How does fluid flow through the lymphatic system?
Furthermore, how does fluid flow through a lymph node? Lymph enters a lymph node through several afferent lymphatic vessels. It then passes through the cortex, paracortex and medulla of the node, and exits on the opposite side through a single efferent lymphatic vessel.
How do lymphatic vessels move forward?
Since there is no pump driving the flood of lymph and, in most cases, lymph is moving against the flow of gravity, there are certain mechanisms that assist with the forward flow of lymph. Surrounding skeletal muscle contraction compresses lymphatic vessels, thereby forcing the lymph within them to flow in a forward direction.
How does the lymphatic system work?
The lymphatic system permeates the entire tissue structure of the body in a one-way drainage network of vessels, ducts, nodes, lacteals, and lymphoid organs. Segments of lymph capillaries are divided by one-way valves and a spiral set of smooth muscles called lymphangions. This system moves fluid against gravity in a peristalsis-type undulation.
What is the path of lymph through the lymphatic system?
A small fraction of entering lymph flows deeper into the lymph node and enters the blood circulation through lymph node venules. The majority of lymph flows into efferent lymphatics and is eventually merging into the thoracic duct and is deposited into the subclavian vein after passing through a final lymphovenous valve.
