A special coronary system of blood vessels present in our body exclusively for the circulation of blood to and from the -

Options

A. Corneocytes
B. Cornea
C. Cori cycle
D. Heart/Cardiac musculature

Answer

**Step-by-Step Solution:**

1. **Understanding the Coronary System**: The coronary system refers to the network of blood vessels that supply blood to the heart muscle itself. It is crucial for the heart's function as it provides the necessary oxygen and nutrients.

2. **Identifying the Main Components**: The primary components of the coronary system are the coronary arteries and veins. The coronary arteries branch off from the aorta, which is the main artery that carries oxygenated blood from the heart to the rest of the body.

3. **Function of the Coronary Arteries**: The coronary arteries are responsible for delivering oxygenated blood to the heart muscle (myocardium). This is essential because the heart requires a constant supply of oxygen to function effectively.

4. **Formation of Capillaries**: Once the coronary arteries reach the heart muscle, they further divide into smaller arteries and eventually into capillaries. This is where the exchange of gases (oxygen and carbon dioxide) and nutrients takes place.

5. **Return of Deoxygenated Blood**: After the oxygen has been delivered and carbon dioxide has been picked up by the heart muscle, the deoxygenated blood is collected by the coronary veins. These veins then drain the blood back into the right atrium of the heart.

6. **Conclusion**: Therefore, the special coronary system of blood vessels is exclusively for the circulation of blood to and from the heart muscle. The correct answer to the question is that the coronary system circulates blood to and from the heart.

**Final Answer**: The special coronary system of blood vessels present in our body is exclusively for the circulation of blood to and from the heart.
