Question

Vasa vasorum is a blood vessel, that supplies blood to
(a) Heart
(b) Lungs
(c) Another blood vessel
(d) Kidney

Answer 1

Hint: The name ‘Vasa’ is generally associated with another vessel. It is a smaller blood vessel that connects to the larger blood vessel such as the arteries and the veins. Also, the vessels which supply the heart, lungs, and kidney have specific names which direct us to that particular organ.

Complete answer:
Every vessel is made up of certain types of tissue and ultimately needs a blood supply of its own. Larger blood vessels have walls that are supplied with smaller vessels called ‘Vasa vasorum’. These vessels provide blood and nutrients to tissues and cells of the larger vessels like the aorta and vena cava. The word stands for the ‘vessels of the vessels’ which is derived from the Latin word. Hence, vasa vasorum is a blood vessel that supplies blood to another blood vessel.
-Vasa vasorum are divided into three main types – First is ‘Vasa vasorum internae’. It has its origin from the inside of a main artery or vein and it passes into the walls of the vessel.
-The second type is ‘Vasa vasorum externae’ which has its origin in the branches of the main artery and it returns to the main artery or vein in order to provide nourishment to the cells which are far away from the vessel interiors.
-The third type is ‘Venous vasa vasorum’ which has its origin in the main artery and then drains into the partner vein of this artery.

So, the correct answer is 'Blood vessel.'

Note:
The vessels which supply to the walls of the heart are called coronary arteries/veins. The ones which bring blood to the lungs for oxygenation are Pulmonary arteries and the ones which take oxygenated blood from the lungs to the heart are Pulmonary veins. A blood vessel supplying blood to the kidney is called a Renal blood vessel.
