Question: What is the primary effect of the renin-angiotensin-aldosterone system (RAAS)?

Options:

Correct Answer: Increase blood volume and pressure

Solution:

The RAAS primarily increases blood volume and pressure through the retention of sodium and water.

What is the primary effect of the renin-angiotensin-aldosterone system (RAAS)?

What is the primary effect of the renin-angiotensin-aldosterone system (RAAS)?

Step 1: The body detects low blood pressure or low blood volume.
Step 2: The kidneys release an enzyme called renin.
Step 3: Renin converts a protein in the blood called angiotensinogen into angiotensin I.
Step 4: Angiotensin I is converted into angiotensin II by an enzyme in the lungs.
Step 5: Angiotensin II has several effects: it constricts blood vessels to increase blood pressure.
Step 6: Angiotensin II stimulates the adrenal glands to release aldosterone.
Step 7: Aldosterone causes the kidneys to retain sodium and water.
Step 8: Retaining sodium and water increases blood volume, which raises blood pressure.
