Blood barriers in the body include the blood-brain barrier and the blood-testis barrier. These barriers act as selective filters that protect sensitive tissues from harmful substances in the bloodstream, while still allowing the passage of necessary nutrients.

FAQs & Answers

  1. What is the function of the blood-brain barrier? The blood-brain barrier protects the brain by preventing harmful substances in the bloodstream from entering neural tissue, while allowing essential nutrients to pass.
  2. How do blood barriers affect medication delivery? Certain blood barriers can limit the effectiveness of medications, as many drugs cannot cross these filters to reach target tissues.
  3. What are some diseases associated with blood barrier dysfunction? Diseases such as multiple sclerosis and Alzheimer's disease can arise from dysfunctions in the blood-brain barrier.
  4. How are blood barriers formed? Blood barriers are formed by specialized cells that create tight junctions, controlling the passage of substances between the blood and surrounding tissues.
