Question

Quizplus · Accepted Answer

The renin-angiotensin-aldosterone pathway helps regulate blood pressure by increasing vasoconstriction and retaining salt and water. The lungs produce and release angiotensin-converting enzyme (ACE), a key enzyme in the pathway. ACE converts angiotensin I to angiotensin II, which is a potent vasoconstrictor and helps stimulate the release of aldosterone to retain salt and water. Therefore, the lungs play a crucial role in the regulation of blood pressure through this pathway. The lungs do not have a direct role in regulating blood pH or carbon dioxide levels.
