Gotta love A&P ..haha
The lymph node is a filter so cellular debris, suspended bacteria, other particulates would be removed.
(from Yahoo)
The flow of lymph is slow because the lymphatic system has no pump.
Fatty acids and glycerol are absorbed in the ileum. Fat enters the lacteals of villi, which empty the lacteals into the lymph vessels. Transport of fat in lymph may reduce risk of plaque arteries.
It's from tissue fluid, which itself is derived from cappillaries
As the lymph is entering the lymph node, there are many pathways that it may encounter, whether it be to subcapsular sinuses, trabecular sinuses, or medullary sinuses. The fibers are present in the lymph nodes in order to control and regulate the direction of the lymph through the node. Someone else said: They wrap around the collagen so that they wont be exposed.
Blockage of and lymph vessel is keeping the fluids (usually blood, blood that is in need of cleaning) from entering the lymph node. This blockage causes additional blood that needs to be delivered to the lymph node for filtering to back up, kind of waiting for it's turn. This back-up of blood, (and sometimes other fluids), is what causes the swelling.
Lymph is actually plasma without plasma proteins. Lymph is formed when plasma oozes out of the minute pores of the capillaries. Since plasma proteins are too large to go through the pore, lymph is devoid of any plasma proteins.
One study found that only 2.6% of patients who had SLNB developed lymphedema, compared to 27% of patients who had ALND.
Lymph returns to the circulatory system by entering large veins near the heart.
Lymph is a fluid. It flows through the lymphatic vessels by one way valves which allows lymph move way through lymphatic system. Subclavian suction, and skeletal muscle pumps help to propel the lymph through the lymphatic vessels.
tiny vessels
How does the lymphatic system protect the body against pathogens?
The lymph nodes filter lymph.
