Lymph returns proteins and excess interstitial fluid to the bloodstream. Lymph also transports fats from the digestive system (beginning in the lacteals) to the blood via chylomicrons. Bacteria may enter the lymph channels and be transported to lymph nodes, where the bacteria are destroyed. Metastatic cancer cells can also be transported via lymph.
A lymph node showing afferent and efferent lymphatic vessels Regional lymph nodes. A lymph node is an organized collection of lymphoid tissue, through which the lymph passes on its way back to the blood. Lymph nodes are located at intervals along the lymphatic system.
The lymph percolates through the lymph node tissue and exits via an efferent lymph vessel. An efferent lymph vessel may directly drain into one of the (right or thoracic) lymph ducts, or may empty into another lymph node as its afferent lymph vessel. [6] Both the lymph ducts return the lymph to the blood stream by emptying into the subclavian veins
The primary role of the bronchomediastinal lymph trunks is to transport lymph, which contains proteins, lipids, and immune cells such as lymphocytes, from the thoracic organs, including the lungs, heart, trachea, and esophagus, to the bloodstream. These trunks act as major conduits for lymph to reach larger lymphatic ducts or directly enter the ...
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.
The fluid spaces communicate with draining lymph nodes, although they do not have lining cells or structures of lymphatic channels. [7] Interstitial fluid entering the lymphatic system becomes lymph, which is transported through lymphatic vessels until it empties into the microcirculation and the venous system. [4]
Lungs and mediastinum (they can see lymph nodes) Heart and great vessels (they can see whether the heart is enlarged and if there are any aortic aneurysms, but MRIs don’t show blockages or ...
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 ).
