Angiotensin II is a protein that, in some people, leads to high blood pressure when it is present in high amounts. The pathway for production of this protein is shown below (Enzymes are in the boxes). Describe 3 ways the level of angiotensin II could be reduced in the body.

Solution

1.Angiotensin II receptor blockers block the movement of angiotensin II, allowing blood vessels to widen (dilate). Drugs such as angiotensin-converting enzyme inhibitors are also used.

2. Salt intake – increasing salt concentration decrease aldosterone. Decrease in renin happens if there\'s a increasein sodium and a increase in blood stress, that\'s sensed through the kidneys.
In addition, high blood can stimulate the sympathetic system and decrease renin , which decrease conversion of angiotensinogen to angiotensin I, and so the cylce continues. However, given that angiotensin I has to be converted to angiotensin II hormone by using the angiotensin-converter enzyme.

3. Potassium will increase aldosterone. For dietary potassium avoid avocados, dates, bananas, tempeh and vegetables. So by decreasing aldosterone, decrease angiotensin
