Blood Brain Barrier, Animation 

and when we spn then suddenly stop, the continuing movement of these hairs after we have stopped makes us dizzy.

No one is an outsider when learning about our body 👍

Cause many amino acids like gab glutamate etc can act as neurotransmitters and so it doesn't pass on its own as it can disrupt the signals While glucose is necessary for metabolic activity and thus passes through bbb

That's part of my question: How is glucose readily absorb in the brain after carbohydrates are broken down in the mouth?

@@timothyblount7040 carbohydrates broken down into glucose...

@@timothyblount7040 GLUT1 transporters are embedded in the membrane compared to skeletal glut4 which translocates after the effects of insulin. so the BBB has a glucose transporter that doesn’t need hormone activation, it’s already there

Welcome, and thanks for the Super thanks!

Its the same here.

I think evolution makes more sense here, those who lacked a blood brain barrier are more likely to develop brain infections

He was so generous to develop prion disease, soo wonderful gift. Your selective worldview is not scientific

@@Alex-wg1mb The existence of diseases does not negate the existence of the Creator. We are now in a scientific video. There are some questions, such as why there are diseases and natural disasters, why there is evil in the world, that the science of philosophy can answer. For example, the presence of a failing student in a class containing 50 successful students does not mean that there is something wrong with the professor, nor does it mean that the professor does not exist... As I said before, I do not want to delve deeply into philosophy here. It is shameful for the human mind to believe that this whole system In his body and in the world he was found by pure stupid coincidence. Let us not forget that the disease that you mentioned is rare and not all creatures are afflicted with it. A person’s normal life is all healthy except for some periods when he is afflicted by a disease.

Childhood Dementia (Or every type of dementia basically), cancer, prion diseases, world starvation and slavery, wars, disabled people, etc. "God" is wonderful, indeed. (Please don't push your religious beliefs into science.)

Good

alcohol does

Alcohol do pass the barrier. Most psychiatrist drug also pass the barrier like benzodiazepine, antipsychotics, etc.

Most medicine can breach the barrier, ex. Benzodiazepine can breach barrier and interact with GABA receptors on the brain.

Just don’t take it 🤷🏼‍♀️

@@MrPokerblot Take what?

@@TheEDNC don’t take your meds sunshine. 😉

@@MrPokerblot Ok, I see you’re not very knowledgeable… but that’s okay.
