What are erythrocytes
A
They are biconcave and they transport oxygen
B
They are red granules
C
Blue granules
D
None of the above
Explanation: 

Detailed explanation-1: -Erythrocytes (red blood cells or RBCs) are anucleate, biconcave cells, filled with hemoglobin, that transport oxygen and carbon dioxide between the lungs and tissues. They are produced in the red bone marrow by a process called erythropoiesis.

Detailed explanation-2: -RBCs are disc-shaped with a flatter, concave center. This biconcave shape allows the cells to flow smoothly through the narrowest blood vessels. Gas exchange with tissues occurs in capillaries, tiny blood vessels that are only as wide as one cell.

Detailed explanation-3: -The biconcave profile of the discocyte means that much of the mass is distributed in the periphery. This increases the moment of inertia of the cell and subsequently renders the erythrocyte less prone to rotation during flow in the large vessels.

Detailed explanation-4: -External Structure RBCs are disc-shaped with a flatter, concave center. This biconcave shape allows the cells to flow smoothly through the narrowest blood vessels. Gas exchange with tissues occurs in capillaries, tiny blood vessels that are only as wide as one cell.
