E)All of the answers are correct.

Question

Quizplus · Accepted Answer

The converting enzyme secreted by the alveolar capillaries is angiotensin-converting enzyme (ACE), which plays a role in the hormonal regulation of blood volume and pressure by converting angiotensin I to angiotensin II. Angiotensin II is a potent vasoconstrictor and can increase blood pressure by increasing peripheral resistance and causing the release of aldosterone, which promotes salt and water retention.

Therefore, choice B is the correct answer as the converting enzyme secreted by the alveolar capillaries plays a role in the hormonal regulation of blood volume and pressure. The other options are not functions of this enzyme.
