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.
Fluid later passes from the distal tubule to the collecting ducts. Ultra filtration occurs in the cortex in the cortical collecting ducts, which is the last process of the nephron. The urine then passes through the collecting ducts through the drainage system of the kidney to the ureters and bladder for urination.T he counter current system is similar to the nephron because the loop of henle is to be able to create dilute urine or concentrated urine depending on what the body wants and needs.he urine then passes through the collecting ducts through the drainage system of the kidney to the ureters and bladder for urination.
