Structure нефрона The major factor promoting process of a filtration, pressure of blood (hydrostatic) in capillaries of balls is. To the forces interfering a filtration, concerns онкотическое pressure of fibers of plasma of blood and pressure of a liquid in a cavity of a capsule of a ball, i.e. primary urine. Hence, effective filtrational pressure represents a difference between hydrostatic pressure of blood in capillaries and the sum онкотического pressure of plasma of blood and intranephritic pressure. Thus, filtrational pressure makes: 70 (30 + 20) = 20 mm hg coumadin pills Tsiliarnye muscles иннервируются parasympathetic fibres глазодвигательного a nerve. Introduction in eye M-holinolitika - atropine blocks excitation transfer to цилиарной to a muscle and breaks accommodation at examining of close located subjects. And on the contrary, introduction M-holinomimetikov - пилокарпина and эзерина promotes reduction цилиарной muscles and to accommodation process.
