Describe in detail the physiology of aldosterone with respect to potassium balance (just K+, sodium is covered in the next question). Include a detailed description of what aldosterone is, where it comes from, and how its sectretion is regulated. Then describe its physiological effects (just with respect to K+) and explain why they are important.

Mary went to the doctor complaining of stomach cramps. After the doctor examined her he determined that she has peritonitis (inflammation of the peritoneum). He asked if she has had a UTI recently and she said yes. Why would a UTI in females lead to peritonitis but not in males? Fully detail the differences and possible pathogen pathway.

The loop of Henle is considered an engineering marvel. If the loop were straight, what negative effect would it have on the normal functioning of the kidney? Give your answer with particular relevance to the different permeabilities for water and salt in the various regions of the nephron and how the countercurrent multiplier and countercurrent exchange systems help maintain the osmotic gradient across the cortical medullary axis of the kidneys.
