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.
List and describe the functions of the kidneys. NEPHRONS. Describe the two major portions of a nephron and the capillaries that surround a nephron. In the order that fluid passes through them, list the three main sections of the renal tubule.Distinguish between cortical and juxtamedullary nephrons.escribe three major functions carried out by nephrons and where each of these processes occurs. Describe the parts of the filtration membrane and explain which parts do not allow which substances to go through. List and name the forces that contribute to net filtration pressure (NFP) and explain how NFP is calculated.
