The blood-brain barrier is a protective barrier that separates the brain and central nervous system from the bloodstream. It is made up of tightly packed cells that line the walls of the brain's blood vessels and restrict the passage of certain substances, such as toxins, pathogens, and large molecules, from entering the brain. This barrier helps to maintain the brain's delicate balance and protect it from harm.
