Innate immune system acts as chemical or physical barrier, produce cytokines, activates compliment cascade, removes foreign substance and antigen presentation.

Adaptive immune system has two specific cell types known as B-cells and T-cells. This system works by antigen presentation, response generation and developing immunological memory.

Step 3

The lymphatic system which is a subpart of immune system works by draining proteins and excess fluids from all over the body to the bloodstream, removal of waste products produced by different cells of the body, fighting infections and transportation of fat-soluble vitamins and fats from digestive system to the bloodstream.
