2. Describe the various ways water is lost by the body
3. Describe the mechanisms for water gain
4. Explain the role of ADH in water conservation
5. Describe the stimuli for ADH release
6. Describe the mechanism of action for ADH to increase water reabsorption
7. Explain the counter-current system and how it sets up osmolar gradients in the kidney
8. Describe the renin-angiotensin-aldosterone system
9. Explain the role of aldosterone in sodium and/or potassium balance
10. Describe the stimuli for renin release
11. Describe the synthesis/release of aldosterone
12. Explain the effects of angiotensin II on blood pressure
13. Describe the effects of atrial natriuretic peptide on sodium and water balance
14. Describe the relationship between regulating blood volume and blood pressure
15. Explain the necessity to maintain normal electrolyte balance
16. Describe the effects of severe dehydration on the body
17. Explain the redundancy in the control of fluids and electrolytes
Acid-Base Balance
1. Define pH. Define neutral, acidic, and basic (alkaline) solutions.
2. What is the normal pH of blood?
3. Define acidosis and alkalosis. Compare metabolic and respiratory components of each.
4. Describe the various sources of acids and bases
5. Describe the buffers as a first line of defense against acid-base disturbances
6. How does the respiratory system compensate for a metabolic disturbance in acid-base balance?
7. How does the body compensate for a respiratory disturbance in acid-base balance?
8. Describe the renal handling of H+ and HCO3-
