Detailed explanation-1: -What is the immune system? Your immune system is a large network of organs, white blood cells, proteins (antibodies) and chemicals. This system works together to protect you from foreign invaders (bacteria, viruses, parasites, and fungi) that cause infection, illness and disease.

Detailed explanation-2: -Lymphocytes. They create antibodies to fight against bacteria, viruses, and other potentially harmful invaders.

Detailed explanation-3: -The process where these white blood cells surround, engulf, and destroy foreign substances is called phagocytosis, and the cells are collectively referred to as phagocytes.

Detailed explanation-4: -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-5: -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.
