1

Where is Renin produced?

The Juxtaglomerular apparatus of the kidneys

2

Where is Angiotensinogen produced?

The liver

3

When is Renin produced?

When there is decreased plasma volume (low BP)

4

What does Renin do?

It converts Angiotensinogen into Angiotensin I

5

Where is Angiotensin Converting Enzyme (ACE) produced?

In pulmonary endothelium

6

What does ACE do?

It converts Angiotensin I into Angiotensin II

7

What are the effects of Angiotensin II on the body?

- Vasoconstriction
- ADH release
- Thirst stimulation
- Stimulates the release of aldosterone from the adrenal cortex

8

Where is Aldosterone produced?

Zona glomerulosa in the adrenal cortex

9

What does Aldosterone do?

Increases Na+ and water reabsorption in the kidneys

10

What leads to an increased plasma volume (increase in BP)?

- Vasoconstriction
- ADH release
- Thirst stimulation
- Increased Na+ and water reabsorption in the kidneys
