Chapter 24 Urinary System --Hormones & Enzymes

the adrenal cortical hormone that stimulates the distal tubule to reabsorb sodium and excrete potassium

Aldosterone

the mineralcorticoid tha ti scalled the salt-retaining hormone

Aldosterone

a deficiency of this hormone causes polyuria (diuresis) sometimes up to 25L a day; this hormone deficiency is called diabetes insipidus

ADH

secreted by the posterior pituitary gland, this hormone affects the permeability of the collecting duct to water

ADH

secreted by the atrial walls in response to an increase in blood volume; causes the excretion of sodium and water

ANP

a deficiency of this hormone causes the urinary excretion of Na and water and the retention of K

Aldosterone

ACE inhibitors block the formation of this vasopressor hormone

Angiotensin II

hormone that stimulates the adrenal cortex to secrete aldosterone and causes vasoconstriction of the peripheral blood vessels, thereby elevating blood pressure

Angiotensin II

hormone that is released in response to ventricular stretch; elevated in heart failure

BNP

a deficiency of this hormone causes hypocalcemic tetany

PTH

an excess of this hormone can cause hypercalcemia and kidney stones

PTH

stimulates the renal tubules to reabsorb calcium and to excrete phosphate

PTH

enzyme that changes Angiotensin 1 to Angiotensin II

converting enzyme

hormone that is deficient in a patient with chronic renal failure; causes anemia

erythropoietin

released by the kidney in response to hypoxemia; it stimulates red blood cell production by the bone marrow

erythropoietin

enzyme that activates angiotensinogen to angiotensin 1

renin

secreted by the juxtaglomerular apparatus (JGA) when blood pressure or blood volume decreases

renin
