Scenario: 1. A drop in blood pressure causes the kidney to secrete renin 2. Renin causes the conversion of a plasma protein to angiotensin I. 3. Conversion of angiotensin I to angiotensin II is caused by an enzyme in the lungs 4. Angiotensin II causes an increase in aldosterone secretion from the adrenals
Based on the example below (and not really knowing anything about these pathways and chemicals what is the: 1)
What is the indirect cause of an increase in angiotensin 1 levels?
