The lymphatic system. What is and what do?
In: Biology
The lymphatic system is a network of vessels and organs that (among other things) help maintain your body’s fluid levels and serves as part of our immune system.
As our blood circulates through our bodies, most of the plasma and other fluids it contains remains in the blood vessels but some of it seeps into our tissues. The lymphatic system collects this fluid, now called lymph, and ultimately gets it back into our bloodstream.
The lymphatic system is also responsible for creating and transporting lymphocytes, a type of white blood cell, and other immune cells. When bacteria, viruses or other foreign bodies pass through the lymphatic system, they get sort of filtered out and collected at the lymph nodes; when we have an infection, more of those germs are collected in the nodes and more blood goes to the area to try to eliminate the infection, causing the nodes to swell up.
