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 innate immune system is inherited. It is active from the moment your child is born. When this system recognizes an invader, it goes into action right away. The cells of this immune system surround and cover the invader.

Detailed explanation-3: -Immunity that is present at birth and lasts a person’s entire life. Innate immunity is the first response of the body’s immune system to a harmful foreign substance. When foreign substances, such as bacteria or viruses, enter the body, certain cells in the immune system can quickly respond and try to destroy them.

Detailed explanation-4: -The nonspecific immunity or innate immunity is a type of non-specific immunity present at birth, or in people whose immune systems are not yet fully developed, and therefore, it is not able to provide specific and selective pathogens.
