1. Body Systems
Lymphatic

2. Function
A network of vessels, nodes and organs which collect interstitial fluid lost by the blood and returns it back to circulatory system.
(we loose more than 3 liters a day)
One Way System
Filters bacteria and microorganisms
Help maintain movement of nutrients and salts through tissues
Absorb fat and fat-soluble vitamins from small intestines
Helps to produce and transports white blood cells

3. Contributing Organs
(Structures dedicated to the production and circulation of lymphocytes, WBC)
Spleen- Synthesis antibodies and removes bacteria. Makes and holds RBC and recycles iron. (Can be considered like a large lymph node)
Thymus-Produce T cells (for the immune system)
Bone Marrow –produces white blood cells

4. Movement
Lymph is moved through vessels by contractions of skeletal muscles and pressure gradient
Vessels have one way valves that prevent back flow
Lymph returns to the
circulatory system
through the superior
Vena Cava

5. Diseases
Lymphadema- Swelling of the lymph nodes because accumulation of fluid, caused by damage or malformation to the nodes
Lymphoma- a cancer that originates in the lymph nodes
