Hemorrhage

Question 0

ADH causes

Answer 0

water reabsorption at kidney & vasoconstriction

Increase in blood volume

Question 1

Anti-diuretic hormone secretion is determined by?

Answer 1

high- and low-pressure baroreceptors & osmoreceptors

Question 2

how does ADH secretion occur?

what is the mechanism resulting in ADH secretions

Answer 2

baroreceptors send signal to CV control center which sends axons to neurons in hypothalamus which makes ADH

Question 3

ADH =

Answer 3

anti-diuretic hormone

Question 4

What does the renin-angiotensis-aldosterone system do?

Answer 4

increase SVR, H2O, and salt retention at kidney

Question 5

Angiotensin II acts in brain to

Answer 5

stimulate release of ADH

Question 6

Angiotensin II acts in adrenal gland to..

Answer 6

make aldosterone which => NaCl reabsorption

Question 7

Angiotensin Converting Enzyme (ACE) converts

Answer 7

angiotensin I to angiotensin II

Question 8

Renin converts

Answer 8

angiotensinogen to Angiotensin I which goes to lunch where ACE converts it to Angiotensin II which goes to the adrenal gland which makes aldosterone which goes back to kidney

Question 9

GFR (glomerular filtration rate) is the

Answer 9

flow rate of filtered fluid thru kidney

Question 10

Where does GFR occur?

Answer 10

glomerular capillaries

Question 11

you ^ GFR to

Answer 11

eliminate excess fluid

Question 12

you decrease GFR to

Answer 12

preserve fluid

vasoconstriction @ afferent arteriole to ^P upstream & decrease P downstream

Question 13

Where does reabsorption of fluid/salt occur?

Answer 13

peritubular capillaries in series w/ glomerular capillaries

Question 14

you ^ reabsorption to

Answer 14

preserve fluid

Question 15

you decrease reabsorption to

Answer 15

eliminate fluid

Question 16

If low-pressure baroreceptors detect high blood volume,

Answer 16

they stimulate a decrease in renal sympathetic nerve activity => dilates vasculature => ^GFR => decreases renal reabsorption b/c of a decrease in ADH release => decreases in renin release => decrease in SVR

Question 17

If low-pressure baroreceptors detect low blood volume,

Answer 17

they stimulate an ^ in renal sympathetic nerve activity => constricts vasculature => decreases GFR => ^ renal reabsorption b/c of a ^ in ADH release => ^ renin release => ^ SVR
