As Diane completes her race, what enables -Diane's sports drink helped to replace sodium and water lost
her body to maintain homeostasis despite due to sweating.
her increased activity? -Diane's body produces more angiotensin II, allowing her
body to constrict blood vessels and increase her blood
pressure.
-Diane's kidney reabsorbs more water and sodium in response
to ADH and aldosterone.
Michael's pulmonary edema leads - His CO2 level is increased because his lungs have difficulty
to respiratory acidosis. removing it from the bloodstream.
How does pH impact Michael's basal -His K+ is elevated because, as H+ moves inside of cells in an
metabolic panel? attempt to get it out of the bloodstream, K+ moves from cells
into the bloodstream.
-His sodium level is decreased due to hypervolemia.
