ANATOMY

Detailed explanation-1: -The immune system orchestrates a potent defense that consists of the production of specific antibody molecules and lymphocytes capable of reacting with and inactivating foreign agents, either directly or indirectly through the involvement of molecular and cellular inflammatory processes.

Detailed explanation-2: -Human immunodeficiency virus (HIV) is the virus that causes acquired immune deficiency syndrome (AIDS). HIV weakens your immune system by destroying your T-cells until you are unable to fight off even minor illnesses.

Detailed explanation-3: -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. The antibodies stay in your child’s body.

Detailed explanation-4: -Allergic reactions begin in your immune system. When a harmless substance such as dust, mold, or pollen is encountered by a person who is allergic to that substance, the immune system may over react by producing antibodies that “attack” the allergen.
