Renal 4

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

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

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

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

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

Which is not true of water regulation
ADH - maintains water balance
The systems are independent of each other
Renin-Angiotensin-Aldosterone regulates salt 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 - Renal - Capillary fluid shift
All systems have equal response time
Baroreceptors - Chemoreceptors - Stress hormones - Capillary fluid shift - Renal
Stress hormones - Baroreceptors - Chemoreceptors - Capillary fluid shift - Renal
Mark!

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

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