• 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.

Why does mammalian RBC lack cell organelles and nucleus?

Åñs:

Mammalian RBC lack nucleus and makes the cells biconcave and increase surface area for oxygen binding, loss of mitochondria allows the RBC to transport all the oxygen to tissues, and loss of endoplasmic reticulum allows more flexibility for RBC to move through the narrow capillaries.
