ANATOMY

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

Detailed explanation-2: -Types of white blood cells are granulocytes (neutrophils, eosinophils, and basophils), monocytes, and lymphocytes (T cells and B cells). Checking the number of white blood cells in the blood is usually part of a complete blood cell (CBC) test.

Detailed explanation-3: -The two main types of lymphocytes are B lymphocytes and T lymphocytes. B lymphocytes make antibodies, and T lymphocytes help kill tumor cells and help control immune responses. A lymphocyte is a type of white blood cell.

Detailed explanation-4: -The main difference between lymphocytes and phagocytes is that lymphocytes generate specific immune responses against pathogens whereas phagocytes generate the same response to any pathogen. This means lymphocytes are the tools of the adaptive immunity whereas phagocytes are the tools of innate immunity.

Detailed explanation-5: -Monocytes, macrophages, and neutrophils are phagocytes. A phagocyte is a type of white blood cell.
