IMMUNOLOGY

Detailed explanation-1: -Acquired immunity makes your immune system stronger. Vaccines, for example, expose your immune system to small amounts of pathogens that won’t make you sick. Your immune system learns how to recognize those germs, so the next time it encounters them, your immune system will know how to naturally fight them off.

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. The antibodies stay in your child’s body.

Detailed explanation-3: -A type of immunity that develops when a person’s immune system responds to a foreign substance or microorganism, or that occurs after a person receives antibodies from another source. The two types of acquired immunity are adaptive and passive.

Detailed explanation-4: -Examples of innate immunity include: Cough reflex. Enzymes in tears and skin oils. Mucus, which traps bacteria and small particles.

Detailed explanation-5: -Acquired immunity is also called specific immunity because it tailors its attack to a specific antigen previously encountered. Its hallmarks are its ability to learn, adapt, and remember. Acquired immunity takes time to develop after first exposure to a new antigen.

Detailed explanation-6: -IgM predominates in the primary response, IgG in the secondary response. Most react at 37°C and are considered clinically significant. Examples include antibodies in the Kell, Rh, Duffy, and Kidd systems.
