Q. Regarding extracellular volume maintenance: (Solved)
1. control of sodium balance is the major mechanism maintaining ECF volume
2. a rise in ECF volume stimulates vasopressin secretion
3. osmotic stimuli over-ride volume stimuli in the regulation of vasopressin secretion
4. vasopressin causes Na+ retention by the kidney
5. angiotensin II inhibits aldosterone secretion
- a. control of sodium balance is the major mechanism maintaining ECF volume
