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.

Glomerular Filtration. The first step in renal processing involves the filtration of plasma in the glomerulus. Glomerular filtration is a process of bulk flow: water and low molecular weight substances move from the lumen of the capillary, across the filtration membrane, and into Bowman s space.lomerular filtration is a process of bulk flow: water and low molecular weight substances move from the lumen of the capillary, across the filtration membrane, and into Bowman s space.
