Phagocytes are a type of white blood cell, specifically neutrophils and macrophages, that are responsible for engulfing and destroying foreign invaders like bacteria, viruses, and fungi. This process is called phagocytosis.
Here's a breakdown:
* Neutrophils: These are the most abundant type of white blood cell and are the first responders to infection. They quickly migrate to the site of infection and engulf and destroy bacteria.
* Macrophages: These are larger than neutrophils and are long-lived. They patrol the body for foreign invaders and engulf and destroy them, as well as cleaning up debris from damaged tissues.
Both neutrophils and macrophages use a variety of mechanisms to destroy the bacteria they engulf, including enzymes and reactive oxygen species.
