Renal 4

Osmoreceptors do not:
release more action potentials when the cell is dehydrated
release more action potentials when water concentration is high
Allow Na to enter in hypertonic solutions
have stretch inhibited cation channels
Mark!

ADH is not:
Released by decreased blood pressure
a hormone that causes vesicles to surface in the collecting duct
released after you feel thirst
Released from the posterior pituitary
Mark!

Select the false hormone: effect relationship:
Rennin: released by kidneys
Aldosterone: more Na⁺ absorption
Angiotensin I: inactive precursor
Angiotensin II: produced in lungs
Mark!

Angiotensin II does not
increase Na⁺ and water reabsorption in proximal and distal tubules
rely on renin and ACE for its production
decrease total peripheral resistance
increase aldosterone levels
Mark!

Aldosterone does not
Increase total blood volume
increase total peripheral resistance
increase K⁺ and H⁺secretion
increase sodium and water reabsorption
Mark!

Which is not true of water regulation
Salt and water balancing systems always work together
The systems are independent of each other
Renin-Angiotensin-Aldosterone regulates salt balance
ADH - maintains water balance
Mark!

Which is the correct order of system actuation to maintain homeostasis
Stress hormones - Baroreceptors - Chemoreceptors - Capillary fluid shift - Renal
Baroreceptors - Chemoreceptors - Stress hormones - Renal - Capillary fluid shift
All systems have equal response time
Baroreceptors - Chemoreceptors - Stress hormones - Capillary fluid shift - Renal
Mark!

Atrial Natriuretic Peptide does not target which organ:
Hypothalamus
Adrenal glands
Heart
Kidneys
Mark!

Which hormone causes water loss:
ADH
Aldosterone
ANP
Angiotensin II
Mark!
