Innate immunity is found in both animals with and without adaptive immunity. The molecular components of the innate immune system do not appear to be closely related to the molecules of the adaptive system.
Our immune system is a complicated network of cells, tissues, and organs to keep us healthy and fight off disease and infection. The immune system is composed of two major parts: the innate immune system and the adaptive immune system.Both change as people get older. Studies to better understand these changes may lead to ways of supporting the aging immune system. Innate immunity is our first line of defense.It is made up of barriers and certain cells that keep harmful germs from entering the body. These include our skin, the cough reflex, mucous membranes, and stomach acid.ur immune system is a complicated network of cells, tissues, and organs to keep us healthy and fight off disease and infection.
