RAAS

Question 1

What does RAAS stand for?

Answer 1

Renin - Angiotensin - Aldosterone - System

Question 2

What does RAAS control?

Answer 2

Blood pressure

Question 3

What does the kidney emit?

Answer 3

Renin

Question 4

What are juxtaglomerular cells? What do they produce?

Answer 4

Prorenin; upon a drop in BP it is cleaved to form renin which is released into the blood

Question 5

What does renin convert to?

Answer 5

A plasma protein called angiotensinogen, into angiotensin 1

Question 6

What hormone does the liver produce?

Answer 6

Agiotensinogen

Question 7

What coverts angiotensin 1 into angiotensin 2?

Answer 7

Angiotensin converting enzyme (ACE)

Question 8

Where is the angiotensin converting enzyme located?

Answer 8

Lungs

Question 9

What effects does angiotensin 2 have?

Answer 9

Systematic vasoconstriction, promotes sodium reabsorption, induces the release of aldosterone from the adrenal cortex, induces the posterior pituitary to release antidiuretic hormone

Question 10

Atrial natriuretic peptide

Answer 10

Rise in BP results in stretch of the atria of the heart, triggering baroreceptors

Question 11

What does atrial natriuretic peptide inhibit?

Answer 11

Juxtaglomerular apparatus in the kidney from releasing renin

Question 12

What does renin cause

Answer 12

Vasoconstriction
