Blood-Brain Barrier prevent material from moving in or out of the brain's capillaries.

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.
  • Correct neuronal function is enabled by the careful regulation of CNS homeostasis, which also safeguards neural tissue from toxins and infections.
  • Alterations to these barrier qualities play a significant role in the pathophysiology and development of various neurological illnesses.
