RBC:

1. Red Blood Cells (RBCs) are the type of cells that are present most abundant in the blood.
2. They are also known as erythrocytes.
3. RBCs are anucleate, biconcave, disc-shaped cells.

Haemoglobin:

1. RBCs/erythrocytes play an important role in the transport of oxygen to various tissues.
2. It is mainly due to the presence of an iron-containing, red-colored pigment called haemoglobin.
3. The presence of haemoglobin gives RBCs the red colour.
