Lymphatic system

What is Lymphatic system?

Lymphatic system meaning The lymphatic system (with the cardiovascular system) provide the internal environment of the body. The blood carries food and oxygen to, and waste products from, the cells of the body. The lymphatic system consists of a set of vessels and aggregations of lymphatic tissue which collect and carry lymph from the body tissues to the veins of the blood circulatory system.Lymph vessels, like blood vessels, are distributed to nearly all parts of the body. The lymphatic system carries fluid away from, and not to the tissues; consequently, it is not a continuous closed circulation system as is the cardiovascular system. The lymph enters the system via the lymph capillaries and flows into larger and larger collecting vessels until it finally empties into the subclavian veins. Interposed along the lymphatics (lymph vessels) are many lymph nodes, structures which serves as filters to clear the lymph or particulate matter. Lymphatic organs and tissues include lymph nodes, the spleen, thymus, tonsils, and Peyer's patches of the small intestines. The lymph nodes, spleen, and thymus have roles as hematopoietic (lymphopoietic) centers mainly producing lymphocytes.
