Eviction seems harsh, but itâs the business of rental properties. If a tenant canât pay, you have to remove them from your property. Sometimes, itâs as simple as asking them to leave. Other times, you will have to go through the formal eviction process. Regardless of the situation, before starting the eviction process, you need to know the proper rules and procedures.
The blood-brain barrier (BBB) is a diffusion barrier, which impedes influx of most compounds from blood to brain. Three cellular elements of the brain microvasculature compose the BBB-endothelial cells, astrocyte end-feet, and pericytes (PCs).Tight junctions (TJs), present between the cerebral endothelial cells, form a diffusion barrier, which selectively excludes most blood-borne substances from entering the brain.hree cellular elements of the brain microvasculature compose the BBB-endothelial cells, astrocyte end-feet, and pericytes (PCs).

The answer is because of the blood-brain barrier. This layer of cells keeps your brain safe from pathogens and other toxins. It is composed of brain cells and blood vessel cells. It plays a crucial role in protecting the most important organ in your body: the brain. The blood-brain barrier is like the moat outside a castle, preventing harmful invaders from entering.
