Document Summary
Filtration slits : proteins , negatively charged. H2o , 10ns , aco 5, glucose tiny , tiny proteins. Scattered among endothelium of glomerulus afferent x mes ang lat cells glomerulus . 4 changes surface area of glomerulus for filtration. Similar to filtration in systemic capillaries filtration occurs , no reabsorption except 0h14. Hydrostatic bp in glomerular capillaries favors filtration. "too = on cona osmotic pressure due to blood proteins opposes filtration. Pbs = hydrostatic pressure in bowman is space. Tips = osmotic pressure due to proteins in filtrate. Poc is affected by the amt of blood in the glomerulus (cid:8869) affected by afferent and efferent arteriolar vasoconstriction r vasodilation. Vaso constrict afferent anethole less blood in glomerulus poc falls. Vaso dilate afferent anethole s more blood in. Vasoconstriction of efferent anethole d blood outflow from gc to c volume .
