Which of these chemical substances, when released into the blood, would cause blood pressure to decrease?Multiple ChoiceAldosteroneAtrial natriuretic factorAngiotensinVasopressinEpinephrine
Solution
The chemical substance that, when released into the blood, would cause blood pressure to decrease is the Atrial natriuretic factor. This hormone is produced by the heart's atria and it helps to reduce blood pressure by decreasing blood volume. It does this by promoting the excretion of sodium and water by the kidneys, which in turn decreases the volume of blood, and thus, the blood pressure.
