THE
LYMPHATIC
SYSTEM
, Overview of the
Lymphatic System
The lymphatic system is a complex network of cells, fluids, vessels, organs,
and glands that work together. It plays a crucial role in the body by aiding in
the circulation of bodily fluids, closely connected to the cardiovascular system.
The system serves three main functions: returning interstitial fluid to the
bloodstream, absorbing lipids, and defending against diseases. The immune
system is closely associated with the lymphatic system because the cells
within the lymphatic system not only provide protection against diseases but
also confer immunity against future infections.
