Renal 4

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

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

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

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

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

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

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

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

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