Question

Which of the following system of blood vessels is present in our body exclusively for the circulation of blood to and from the cardiac musculature?

• A. Portal system
• B. Pulmonary circulation
• C. Coronary circulation
• D. Both $\left(1\right)$ and $\left(2\right)$

Answer 1

Answer: (C)

Coronary circulation

The circulatory system is made up of blood vessels that carry blood away from and towards the heart. Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide. A special coronary system of blood vessels is present in our body exclusively for the circulation of blood to and from the cardiac musculature. Normal activities of the heart are regulated intrinsically, i.e., auto regulated by specialised muscles (nodal tissue), hence the heart is called myogenic.

So, the correct answer is (C)
