Here's a breakdown:

* Phagocytes are a type of white blood cell that engulf and destroy harmful microorganisms like bacteria, viruses, and fungi.

* They do this through a process called phagocytosis.

There are two main types of phagocytes:

* Neutrophils: The most abundant type of white blood cell, they are the first responders to infection and quickly engulf and destroy bacteria.

* Macrophages: Larger and longer-lived than neutrophils, they patrol the body and engulf bacteria, dead cells, and cellular debris. They also play a crucial role in presenting antigens to other immune cells, initiating an immune response.
