The lymphatic vessels drain excess tissue fluid, prevent edema, and remove cellular debris and pathogens. The immune system monitors all organ and provides defense against pathogen. Natural killer cells patrol the body and provide immune surveillance against cancer. All systems are subject to a variety of hypersensitivity and autoimmune disorders. Describe in detail the immune system, hypersensitivity and autoimmune disorders for the circulatory system, integumentary system, respiratory system, urinary system, digestive, reproductive system, endocrine system, nervous system, muscular system, and the skeletal system. Select only 3 systems.

Answer 1
