Lymphatic system is the transport system that is primarily responsible for the return of intercellular proteins to the bloodstream. The lymphatic system is essentially a network of vessels designed to transport waste of cell metabolism back into the venous system. In this network, at specific points, glands are inserted in order to filter the lymph fluid

The most important functions of the lymphatic system are:

• The return of proteins which are present in the intercellular space with endogenous and exogenous origin.
• Compensation of the intercellular fluid charge when balance is disturbed
• Disposal of toxic and infectious substances by their storage or detoxification in the local lymph nodes
• Immunity regulation through protein transfer from the intercellular space to the local lymph nodes for the production of antigens
