Renal 4

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

ADH is not:
Released from the posterior pituitary
released after you feel thirst
a hormone that causes vesicles to surface in the collecting duct
Released by decreased blood pressure
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
increase aldosterone levels
decrease total peripheral resistance
rely on renin and ACE for its production
Mark!

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

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

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

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

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