<h3>About RBC</h3>

RBC stands for Red Blood Cells. They are also called erythrocytes. They are circular, biconcave, disc-shaped and non -nucleated cells. They are formed in red bone marrows and destroyed in the spleen. Their lifespan is very short that is 4 months.

RBC contains an iron pigment called haemoglobin that carries oxygen from place to place in the form of oxyhemoglobin. When haemoglobin is exposed to oxygen, it turns red. So the blood is red in colour. If RBC is less in blood then, a person is suffering from anaemia , as there is not enough haemoglobin to transport oxygen.
