1
Q

“effective osmoles”

A

sodium, glucose, mannitol, sorbitol.

Extracellular Na is the main determinant of plasma tonicity (ability of solutes to drive an osmotic driving force that causes water to move from one compartment to another)

2
Q

Effects of increased ECF tonicity (aka too much sodium)

A
  • increased thirst

- release of ADH

3
Q

SIADH (Syndrome of inappropriate ADH)

A

Clinical syndrome of nonosmotic release or enhancement of ADH action leading to pathologic water retention and hyponatremia

4
Q

Central Diabetes Insipidus

A

syndrome of ADH deficiency leading to excessive renal water loss

5
Q

Nephrogenic Diabetes Insipidus

A

certain disorder(s) that cause tubular unresponsiveness to ADH that creates a renal concentrating defect that leads to excessive renal losses of water
