ANATOMY

Detailed explanation-1: -Some types of white blood cells, called phagocytes (pronounced: FAH-guh-sytes), chew up invading organisms. Others, called lymphocytes (pronounced: LIM-fuh-sytes), help the body remember the invaders and destroy them. One type of phagocyte is the neutrophil (pronounced: NOO-truh-fil), which fights bacteria.

Detailed explanation-3: -A type of immune cell that can surround and kill microorganisms, ingest foreign material, and remove dead cells. It can also boost immune responses. Monocytes, macrophages, and neutrophils are phagocytes.

Detailed explanation-4: -Neutrophils are the most important circulating phagocyte, providing the first line of defense against invading particles, especially bacteria. Circulating monocytes, precursors to tissue macrophages, also have the ability to phagocytize.

Detailed explanation-5: -Phagocytes surround any pathogens in the blood and engulf them. They are attracted to pathogens and bind to them. The phagocytes membrane surrounds the pathogen and enzymes found inside the cell break down the pathogen in order to destroy it.
