Phyllite is a type of foliated metamorphic rock created from slate that is further metamorphosed so that very fine grained white mica achieves a preferred orientation.It is primarily composed of quartz, sericite mica, and chlorite.mong foliated metamorphic rocks, it represents a gradation in the degree of metamorphism between slate and schist. The minute crystals of graphite, sericite, or chlorite, or the translucent fine-grained white mica, impart a silky, sometimes golden sheen to the surfaces of cleavage, called phyllitic luster.
Processes of the Kidneys. Filtration. Filtration is the mass movement of water and solutes from plasma to the renal tubule that occurs in the renal corpuscle. About 20% of the plasma volume passing through the glomerulus at any given time is filtered.This means that about 180 liters of fluid are filtered by the kidneys every day.iltration is the mass movement of water and solutes from plasma to the renal tubule that occurs in the renal corpuscle.

F: Cortex. The cortex is the outer part of the kidney. This is where blood is filtered. We call this process âultra-filtrationâ or âhigh pressure filtrationâ because it only works if the blood entering the kidney in the renal artery is at high pressure.ere is a diagram of the kidney showing a nephron broken up into six parts. Each part has a specific function. You can click on a letter to find out what that part does. Here is a diagram of a nephron put back together again. You can click on a green or red area to find out what happens there.
