MICROANATOMY

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: -The acquired immune system, with help from the innate system, makes special proteins (called antibodies) to protect your body from a specific invader. These antibodies are developed by cells called B lymphocytes after the body has been exposed to the invader.

Detailed explanation-3: -Antibodies are protective proteins produced by your immune system. They attach to antigens (foreign substances)-such as bacteria, fungi, viruses and toxins-and remove them from your body.

Detailed explanation-4: -Immunoglobulin or Immune Globulin: An antibody. A protein produced by the immune system in response to a foreign substance such as a virus or bacterium. The term “gamma globulin” is also used to refer to some immunoglobulins.

Detailed explanation-5: -White blood cells, also called leukocytes (LOO-kuh-sytes), play an important role in the immune system. 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.
