1. Protection: The BBB (Blood-Brain Barrier) shields the brain from harmful substances and toxins in the bloodstream. 2. Regulation: It maintains the brain's microenvironment by regulating the entry and exit of nutrients and waste products. 3. Facilitation: The BBB facilitates the transport of essential molecules such as glucose and amino acids that are crucial for brain function.

FAQs & Answers

  1. What is the Blood-Brain Barrier? The Blood-Brain Barrier (BBB) is a protective barrier that helps maintain the brain's environment by controlling what substances can enter.
  2. How does the BBB protect the brain? The BBB protects the brain by preventing harmful toxins and pathogens in the bloodstream from entering the brain.
  3. Why is the regulation function of the BBB important? Regulation by the BBB is crucial for maintaining the right balance of nutrients and waste, ensuring optimal brain function.
