Quiz 10 Flashcards
Aldosterone
stimulates sodium reabsorption in kidney principal cells.
The hormone that directly controls water reabsorption by the kidneys is
vasopressin (ADH)
Angiotensin II stimulates
thirst, vasoconstriction, and synthesis and release of aldosterone
The ________ cells of the distal nephron contribute to acid-base regulation
intercalated
When baroreceptors in the carotid and aortic bodies register increased blood pressure, this results in
inhibition of vasopressin secretion
Juxtaglomerular cells, also known as Granular cells secrete
renin
When venous return is increased, stretch receptors in the atria of the heart are activated. This results in
decreased vasopressin (ADH) secretion.
The primary osmoreceptors are located in the
hypothalamus
Why is sodium actively reabsorbed in the nephron?
to increase passive reabsorption of water
Atrial natriuretic peptide
increases GFR and inhibits release of renin
The two organ systems that work together to regulate most aspects of the body’s water balance are
urinary and cardiovascular.
