BIOC34H3 Chapter Notes -Extracellular Fluid, Oncotic Pressure, Renal Function
Document Summary
Lastly, the expeiment helped us understand the specific affects of hormones such as anti diuretic hormone (adh) and aldosterone have on solute reabsorption and water uptake. In order to determine the effect of arteriole diameter on glomerular filtration the affeent radius was set to 0. 5 mm and efferent arteriole radius was set to 0. 45 mm. If the left beaker was not full the refill button was clicked. Pressure gauge was adjuste to 90 mm hg. Experiment was started and when the drain beaker was full the data was recorded (baseline). Next, the afferent radius was increased by 0. 05 mm and the steps were repeated. The activity was repeated until a max afferent adius of 0. 60 mm was reached. The afferent ateriole radius was the reduced to 0. 30 mm and exp. run. Effect of pressure on glomerular filtration was observed by highlighting pressure . It was mae sure the source beaker was filled with blood by clicking refill.
