1 - renin
2 - Angiotensin II
3 - aldosterone
4 - antidiuretic hormone (ADH)
Followings are the important hormones/enzymes in renin-angiotensin-aldosterone
system. Choose an appropriate function for each hormone/enzyme.
aldosterone
Angiotensin II
renin
antidiuretic hormone (ADH)
1. Converts angiotensinogen to angiotensin I.
2. (1) Stimulates hypothalamus to triggers thirst and ADH secretion from pituitary.
(2) Constricts blood vessels.
(3) Stimulates adrenal cortex to trigger aldosterone secretion.
3. Increases Na+ retention while increases K+ excretion.
4. Increases renal water reabsorption.
,- Sympathetic nerve is stimulated.
- Renal perfusion pressure is decreased.
- [Na+] is low.
This figure is showing the entire flow of Renin-Angiotensin-aldosterone system from the
activation to the response of human body. Three blanks marked as "i" are the conditions
sensed by kidneys that will activate the system. Choose all the conditions, which will
activate this system.
- Parasympathetic nerve is stimulated.
- Renal perfusion pressure is increased.
- Sympathetic nerve is stimulated.
- [Na+] is high.
- Renal perfusion pressure is decreased.
- [Na+] is low.
beta natriuretic peptide (BNP)
- Water intake ↓
- urine Na+ ↑
- Suppression of renin-angiotensin-aldosterone system
- Inhibit secretion of ADH
- Na+ excretion ↑
- Inhibit salt appetite
- Relaxes blood vessel by suppressing sympathetic nervous system activity
,renin-angiotensin-aldosterone system
- vasoconstriction
- Na+ retension ↑
- water retention ↑
- secretion of ADH ↑
- K+ excretion ↑
- thirst
- Aldosterone level ↑
These physiological actions (or observation) are related to either beta natriuretic peptide
(BNP) or renin-angiotensin-aldosterone system.
Chose 1 for BNP: chose 2 for renin-angiotensin-aldosterone system.

1. beta natriuretic peptide (BNP)
2. renin-angiotensin-aldosterone system
- hypovolemia
- angiotensin II
- extracellular osmolarity ↑
Which of these is/are the stimulation leading to ADH release?
- hypovolemia
- extracellular osmolarity ↓
- aldosterone
- angiotensin II
- hypervolemia
- extracellular osmolarity ↑
plasma osmolality ↓
The syndrome of inappropriate antidiuretic hormone secretion (SIADH) is the condition
caused by excessive secretion of ADH from the posterior pituitary.
Which of the following do you expect to see in a patient with this condition?
- plasma osmolality ↓
