygenated blood to the heart muscle (myocardium). They branch off from the aorta and encircle the heart, providing the necessary blood supply for the heart to function effectively.

3. **Aorta**: While the aorta is the main artery that carries oxygenated blood from the heart to the rest of the body, it does not directly supply the heart muscle itself. Instead, the coronary arteries branch off from the aorta to supply the heart.

4. **Pulmonary vein**: This vessel carries deoxygenated blood from the lungs to the heart. It is not involved in supplying blood to the heart muscle.

Based on the analysis of the options, the correct answer is:

**The blood supply to the heart musculature is via the coronary artery.**

### Step-by-Step Solution:
1. Identify the options given for blood supply to the heart musculature.
2. Analyze each option to determine its relevance to the heart's blood supply.
3. Conclude that the coronary artery is specifically responsible for supplying blood to the heart muscle.
