What is blood-brain barrier?
- All of the body's tissues and organs depend on blood arteries to carry oxygen and nutrients to them.
- The blood-brain barrier, a special property of the blood arteries that vascularize the central nervous system (CNS), enables these vessels to tightly control the transit of ions, chemicals, and cells between the blood and the brain.
