Q. What is the lymphatic system?
The lymphatic system is a network of specialized valved vessels that drain interstitial fluid (lymph), the lymphatic system is as well responsible for the transport of chylomicrons (vesicles that contain lipids) made after the absorption of fats by the intestinal epithelium.
In the way of the lymphatic vessels there are ganglial-like structures called lymph nodes that contain many cells of the immune system these cells filter impurities and destroy microorganisms and cellular wastes. The lymphatic vessels drain to two major lymphatic vessels, the right lymphatic duct and the thoracic duct, that in their turns drain into tributary veins of the superior vena cava.
