What Is The Blood-Brain Barrier and Why Is It Important?

Your brain does a lot of hard work to keep it in excellent condition. It utilizes 20 percent of your body’s energy and demands an environment that’s exceedingly specific to sustain itself. Your brain requires your body deliver oxygen and nutrients while keeping it safe from any damaging molecules.

And the oxygen and nutrients are delivered to your mind the same way your body delivers it to your other organs: through your blood. This is why there are a lot of blood vessels surrounding your brain, and they’re very special. These blood vessels form the “blood-brain barrier.” Let’s dive in and learn what makes the blood-brain barrier so important.   

What is the Blood Brain Barrier?

The blood-brain barrier is a barricade of cells that chains your capillary endings, which deliver blood, to your central nervous system and brain. Semi-absorbent in nature, your blood-brain barrier prevents big molecules and damaging substances in your bloodstream from reaching your cerebrospinal fluid. However, things such as molecules of oxygen and ions, water, carbon dioxide, and alcohol can cross your blood-brain barrier.

Why is Your Blood-Brain Barrier So Important?

The blood-brain barrier has a critical permeability. It allows the transit of some little molecules and prevents the entry of massive particles. Thus, it acts as a strainer between your blood system and nervous system.

The waterproof function is conveyed by two processes: chemical and physical. The physical process is the physical act of straining. For this, there are areas in the middle of your cells that prevent and allow passage of any substance that tries to enter your brain.

Simultaneously, your blood-brain barrier has the ability to trigger particular chemical responses, metabolizing a number of substances that come in contact with it. This is the second process: a chemical strainer of sorts. Your blood brain barrier uses of enzymes and transporters and extinguishes any hazards before they enter your brain.

Aside from protecting your brain, your brain’s shield makes sure that your neuronal environment’s maintenance is just right. It protects the composition of your interstitial fluid, which cleanses any cells that compromise your brain.

Lastly, your blood-brain barrier executes metabolic functions, altering a number of elements so that they can travel from your blood to your nervous tissue without being damaged.

Your blood-brain barrier guarantees the optimal function of your brain. Your mind has an extraordinary power to treat and heal itself. However, just like other parts of your body, you need to make sure that you don’t neglect and abuse it. Do everything that you can to take good care of it.
