Blood- brain barrier
It is formed by filtration of blood through the fenestrations of the choroidal capillaries in the choroid plexus. It is flows by the active transport of substances (Particularly sodium ions) across the choroid epithelium into the ventricle, water then flows passively across to maintain osmotic balance. It has also been shown that if the choroid plexus was removed the ventricles still produced substantial quantities of CSF, though less than normal. And is generally considered to be fluid movement from CNS capillaries into the parenchyma of the brain, and from there across the ependymal lining into the ventricle.

The filtration membrane in the nephron is formed by the fenestrated endothelium of the glomerular capillaries, the glomerular basement membrane, and the podocytes of the Bowman's capsule that wrap around the capillaries. These structures work together to selectively filter and prevent the passage of larger molecules like proteins into the urine while allowing smaller molecules to be filtered.
The Delicate Arch, located in Arches National Park in Utah, is a natural sandstone arch formed through the processes of erosion and weathering. Over millions of years, the softer rock layers surrounding the arch eroded away, leaving behind the more durable Entrada sandstone that forms the arch itself. The unique shape of the Delicate Arch is a result of differential erosion, where varying rates of erosion along different rock layers create the distinctive arch structure. The arch is constantly being shaped by natural forces such as wind and water, highlighting the ongoing geological processes at work in the park.
The strongest wall of the bony orbit is the medial wall, which is formed by the ethmoid bone and lacrimal bone. It provides protection to the delicate structures within the orbit, such as the eyeball and optic nerve.

The Delicate Arch was formed from wind and water erosion. The arch started out as a solid wall, then was eroded by the water and wind and it created a hole. As this continued for millions of years, the hole expanded and now we have The Delicate Arch.
