The inside of the eye, the brain, and the testes are parts of the body that are not directly exposed to the immune system. They are protected by barriers like the blood-brain barrier and the blood-testis barrier, which prevent direct contact with immune cells.
A stroke is a disruption of the blood supply causing death of parts of the brain. A stroke is known in medical terms as a cerebrovascular accident.

No. Nerves are not blood-filled. They are a bundle of fibers that carry information from parts of your body back to your brain, where your brain then processes that information.
The blood reaches the brain because of heart pumping. the heart is capable of supplying blood in all "1G" conditions to all parts depending upon requirement.
Technically,all of parts of the brain has fluid in it and on it. Without the fluid the brain would dry up and we would be unable to function it. Of course this liquid is the "ooze" that you can sometimes see on TV shows, and it is also blood that is circulating around the blood-brain barrier which keeps a large majority of blood out and it only allows a certain amount of fluid in or else our wonderful brains would drown.
The basilar artery is a key blood vessel in the brain that supplies blood to the brainstem and the posterior cerebral circulation. It arises from the merging of the two vertebral arteries and plays a crucial role in delivering oxygenated blood to various parts of the brain.
Increased blood flow to active parts of the brain, known as neurovascular coupling, ensures that these regions receive enough oxygen and nutrients to sustain their high activity. This process is regulated by signals from the active neurons, causing nearby blood vessels to dilate and allow more blood to flow to the area. It is essential for supporting brain function and maintaining neural health.
