Renin, Angiotensin, Aldosterone

Question 1

• ADH triggers water resorption here
• Secretion of H +, creatinine and drugs

Answer 1

Collecting Ducts

Question 2

What is the trigger for the Renin, Angiotensin, Aldosterone system

Answer 2

Low BP
Low sodium

Question 3

What is the end result of the renin angiotensin aldosterone system is the release of aldosterone. What are the effects of aldosterone

Answer 3

Increased HR and vasoconstriction, which increase blood pressure
and reabsorbs water and sodium

Question 4

When there is low blood pressure or sodium, the kidneys release….

Answer 4

Renin (which is an enzyme)

Question 5

When there is low BP or sodium, the kidneys release Renin (enzyme) which then acts on….

Answer 5

Angiotensinogen

Question 6

When there is low blood pressure or sodium, the kidneys release renin (enzyme). Renin acts on angiotensinogen, which converts it to….

Answer 6

Angiotensin 1

Question 7

When there is low BP or sodium, the kidneys release renin (enzyme). Renin acts on angiotensinogen which then converts it to angiotensin 1. Angiotensin 1 then travels to the _____________ where ACE converts it to…..

Answer 7

Lungs
Angiotensin 2

Question 8

When there is low BP or sodium, the kidneys release renin (enzyme). Renin acts on angiotensinogen, which then converts it to angiotensin 1. Angiotensin 1 then travels to the lungs where ACE converts it to angiotensin 2. Angiotensin 2 then travels to the _____________ and triggers the release of…..

Answer 8

Adrenals
Aldosterone

Question 9

When there is low BP or sodium, the kidneys release renin (enzyme). Renin acts on angiotensinogen, which then converts it to angiotensin 1. Angiotensin 1 then travels to the lungs, where ACE converts it to angiotensin 2. Angiotensin 2 then travels to the adrenals and triggers the release of aldosterone. Aldosterone then causes….

Answer 9

Increased HR and vasoconstriction to increase BP
and reabsorption of water and sodium

Question 10

Azotemia

Answer 10

Increased BUN and or creatinine
