QUESTION 11
Place the following steps in the renin-angiotensin-aldosterone system (RAAS) that occur
when blood volume and blood pressure drop.
renin speeds up conversion of angiotensinogen to angiotensin I (AGI)
juxtaglomerular cells release the enzyme renin into the blood
angiotensin-converting enzyme (ACE) speeds up conversion of angiotensin I to
the hormone angiotensin I
drop in blood pressure and blood volume are detected by juxtaglomerular cells
in the kidneys
a) aldosterone increases reabsorption of Na+ ions into blood; water follows by
osmosis which increases blood volume which in turn increases blood pressure
b) ADH stimulates increased water reabsorption by the kidneys which I
increases blood volume and so increases blood pressure
c) person drinks water which increases blood volume and so increases blood
pressure
simultaneously angiotensin II then
a) increases blood pressure by vasoconstricting the blood vessels
b) stimulates the adrenal cortex to secrete aldosterone
c) stimulates the posterior pituitary gland to release antidiuretic hormone (ADH)
d) stimulates the thirst centers in the hypothalamus

Expert Solution
Step 1

Blood pressure is the pressure that can be felt against arterial walls that are caused by the circulating blood in them. It can be measured using a sphygmomanometer.
