Lymphatic+System


 * Lymphatic system**

Take excess fluid from tissues and return it to bloodstream. Lymphocytes, cells of lymphatic system, launch attacks on foreign particles in the body.
 * Functions:**

a. Circulation (take fluid and carry it through bloodstream) b. Absorption (absorb fat in small intestine) c. Digestion (absorb fat and get rid of it)
 * Characteristics of Life:**
 * could have explained the digestion connection better, as this is not obvious. Otherwise, very thorough wiki page! ~Mrs. Rohland **

a. Integumentary System: skin act as the first line of defense for immune system b. Nervous System: stress may impair immune system c. SkeletalSystem: cells of immune system originate from the bone marrow
 * System interactions with other system:**

The lymphatic system carry waste product from metabolism by bloodstream to place where the waste would be eliminate.
 * Metabolisms:**

Lymphatic system takes excess fluid and return it to the bloodstream to keep the fluid from accumulate in interstitial spaces in most tissues.
 * Homeostasis:**
