Identify "D," one of the primary methods the body uses to increase blood pressure.
Increased water reabsorption in the collecting ducts of the kidneys
Estrogens are chemically similar to ____________ and enhance NaCl reabsorption by the renal tubules.
aldosterone
In Addison's disease, the adrenal cortex produces too little aldosterone, and so Na+ is lost. People with this disorder often crave ________.
salty foods
Match the electrolyte balance term with its correct characteristic: Hyponatremia.
A condition that results from solute loss, water retention, or both

Identify "A," one of the primary methods the body senses a decrease in blood pressure.
Decreased stretch in afferent arterioles
Identify the possible causes of hypernatremia at "A."
Dehydration; uncommon in healthy individuals; may occur in infants or the confused aged (individuals unable to indicate thirst) or may result from excessive intravenous NaCl administration
