Astrocytes

...  play different roles in the body. Here are some of the notable significances of the cells. Blood Brain Barrier Astrocytes form part of the blood brain barrier. The long processes combine with the endothelial cells to make a distinction from the circulating blood and the cerebrospinal fluid found in the brain. The barricade stops the entry of large molecular substances and allows only the  ...

Blood Brain Barrier

...  blood brain barrier serves as the brain’s protection from its environment. It separates the circulating blood from the cerebrospinal fluid. The endothelial cells in tight junction create the boundary between the two fluids. They are responsible in restricting the flow of substances in the area. The projections of the Astrocytes, called the astrocytic feet or the glia limitans, surround  ...

Lymph Fluid

...  It is here that the lymphactic capillaries are known as lacteals and will be used for the transportation of any products which have been generated by fat absorption away from the GI tract. The endothelial cells make up the inner walls of the capillaries, which are porous, absorbed fats, interstitial fluid, proteins, and microorganisms which are able to enter these capillaries without  ...
