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.
Best Answer: ultra filtration and reabsorption in kidney is carried out by its functional unit called nephron. Ultra filtration occurs between the glomerulus and Bowman's capsule of nephron.The larger afferent arteriole than efferent arteriole speeds up the ultra filtration.ltrafiltration Selective Reabsorption Selective reabsorption occurs in the proximal convoluted tubule. This is the longest and widest part of the nephron. In this part over 80% of the filtrate is reabsorbed into the blood.
