Renal 4

Osmoreceptors do not:
have stretch inhibited cation channels
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
Mark!

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

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

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

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

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

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

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

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