Answer 1

9)Lacteals are the lymphatic vessels which absorb the digested fat from the small intestine .Then they are transported to the thoracic ducts which finally opens into the right atrium .

So answer is D.

10)Spleen has both afferent and efferent vessels. So it can filter lymph.

It is not present in the small intestine.

It is not the usually site of hemopoiesis in adult. The normal site is bone marrow.It is the site of extramedullary hemopoiesis.

T cells mature in the thynus.

So the answer is C.

11)All the three are function of the lymphatic system.So answer is D.

12)Right and left coronary arteries are the first branches of ascending aorta(.Veins are not the branches .Veins join a vessel ; arteries branch from a vessel )
