Flashcards in Cardiac (lecture) Deck (10):
1

Short term BP regulation w/ elevated BP

Nervous system regulates via (antagonistic) sympathetic and (agonistic) parasympathetic responses

2

Short term BP regulation w/ decreased BP

Nervous system regulates via (agonistic) sympathetic and (antagonistic) parasympathetic responses

3

Long term BP regulation w/ elevated BP

Endocrine reponse

Lower RAAS

4

Long term BP regulation w/ decreased BP

Endocrine reponse

Increase RAAS

5

RAAS

Renin

Angiotensin I

Angiotensin II

Aldosterone

6

Renin

Made in kidneys

Activates Angiotenisn I

7

Angiotensin I

Made in blood stream

Activates Angiotensin II

8

Angiotensin II

Made in lungs

Activates aldosterone

9

Aldosterone

Made in adrenal cortex

Increases Na in blood; increased H20 via osmosis; increases plasma; increases blood pressure

10

Three factors impacting TPR

1) Vessel diameter (*arteries, arteriosclerosis)

2)Blood viscocity (*RBC ct, 

3) vessel length
