The efferent vessels that bring lymph from the lymphatic organs to the nodes bringing the lymph to the right lymphatic duct or the thoracic duct, the largest lymph vessel in the body. These vessels drain into the right and left subclavian veins , respectively.
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 system, or lymphoid system, is an organ system in vertebrates that is part of the immune system and complementary to the circulatory system.It consists of a large network of lymphatic vessels, lymph nodes, lymphoid organs, lymphatic tissue and lymph.
The lymph transport, in the thoracic duct, is mainly caused by the action of breathing, aided by the duct's smooth muscle and by internal valves which prevent the lymph from flowing back down again. There are also two valves at the junction of the duct with the left subclavian vein, to prevent the flow of venous blood into the duct.
Lymph that enters the lymph vessels from the interstitial spaces usually does not flow backwards along the vessels because of the presence of valves. If excessive hydrostatic pressure develops within the lymph vessels, though, some fluid can leak back into the interstitial spaces and contribute to formation of edema .
Lymphatic vessels carry lymph, a colorless, watery fluid originating from interstitial fluid (fluid in the tissues) which is squeezed out of the blood vessels. The lymphatic system transports infection-fighting cells called lymphocytes , is involved in the removal of foreign matter and cell debris by phagocytes and is part of the body's immune ...
Propulsion of lymph from one lymphangion to next. A lymphangion is the functional unit of a lymph vessel that lies between two semilunar (half moon-shaped) valves. [1] [2]Lymph vessels are channels larger than the lymph capillaries that have thicker walls, valves in their lumen and smooth muscles in their walls, thus lymph vessel lymphangion is muscular and capable of contracting on its own.
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 .
