⩥ Metabolic alkalosis can cause what?
Answer: Hypoglycemia


⩥ Osmolality
Answer: Measure of a solute concentration in a solution. Higher number
of solutes in a compartment = higher concentration and less water


⩥ Osmosis
Answer: Movement of water from low concentration to high
concentration


⩥ Osmotic pressure
Answer: Amount of pressure or force that is exerted by solute molecules
of a given compartment. PULLS water into a higher concentration.
HIGHER osmolality = HIGHER osmotic pressure


⩥ Hydrostatic pressure
Answer: Force within a fluid compartment. PUSHES fluid outside of
compartment (OPPOSES OSMOSIS).

, Ex. blood pressure


⩥ Oncotic pressure
Answer: Force that KEEPS water/fluid within a compartment. PULLS.


⩥ Antidiuretic hormone
Answer: VASOPRESSIN. Secreted by pituitary gland in response to
water deficit, sodium excess, or low BP. Causes kidneys to reabsorb
water thus increasing intervascular/plasma fluid.


⩥ Renin Angiotensin Aldosterone System (RAAS)
Answer: Activated by low blood volume. Low blood volume --> renin --
> angiotensinogen --> angiotensin 1 --> ACE (angiotensin converting
enzyme) converts angiotensin 1 to angiotensin 2 -->causes arterial
vasoconstriction --> release of aldosterone --> renal Na+ and H2O
reabsorption and K+ excretion.


Produces LESS urine and blood volume INCREASES.
Manages BP - when body constricts, BP increases


⩥ Normal plasma osmolality
Answer: 280-295 mOsm/kg


⩥ Natriuretic hormones
