What is the pathway of lymph?

The lymphatic capillaries conduct the fluid into larger lymphatic vessels, which carry it toward lymph nodes and lymphoid organs.

What is the order of lymph flow?

Flow of Lymph : The lymph flows from the afferent vessels into the sinuses of the lymph node, and then out of the node through the efferent vessels.

What is the flow of lymph?

The lymph flows into lymph nodes through afferent collecting lymphatic vessels and exits through efferent collecting lymphatic vessels. The lymph not only flows through the lymph node, but some of it is reabsorbed into the blood circulation at the lymph nodes.

How does lymph travel through the lymphatic system?

LYMPHATIC CIRCULATION

The lymph is moved through the body in its own vessels making a one-way journey from the interstitial spaces to the subclavian veins at the base of the neck. Since the lymphatic system does not have a heart to pump it, its upward movement depends on the motions of the muscle and joint pumps.

Where does lymph eventually go?

Collecting ducts: Lymphatic vessels empty the lymph into the right lymphatic duct and left lymphatic duct (also called the thoracic duct). These ducts connect to the subclavian vein, which returns lymph to your bloodstream.

What increases lymph flow?

Lymph flow depends, predominantly, on local pressure effects and intrinsic contraction of the larger lymphatics. Any factor that increases the interstitial tissue pressure by 2 mm Hg tends to increase lymph flow in lymphatic vessels. … The contraction of a lymphangion can generate a pressure as high as 25 mm Hg.

How is lymph formed?

Lymph originates from interstitial fluid that is formed where capillaries and body tissues exchange fluid and other substances. The lymph drains into lymphatic capillaries. The lymphatic capillaries conduct the fluid into larger lymphatic vessels, which carry it toward lymph nodes and lymphoid organs.

What is lymph and its function?

Lymph mainly contains white blood cells (mainly lymphocytes). Lymph carries digested and absorbed fat from intestine and drains excess fluid from extracellular space back into blood. Lymph supplies mature lymphocytes to the blood. Lymph acts to remove bacteria and other particles. It also maintains fluid balance.

How does lymph keep us healthy?

The lymphatic system helps defend the body against illness-causing germs, bacteria, viruses and fungi. The system builds immunity by making special white blood cells (called lymphocytes) that produce antibodies which are responsible for immune responses that defend the body against disease.
