What type of cells do leukocytes represent in the body?

Leukocytes are a critical component of the immune system, functioning primarily as white blood cells. Their primary role is to protect the body against infections and foreign invaders, such as bacteria, viruses, and other pathogens. They play a vital role in the inflammatory response and are involved in both the innate and adaptive immune systems.

Leukocytes differentiate into various types of cells, including lymphocytes, neutrophils, monocytes, eosinophils, and basophils, each with specific functions in immune response. This diversity is essential for the body to mount an effective defense against a wide range of threats.

In contrast, red blood cells are responsible for transporting oxygen throughout the body, platelets are crucial for blood clotting, and muscle cells are involved in movement and contraction. Understanding these distinctions emphasizes the unique and essential role that white blood cells, represented by leukocytes, play in maintaining health and combating diseases.
