Random Length: 110 Questions
Section 1: Reading (Questions 1–18)
Passage 1 (Questions 1–5): The renin-angiotensin-aldosterone system (RAAS) is a hormone system that regulates blood pressure and fluid balance. When blood pressure drops, the kidneys release renin. Renin converts angiotensinogen to angiotensin I, which is then converted to angiotensin II by angiotensin-converting enzyme (ACE). Angiotensin II causes vasoconstriction and stimulates aldosterone release, leading to sodium and water retention, which increases blood pressure.
