Lymphatic system
The lymphatic system is the lesser known circulatory system of the body. Excess tissue fluid and cell waste, called the lymph, travels in this system of vessels similar to how the blood travels in the veins. This system filters the tissue fluid and is part of the body's immune defenses. Along the lymphatic vessels are lymph nodes, areas where immune cells survey the proteins and material being transported from cells. When a person is exposed to a bacteria or virus, they may experience a swollen lymph node where the pathogen is being confronted and fought by the immune cells. Also a part of this system are lymphatic tissues that are rich in immune cells. Well known lymphatic tissues are the tonsils and spleen. If the lymphatic system becomes obstructed, the result is lymphedema - a swelling of the tissue surrounding the blocked vessels.

Spleen: Soft fist-sized organ above the stomach and behind the ribs, can be surgically removed if damaged or ruptured. Thymus: Located at the base of the neck, active organ in newborns to process T cell development, decreases in size over first few years of life and appears to have no major function in adults. Peyer's patches: One of the gut-assocated lymphoid tissues (MALT), filters potential pathogens from food in the intestines Lymph nodes: Located along the lymphatic vessels, filter and survey material draining from the cells and blood, they are found near points of entry (sentinels) - armpits, throat and neck, groin, and the trunk near major blood vessels
