Renal 4

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

ADH is not:
Released from the posterior pituitary
Released by decreased blood pressure
released after you feel thirst
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
Rennin: released by kidneys
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 total blood volume
increase total peripheral resistance
increase sodium and water reabsorption
increase K⁺ and H⁺secretion
Mark!

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

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

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

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