1. The innate and adaptive immune systems - InformedHealth.org - NCBI
Jul 30, 2020 · The innate immune system activates special immune system cells and proteins if germs get past the skin and mucous membranes and enter the body.
The immune system fights germs and foreign substances on the skin, in the tissues of the body and in bodily fluids such as blood. The immune system is made up of two parts: the innate, (general) immune system and the adaptive (specialized) immune system. These two systems work closely together and take on different tasks.
