Erythrocytes/ Red Blood Cells (RBCs) - 100x

An erythrocyte is a disc-shaped cell with a thick rim and a thin sunken centre and has two main functions:

1- To pick up oxygen from the lungs and deliver it to tissues elsewhere

2- To pick up carbon dioxide from other tissues and unload it in the lungs

Normal RBC range is:

Male: 4.7 to 6.1 million cells per microliter (cells/mcL)

Female: 4.2 to 5.4 million cells/mcL
