Study Notes
Blood Brain Barrier
- The blood brain barrier (BBB) is a selective barrier that restricts the passage of substances into the brain.
Purpose of the Blood Brain Barrier
- The primary purpose of the BBB is to protect the brain from harmful substances in the blood while allowing essential nutrients to pass through.
Substances Limited by the Blood Brain Barrier
- The BBB restricts the passage of large molecules, toxins, and certain medications to prevent them from entering the brain.
- These substances are limited due to their molecular size, charge, and lipid solubility.
Substances that Freely Pass Through the Blood Brain Barrier
- Small lipophilic (fat-soluble) molecules, such as oxygen and carbon dioxide, can freely pass through the BBB.
- Certain nutrients, like glucose and amino acids, can pass through the BBB through facilitated diffusion or active transport.
Inferences about the Blood Brain Barrier
- The BBB is a dynamic and selective barrier that plays a crucial role in maintaining brain homeostasis and protecting the brain from potential toxins.
- Its selective permeability allows the brain to maintain a stable environment, which is essential for proper brain function.
