ANATOMY

Detailed explanation-1: -Innate immunity: Everyone is born with innate (or natural) immunity, a type of general protection. For example, the skin acts as a barrier to block germs from entering the body. And the immune system recognizes when certain invaders are foreign and could be dangerous.

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: -The innate immune system is the body’s first line of defense against germs entering the body. It responds in the same way to all germs and foreign substances, which is why it is sometimes referred to as the “nonspecific” immune system.

Detailed explanation-4: -Types of immunity: Active natural: Body produces antibodies in response to exposure to a live pathogen. Active artificial: Body produces antibodies in response to a vaccine. Passive natural: Antibodies are passed from the mom to her baby through the placenta and breastmilk.
