Problem
I. Extreme starvation can lead to a loss of fat from the adipose capsule of the kidney. This leads to drooping of the affected kidney, a condition called nephroptosis. Explain why a loss of the adipose capsule can lead to nephroptosis.
II. Ana has advanced kidney disease. As part of her routine lab work, her physician monitors her complete blood count to check the number of erythrocytes in her blood. The most recent test demonstrated that Ana had a much lower erythrocyte count than normal, leading her physician to diagnose her with anemia. What is the relationship between Ana's kidney disease and her anemia?
III. Your lab partner wonders how the cells of the renal tubules and ducts of the collecting system obtain oxygen and nutrients when their capillary bed is located only in the renal corpuscle. What is your lab partner misunderstanding about the blood flow in the kidney? Explain his mistake to him.
