Here's a breakdown:

* Phagocytosis is the process of engulfing and destroying foreign particles like bacteria, viruses, and cellular debris.

* Phagocytes are the cells that perform phagocytosis.

There are different types of phagocytes in the immune system, including:

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

* Macrophages: Larger and longer-lived than neutrophils, they engulf pathogens and also present their antigens to other immune cells to activate the immune response.

* Dendritic cells: Found in tissues that are in contact with the external environment, they engulf pathogens and present their antigens to T cells, initiating the adaptive immune response.

So, all these cells are considered phagocytes due to their ability to engulf and destroy pathogens.
