Activation of the renin-angiotensin-aldosterone system:
Causes albuminuria
Reabsorbs K⁺ and eliminates Na⁺ in the urine
Expands blood volume, increasing blood pressure
Causes hematuria
The Correct Answer is C
A. Causes albuminuria: Albuminuria (protein in urine) is a sign of kidney damage, not a direct effect of RAAS activation.
B. Reabsorbs K⁺ and eliminates Na⁺ in the urine: RAAS does the opposite-it reabsorbs sodium and excretes potassium.
C. Expands blood volume, increasing blood pressure: RAAS activation leads to vasoconstriction and sodium/water retention, which raises blood pressure.
D. Causes hematuria: Hematuria (blood in urine) is typically a sign of trauma, infection, or kidney disease-not directly linked to RAAS.

Correct Answer is A
Explanation
A. Stomach: The esophagus carries food from the pharynx and empties it into the stomach via the lower esophageal sphincter.
B. Cecum: The cecum is part of the large intestine and is much further along in the digestive tract.
C. Common bile duct: This duct transports bile, not food. It is not directly connected to the esophagus.
D. Duodenum: The duodenum is the first part of the small intestine, which comes after the stomach, not directly after the esophagus.
Correct Answer is D
Explanation
A. Causes Na⁺ excretion: Aldosterone promotes sodium reabsorption, not excretion, to increase blood volume and pressure.
B. Depletes blood volume: Aldosterone increases blood volume by retaining sodium and water.
C. Causes K⁺ reabsorption: Aldosterone promotes potassium excretion, not reabsorption.
D. Causes Na⁺ and water reabsorption: Aldosterone acts on the renal tubules to reabsorb sodium, which draws water back into circulation, increasing blood volume.
