The following information is about Blood-brain barrier.
Blood-brain barrier Defined
The BBB has several important functions as protects the brain from "foreign substances" in the blood that may injure the brain, protects from hormones and neurotransmitters in the rest of the body and also maintains a constant environment for the brain. It is semi-permeable; that is, it allows some materials to cross, but prevents others from crossing. In most parts of the body, the smallest blood vessels, called capillaries, are lined with endothelial cells. The endothelial tissue has small spaces between each individual cell so substances can move readily between the inside and the outside of the vessel. However, in the brain, the endothelial cells fit tightly together and substances cannot pass out of the bloodstream.
