Photomicrograph of thin section of phyllite (in cross polarised light). 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.
This commonly occurs throughout the entire nephron system especially within the Glomerulous and Bowman's Capsule where water, nitrogenous wastes, glucose, amino acids, vitamins, minerals, bicarbonate ions and hormones.ccuring more commonly within the nephron system than filtration, this is a form of active transport which takes the the useful substances for the body from the tubules and places them back into the blood filled capillaries.
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.
