Human Lymphatic System
The lymphatic system (right click to zoom in)
Fluid between cells, leaked from the capillaries, is returned to the blood
system via lymph capillaries and vessels which make up the lymph system.
Pathogenic organisms and cell debris are mixed with the fluid, which is
called "lymph", when it is in the lymph vessels. The lymph passes to the
lymph nodes and then along vessels to ducts which link with the blood
system at the neck. A red line along an arm or leg often indicates the
progress of an infection.
