How does the immune system work? What cellular components make up the Immune System?

Neutrophils, eosinophils, basophils, monocytes, lymphocytes, natural killer cells, and macrophages make up the immune system’s cellular components.

This is Dr. Jim for Be Healthy! Be Happy! College of Immune Health – Immune Health 101: The Cellular Components.

The immune system functions as an integrated network of organs, specialized cells and unique bodily fluids. In this segment, I discuss the cellular components that make up this complex system.

The cellular components of the immune system are manufactured in the bone marrow. Specific bone marrow response and a cell line production depends upon the specific challenges presented to the system.

Neutrophils proliferate and ward off many kinds of infections, predominately bacterial.

Eosinophils fight parasites and respond in abundance to allergic reactions.

Basophils release a substance called histamine, which works effectively to mitigate allergic reactions.

Monocytes also fight infectious diseases, in particular, tuberculosis and parasite infestations.

Lymphocytes attack and destroy viruses. They also make antibodies based on memory acquired from prior infections.

Natural killer cells or NK cells, on the other hand, release chemical toxins that kill invading microorganisms.

Finally, macrophages work as scavengers to engulf and clear cellular debris produced during immune system function.
