Question

Sinusoids are characterised by

• B. Absence of endothelium
• C. Mixing of blood and lymph

Answer 1

The correct option is A Irregular lumen

Sinusoids are characterized by a form of terminal blood channel consisting of a large, irregular anastomosing vessel having a lining of reticulo-endothelium and found in the liver, heart, spleen, pancreas, and the adrenal, parathyroid, carotid, and hemolymph glands.

So, the correct option is 'Irregular lumen'.
