Question

5) Describe the blood vessels involved in coronary circulation 6) Explain the pathway (or blood vessels) involved in pulmonary and systemic circuit.

Answer 1

Ans:- 5

Blood vessels involved in coronary circulation are as follows:-

- Coronary arteries

- Cardiac veins

Coronary arteries supply oxygenated blood to the heart muscle and other components of the heart.

Cardiac veins drain away the blood once it has been deoxygenated. These includes the great cardiac vein, the middle cardiac vein , the small cardiac vein and the anterior cardiac veins.

6.

Pathway involved in pulmonary and systemic circuit is as follows:-

Pulmonary circuit:- The correct path of a drop of blood through vascular system is right atrium, right ventricle, pulmonary arteries, lungs, pulmonary veins, left atrium, left ventricle, aorta, arteries, arterioles, capillaries, venules, veins and then vena cava.

Systemic circuit:- It carries oxygenated blood from the left ventricle, to the aorta, to every organ and tissue in the body, and then back to the right atrium. The arteries, capillaries and veins of the systemic circulatory system are the channels through which this long journey takes place.
