Impaired hepatic function:
Causes a deficiency of intrinsic factor and pernicious anemia
Causes lactose intolerance
Causes gastric reflux
Causes blood drug levels to reach toxic levels
The Correct Answer is D
A. Causes a deficiency of intrinsic factor and pernicious anemia: Intrinsic factor is produced in the stomach, not the liver. Its deficiency leads to pernicious anemia.
B. Causes lactose intolerance: Lactose intolerance is due to lactase deficiency in the small intestine.
C. Causes gastric reflux: Gastroesophageal reflux is typically due to lower esophageal sphincter dysfunction.
D. Causes blood drug levels to reach toxic levels: The liver metabolizes drugs. Impaired hepatic function reduces drug clearance, leading to accumulation and potential toxicity.

Explanation
A. Regulate blood volume: Kidneys regulate fluid balance by adjusting urine output, influencing blood volume.
B. Excrete solid waste: Kidneys excrete liquid waste (urea, creatinine), not solid waste; the GI tract handles solids.
C. Role in regulation of blood pressure: Via the renin-angiotensin-aldosterone system (RAAS), kidneys influence vascular resistance and fluid volume.
D. Regulate body temperature: Thermoregulation is managed by the hypothalamus and skin, not the kidneys.
E. Regulate electrolyte content of blood: Kidneys regulate levels of sodium, potassium, calcium, and phosphate in the blood.
F. Role in RBC production: By releasing erythropoietin, kidneys stimulate RBC production in the bone marrow.
Correct Answer is A
Explanation
A. Stomach: The stomach regulates the release of chyme into the duodenum via the pyloric sphincter, controlling the rate of gastric emptying.
B. Liver: The liver produces bile, but does not handle chyme or food bolus movement.
C. Colon: The colon processes waste after absorption and doesn’t interact with chyme from the stomach.
D. Esophagus: The esophagus moves food from the mouth to the stomach but does not regulate chyme delivery to the small intestine.
