    1. …urinary sodium excretion returns to match levels of intake
    2. …plasma renin activity acts via negative feedback to decrease aldosterone concentration
    3. …aldosterone potency decreases due to overproduction
    4. …aldosterone activity is decreased by introducing drugs such as spironolactone
    5. …aldosterone receptors become over-saturated and are removed from the membrane
    1. Vasopressin

    1. ANP
    2. ADH
    3. Renin
    4. Angiotensin II
    5. Aldosterone
    1. It occurs with decreased filtration fraction
    2. It is due to inhibition of distal sodium reabsorption in the kidney
    3. It is a plausible explanation for the pitting edema in a patient with Conn’s syndrome
    4. It is associated with decreased renal plasma flow
    5. It is caused by decreased hydrostatic pressure in the peritubular capillary
