What is the difference between white blood cells and red blood cells?

Red blood cells (RBCs) and white blood cells (WBCs) are two distinct types of blood cells that differ in several aspects, including their morphology, quantity, and function.

1.Morphology: Red blood cells are red in color due to the presence of hemoglobin and have a biconcave disc shape. In contrast, white blood cells are relatively larger and have a round, sphere-like appearance.

2.Quantity: In adult males, the average count of red blood cells per milliliter of blood is 4-5 million RBCs, while in adult females it is 3.5-4.5 million RBCs. On the other hand, the average count of white blood cells per milliliter of blood is 4000-10000 WBCs in adults.

3.Function: Red blood cells play a crucial role in transporting oxygen and carbon dioxide throughout the body. They release oxygen in the tissues and carry carbon dioxide from the tissues to the lungs for disposal. White blood cells, on the other hand, are primarily responsible for immune function. When a foreign agent or pathogen enters the body, white blood cells can change their shape to pass through the walls of blood vessels and reach the site of infection. There, they surround and engulf the foreign agent or pathogen to eliminate it from the body.

In summary, red blood cells and white blood cells differ in their morphology, quantity, and function. Each type of cell performs distinct roles in maintaining proper bodily function.
