Question

describe briefly shape, structure and function of human RBC​

Answer 1

The shape of the human red blood cell is known to be a biconcave disk. It is evident from a variety of theoretical work that known physical properties of the membrane, such as its bending energy and elasticity, can explain the red-blood-cell biconcave shape as well as other shapes that red blood cells assume.

• They are the most abundant cells in the human body.

• RBCs are formed in the bone marrow.

• The RBCs impart red colour to the blood due to presence of respiratory pigment haemoglobin.

• Matured mammalian RBCs do not have cell organelles and nucleus.

• They are biconcave and disc-shaped.

• Their life span is about 120 days.

• RBC is involved in the transport of oxygen from lungs to tissues.
