INTRODUCTION:-
The study of lymphatic system is called lymphatology.
The lymphatic system permeats the entire body.
It comprises a colourless fluid the lymph network of fine channels, the lymphatic capillaries, tubes of varied sizes, the lymphatic vessels and lymph nodes.

Lymph is a colourless, mobile, fluid connective tissue, that’s slowly drains into the lymphatic capillaries from the intercellular spaces.
It is now accepted that this flow is not entirely a passive drainage. The small lymphatic vessels undergo continual rhythmic contractions, the pumping action of which causes a slight negative pressure to develop. This pressure draws the tissue fluid into the lymphatic capillaries. The lymph is a clear transparent fluid. It consist s of two parts : a fluid matrix , the plasma , in which float amoeboid cells , the white blood corpuscles ,or leucocytes.
The lymph in the lymph capillaries lacks the leucocytes, but receives them as it passes through the lymph node.

As already mention the lymph differ from the blood in lacking red blood corpuscles , platelets and some plasma proteins and in having less calcium and phosphorus than the blood. it has the power of clothing like the blood.
