PATHOLOGY

Detailed explanation-1: -There are five types of white blood cells: Neutrophils: Help protect your body from infections by killing bacteria, fungi and foreign debris. Lymphocytes: Consist of T cells, natural killer cells and B cells to protect against viral infections and produce proteins to help you fight infection (antibodies).

Detailed explanation-2: -White blood cells move through blood and tissue throughout your body, looking for foreign invaders (microbes) such as bacteria, viruses, parasites and fungi. When they find them, they launch an immune attack.

Detailed explanation-3: -They create antibodies to fight against bacteria, viruses, and other potentially harmful invaders.

Detailed explanation-4: -The bone marrow continuously produces white blood cells. They are stored within the blood and lymphatic systems until they are necessary for fighting an infection or disease in the body.
