1) From the list of treatment groups (substances or solutions) : Water, Soda, Caffeine free Soda, Cranberry juice, Gatorade, Water with baking soda, No Fear energy drink, Rockstar energy drink, Red Bull energy drink, TUMS antacids, Pretzels, Potato Chips etc.
a) What potential treatment groups could cause an increase in ADH secretion? Explain why.
b) What potential treatment groups could cause a decrease in aldosterone secretion? Why?
c) Predict the change/ effect in urine composition (pH, specific gravity, volume, color, and hormone levels (ADH, aldosterone))
2 What is the impact of blood pressure on kidney function?
3 Did your results illustrate the kidney's handling of water and salt loads? Explain.
4 What are potential sources of error in these experiments?
5 The loss of water during sweating on a hot day causes the blood volume to decrease and the osmolarity of body fluids to increase. Outline the mechanisms operating to restore homeostasis via the release of ADH in this situation. (a diagram / step by step / mechanism / map will be preferred )
6 Why would prolonged elevations of blood aldosterone produce hypertension?
7 Explain, physiologically, why a person urinates more after a night of beer consumption.
