Characteristics of Human Leukocytes

Leukocytes, also known as white blood cells, have several characteristic features:

1. Presence of Hemoglobin: - Leukocytes do not contain hemoglobin, which is the protein responsible for carrying oxygen in red blood cells.

2. Biconcave Disk Shape: - Unlike red blood cells, which have a biconcave disk shape, leukocytes have irregular shapes with extensions called pseudopods that help them move and engulf pathogens.

3. Presence of Nucleus in Mature Cells: - Unlike red blood cells, mature leukocytes have a nucleus. This is a key feature that distinguishes them from red blood cells.

4. Ability to Reproduce Through Mitotic Division: - Leukocytes have the ability to reproduce through mitotic division, which is essential for maintaining the body's immune response.

Leukocytes play a crucial role in the body's immune system, defending against infections and foreign substances. Their diverse characteristics and functions contribute to the body's overall defense mechanism.
