Lymph is plasma-like fluid containing white blood cells.

The lymphatic system is composed of lymph vessels, lymph nodes, and organs. The functions of this system include the absorbtion of excess fluid and its return to the blood stream, absorption of fat (in the villi of the small intestine) and the immune system function.

Lymph vessels are closely associated with the circulatory system vessels. Larger lymph vessels are similar to veins. Lymph capillaries are scatted throughout the body. Contraction of skeletal muscle causes movement of the lymph fluid through valves.

Lymph organs include the bone marrow, lymph nodes, spleen, and thymus. Bone marrow contains tissue that produces lymphocytes. B-lymphocytes (B-cells) mature in the bone marrow. T-lymphocytes (T-cells) mature in the thymus gland. Other blood cells such as monocytes and leukocytes are produced in the bone marrow. Lymph nodes are areas of concentrated lymphocytes and macrophages along the lymphatic veins. The spleen is similar to the lymph node except that it is larger and filled with blood. The spleen serves as a reservoir for blood, and filters or purifies the blood and lymph fluid that flows through it. If the spleen is damaged or removed, the individual is more susceptible to infections. The thymus secretes a hormone, thymosin, that causes pre-T-cells to mature (in the thymus) into T-cells.

Lymph is the fluid that flows through the lymphatic vessels. The lymphatic system is part of the general circulatory system, which consists of L. vessels and organs. It's function is to take up excess tissue fluid and return it to the bloodstream-preventing edema- and of course it's over all goal to protect the body against disease, through the immune response. Furthermore lymph is picked up as tissue fluid at the start of lymphatic capillaries, which join larger vessels.

The word lymph is derived from the name of the Roman deity of fresh water, Lympha . Lymph is the fluid that circulates throughout the lymphatic system . Lymph has a composition comparable to that of blood plasma, but it may differ slightly. Lymph contains white blood cells. In particular the lymph that leaves a lymph node is richer in lymphocytes. Likewise, the lymph formed in the human digestive system called chyle is rich in triglycerides (fat), and looks milky white.

plasma-like fluid containing white blood cells

Lymphatic system
The lymphatic system is a complex network of lymphoid organs, lymph nodes, lymph ducts, and lymph vessels that produce and transport lymph fluid from tissues to the circulatory system. The lymphatic system is a major component of the immune system.
The lymphatic system has three interrelated functions:
(1) removal of excess fluids from body tissues
(2) absorption of fatty acids and subsequent transport of fat, chyle, to the circulatory system and
(3) production of immune cells (such as lymphocytes, monocytes, and antibody producing cells called plasma cells

blood vesseles has pressure due to this pressure some fluid from the bloodstream seeps out as extracellular fluid.
then to avoid the loss caused by escaping of this fluid the escaped fluid is absorbed back to blood by another system of vesseles called lymphatic vesseles. and this fluid which is reabsorbed , running in lymphatic vesseles is called LYMPH.
the seeping out and reabsorption of lymhp has advantages.because it carries lipid molecules absorbed by small intestine.these lipid molecules may not be transported simply by bloodstreram because of there large size so these lipid molecules are transported by lymph.
lymph also transport foreign particles & cellular debris.lymph also caries lymphatic cells which help in defnce.

Lymph nodes make up your lymphatic system.These nodes are under your armpits,in your groin etc and help fight infection etc
