Describe two mechanisms in the PCT, one in the nephron loop, one in the DCT, and one in the collecting duct for reabsorption of Na . What other solutes are reabsorbed or secreted with Na  in each mechanism?

Pressure in the renal artery is 100 mm Hg and the pressure in the renal vein is 50 mm Hg. The resistance of the afferent arteriole equals 0.5 mm Hg•min/L and the resistance of the efferent arteriole equals 0.5 mm Hg•min/L. What is the pressure in the glomerulus?

Identify the parts of the nephron where blood pH is regulated. Describe how blood pH is regulated – what ions are reabsorbed or secreted when pH is low or high

Make a diagram of Nephron Function diagram the changes that occur in osmolarity and volume of the filtrate as it moves through the nephron and collecting duct. Draw the diameter of the nephron proportional to the volume of the filtrate and the color intensity of the filtrate proportional to the osmolarity. Make sure to draw a gradient arrow for the osmolarity of the interstitial fluid.

The amount of a substance excreted from the kidneys is calculated by which of the following equations ? filtration 1 + secret - reabsorption filtration - secretion - reabsorption filtration - ( eretionre reabsorption )
