Renal 4

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

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

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

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

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

Which is not true of water regulation
The systems are independent of each other
Salt and water balancing systems always work together
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
All systems have equal response time
Baroreceptors - Chemoreceptors - Stress hormones - Capillary fluid shift - Renal
Baroreceptors - Chemoreceptors - Stress hormones - Renal - Capillary fluid shift
Mark!

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

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