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. About 20% of the plasma volume passing through the glomerulus at any given time is filtered.
Filtration is driven by the hydrostatic pressure of the blood, and causeswater and small molecules to be filtered, while blood cells and large molecules like proteins do not pass through the filter. Source [10]. In reabsorption & secretion, as the filtrate passes down the nephron most of it is reabsorbed into the blood.elieve it or not, the human kidney is capable of such a feat. The kidney is an amazing filtration device in that they can be used continuously for the duration of a human life without becoming clogged.
