Coronary artery supplies blood to `:-`

Options

A. Mammary glands
B. Rib muscles
C. Skin
D. Heart

Answer

**Step-by-Step Solution:**

1. **Understanding the Function of the Coronary Artery:**
- The coronary artery is responsible for supplying oxygenated blood to the heart muscle. It is crucial for the heart's function as it provides the necessary nutrients and oxygen for the heart to pump effectively.

2. **Analyzing the Options:**
- The question presents several options: mammary glands, rib muscles, skin, and heart. We need to determine which of these is supplied by the coronary artery.

3. **Evaluating Each Option:**
- **Mammary Glands:** The mammary glands receive blood from several mammary arteries, not the coronary artery. Therefore, this option is incorrect.
- **Rib Muscles:** The rib muscles are supplied by the anterior intercostal arteries, indicating that they do not receive blood from the coronary artery. This option is also incorrect.
- **Skin:** The skin receives blood from various other arteries, but not directly from the coronary artery. Hence, this option is incorrect as well.
- **Heart:** The coronary artery directly supplies blood to the heart muscles, making this the correct option.

4. **Conclusion:**
- After evaluating all the options, it is clear that the coronary artery supplies blood specifically to the heart muscle.

**Final Answer:**
The coronary artery supplies blood to the heart.
