The Lymphatic System

The Lymphatic system is an extensive, complex network of lymphatic vessels, lymph nodes, ducts, and lymphoid organs and tissues.  It extends to every part of the vertebrate body except the brain and spinal cord. 

The lymphatic system has three essential functions: drainage to help balance body fluids, absorption of fatty acids and fat-soluble nutrients in the stomach, and immune-system regulation.  It also complements the circulatory system (blood vessels and veins).

 

The circulatory system processes about 35 pints/20 liters of blood daily through capillary filtration that removes plasma from the blood.  As the blood circulates through the body, about 3 pints/500 ml of blood plasma seeps into tissues through the thin capillary walls.

 

Plasma is the transport medium for delivering nutrients to the cells.  Additionally, it expels waste products (e.g., urea, creatinine, bacteria, protein, salts, etc.) through the kidneys, liver, and lungs.  Plasma also distributes heat throughout the body and helps to maintain homeostasis.
