1
Q

Where is Renin produced?

A

The Juxtaglomerular apparatus of the kidneys

2
Q

Where is Angiotensinogen produced?

A

The liver

3
Q

When is Renin produced?

A

When there is decreased plasma volume (low BP)

4
Q

What does Renin do?

A

It converts Angiotensinogen into Angiotensin I

5
Q

Where is Angiotensin Converting Enzyme (ACE) produced?

A

In pulmonary endothelium

6
Q

What does ACE do?

A

It converts Angiotensin I into Angiotensin II

7
Q

What are the effects of Angiotensin II on the body?

A
  • Vasoconstriction
  • ADH release
  • Thirst stimulation
  • Stimulates the release of aldosterone from the adrenal cortex
8
Q

Where is Aldosterone produced?

A

Zona glomerulosa in the adrenal cortex

9
Q

What does Aldosterone do?

A

Increases Na+ and water reabsorption in the kidneys

10
Q

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

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