Amaryl 1 mg price in india Participation эффекторов in temperature regulation levitra The filtration of water and low-molecular components from blood plasma in a capsule cavity occurs through клубочковый, or гломерулярный, the filter. The glomeruljarnyj filter has 3 layers: эндотелиальные cages of capillaries, базальную a membrane and эпителий висцерального a capsule leaf, or подоциты. Эндотелий capillaries has a time in diameter of 50-100 nanometers that limits passage of uniform elements of blood (эритроцитов, leukocytes, тромбоцитов). The basic barrier to a filtration is базальная the membrane. A time in базальной to a membrane makes 3 - 7,5 nanometers. This time from within contains negatively charged molecules (анионные loci) that interferes with penetration of negatively charged particles, including fibers. The third layer of the filter is formed by shoots подоцитов between which there are slot-hole diaphragms which limit passage альбуминов and other molecules with the big molecular weight. This part of the filter also bears a negative charge. Substances смолекулярной by weight no more than 5500 can easily be filtered, an absolute limit for passage of particles through the filter in norm is the molecular weight 80 000. Thus, the structure первичноймочи is caused by properties гломерулярного the filter. In norm together with water all low-molecular substances, behind an exception большей parts of fibers and uniform elements of blood are filtered. In the rest the ultrafiltrate structure is close to blood plasma.
