As the collecting lymph vessel accumulates lymph from more and more lymph capillaries along its length, it becomes larger and eventually becomes an afferent lymph vessel as it enters a lymphs node. The lymph percolates through the lymph node tissue and exits via an efferent lymph vessel .
In peripheral organs, lymphatic vessels are responsible for conducting lymph between different parts of the body. In general, lymphatic drainage is important for maintaining fluid homeostasis as well as providing a means for immune cells to traffic into draining lymph nodes from other parts of the body, allowing for immune surveillance of bodily tissues.
Upon entering the lumen of a lymphatic capillary, the collected fluid is known as lymph. Each lymphatic capillary carries lymph into a lymphatic vessel, which in turn connects to a lymph node, a small bean-shaped gland that filters and monitors the lymphatic fluid for infections. [1] Lymph is ultimately returned to the venous circulation.
The lymphatic vessels, also called lymph vessels, are thin-walled vessels that conduct lymph between different parts of the body. [39] They include the tubular vessels of the lymph capillaries, and the larger collecting vessels – the right lymphatic duct and the thoracic duct (the left lymphatic duct).
Lymph trunk is a collection of lymph vessels that carries lymph, and is formed by confluence of many efferent lymph vessels. It in turn drains into one of the two lymph ducts ( right lymph duct and the thoracic duct ).
Lymph has a composition similar but not identical to that of blood plasma. Lymph that leaves a lymph node is richer in lymphocytes than blood plasma is. The lymph formed in the human digestive system called chyle is rich in triglycerides (fat), and looks milky white because of its lipid content.
The lymphatic vessels merge to form each trunk, which typically drains into the venous system. The left bronchomediastinal lymph trunk often empties into the thoracic duct or directly into the venous angle, where the internal jugular and subclavian veins converge. Similarly, the right trunk may connect to the right lymphatic duct or end at the ...
A lymph duct is a great lymphatic vessel that empties lymph into one of the subclavian veins. There are two lymph ducts in the human body —the right lymphatic duct and the thoracic duct . The right lymphatic duct drains lymph from the right upper limb, right side of thorax and right halves of head and neck .
