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.
How and where does most reabsorption occur in a nephron? The proximal tubule is the site of most reabsorption via glucose transporters (reabsorb 100% of glucose in healthy individuals), approx. 65% Sodium and various other solutes a â¦ re also reabsorbed.eabsorption in a nephron occurs in the Loop of Henle Reabsorption has been addressed to substances which are absorbed back from the nerphrone back in to the blood(capillaries â¦).
