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.
Im really confused as to where in the nephron of the kidney each of the three steps of urine formation occur the steps include: 1. glomerular filtration 2. tubular reabsorption 3.tubular secretion does glomerular filtration occur in the renal corpuscle, then the tubular reabsorption occur in the proximal...ubular secretions: It is the mechanism by which substances are removed from the blood and are directly added to the tubular fluids. Hydrogen ion, ammonium and drugs such as penicillin are some of the substances that move from the blood into the distal tubule of nephron.
