IMMUNOLOGY

Detailed explanation-1: -White blood cells are the key players in your immune system. They are made in your bone marrow and are part of the lymphatic system. White blood cells move through blood and tissue throughout your body, looking for foreign invaders (microbes) such as bacteria, viruses, parasites and fungi.

Detailed explanation-2: -White blood cells are part of the body’s immune system. They help the body fight infection and other diseases.

Detailed explanation-3: -The immune system is made up of two parts: the innate, (general) immune system and the adaptive (specialized) immune system. These two systems work closely together and take on different tasks.

Detailed explanation-4: -What do white blood cells look like? Contrary to their name, white blood cells are colorless but can appear as a very light purple to pink color when examined under a microscope and colored with dye. These extremely tiny cells have a round shape with a distinct center membrane (nucleus).

Detailed explanation-5: -Stem cells in the bone marrow are responsible for producing white blood cells. The bone marrow then stores an estimated 80–90% of white blood cells. When an infection or inflammatory condition occurs, the body releases white blood cells to help fight the infection.
