IMMUNOLOGY

Detailed explanation-1: -Immunoglobulins: These highly specialized protein molecules, also known as antibodies, fit foreign antigens, such as polio, like a lock and key. Their variety is so extensive that they can be produced to match almost all possible microorganisms in our environment.

Detailed explanation-2: -IgG antibodies help protect your body from viral and bacterial infections. Found in your blood and lymph system, IgM antibodies act as the first line of defense against infections. They also play a large role in immune regulation.

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: -Immunoglobulin molecules are composed of two types of protein chain: heavy chains and light chains.
