The cortical nephron is characterized by all of the following except:
a.
short nephron loop
b.
glomerulus is further from the cortex-medulla junction
c.
glomerulus is close to the cortex-medulla junction
d.
efferent arteriole supplies peritubular capillaries
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.
What condition could cause the bloodstream to be hypertonic relative to the nephron?

Extremely rapid weight loss may cause this tissue to shrink so that the kidneys slip from their normal position. On rare occasions, the slippage can put a kink in one or both ureters and block urine flow. Suggest what might then happen to the kidneys.arrow_forward
