Question details

1. The drawing shown below represents part of the arrangement of blood vessels in the kidney. The arrangement includes 2 sets of resistance vessels (afferent and efferent arterioles (afferent artery and efferent artery) separated by a capillary bed, the glomerulus (glom). Note that the kidney glomerulus is an example of a fenestrated capillary, so fluid is filtered from the capillary (into Bowmans space) when the resistance of the efferent artery (downstream, to the right) is higher than the afferent (upstream, to the left). Use the diagram and values provided to answer parts a, b, c and d. renal art 63 mm H Prealven mm Hg Poom 0.012 mmHg min/ml Rem 0.003 mmHg min/ml Pint -G (Toap Tint o 1 for kidney capilaries; disregard K for the following calculations.

Is there net filtration (fluid loss) or reabsorption (fluid uptake into the capillary) in this capillary bed? c) If the efferent arteriole is dilated, such that Renan 0.001, what is the new value for Poom? d) With Remi 0.001, calculate the new flux (J) through the glomerular capillary bed. Is there net filtration or reabsorption in this capillary bed?
