leukocyte

Leukocytes, commonly known as white blood cells, are a crucial component of the immune system in vertebrates, including humans. These cells are responsible for defending the body against infections and foreign substances. Leukocytes are produced in the bone marrow and circulate throughout the bloodstream and lymphatic system, where they detect and respond to pathogens, toxins, and other harmful agents.

There are several types of leukocytes, each with specific functions in immune defense:

Neutrophils: Phagocytize pathogens and release enzymes to destroy them.

Lymphocytes: Include T cells, B cells, and natural killer cells; they play key roles in adaptive immunity, including antibody production and targeted killing of infected or abnormal cells.

Monocytes: Transform into macrophages in tissues, where they engulf and digest pathogens and cellular debris.

Eosinophils: Involved in combating parasitic infections and allergic reactions.

Basophils: Release histamine and other chemicals during inflammatory responses.

Leukocytes are vital for maintaining health and protecting the body from a wide range of diseases and infections.
