Want this question answered?
The immune system consists of two parts: innate immunity and adaptive immunity. Innate immunity is the system of defense that every human is born with. It consists of the skin, protective secretions, the inflammatory response, andphagocytes. If microorganisms are able to penetrate the physical barriers (the skin and protective secretions), the body responds in a nonspecific way by increasing the blood flow to the area. This allows phagocytes to take action. Phagocytes are white blood cells that eliminate the chances of infection by attacking foreign substances in the body.
Phagocytes are comprised of fatty acids and proteins. They are cells used in the immune system to fight infections and bacteria.
Lysozymes
Most are found circulating through the body as parts of the immune system, but a few of the tissues that have their own dedicated phagocytes that are not immune cell are Skin, Blood vessels, Connective tissue, and Blood.

phagocytes chew the cells up and the immune system in general notice it.
By presenting small pieces of the organism on their surface.
well...phagocytes are mainly part of the immune systems defense system, like when there is an inflammatory response. While lymphocytes are mainly for when the immune system attacks a foreign organism. However, lymphocytes can become phagocytes that's why i didnt say that they were part of a certain sector of the immune system.
Microbes evade the immune system through inhibition of phagocytosis by affecting the receptors that phagocytes use to engulf bacteria or by mimicking host cells so that the immune system does not recognize them as foreign.
