- Adaptive This part of develops when the body is exposed to specific microbes or chemicals released by microbes. It’s the part that forms specific antibodies to recognize and fight against particular pathogens. The adaptive includes lymphocytes like B-cells and T-cells, as well as other cells and molecules.

How does work?
We live in a world surrounded by microbes, and our bodies are constantly in contact with bacteria, fungi, and viruses. Natural microflora exists on all bodily surfaces, in the digestive tract, mouth, nose, and other cavities. Usually, there is a balance between the harmful effects of foreign agents and the body’s defense mechanisms.
This balance can tip one way or the other, depending on the immune system’s. Ability to resist invasions from foreign agents and their aggressiveness. Sometimes fails, and the balance shifts in favor of the microbes, leading to illness.
The immune system functions as a defense system that activates. When the body detects the presence of harmful microorganisms such as bacteria, viruses, and parasites. Often, this results in symptoms of illness, such as fever and fatigue.
