Correct Answer is C
Explanation
A. Stomach: Begins protein digestion (pepsin) but does not complete digestion of carbs and most lipids.
B. Colon: Primarily involved in water absorption and fecal formation, not extensive enzymatic digestion of macronutrients.
C. Duodenum: Receives bile and pancreatic enzymes; major site where carbohydrates, lipids, and proteins are enzymatically broken down into absorbable units.
D. Jejunum: Major site of nutrient absorption after digestion, but the initial/completion of enzymatic digestion occurs in the duodenum.
Correct Answer is D
Explanation
A. Blood pressure increases: Parasympathetic activity tends to reduce vascular tone and cardiac output, so blood pressure usually decreases rather than rises.
B. Bronchioles dilate: The parasympathetic system causes bronchoconstriction, while bronchodilation is a sympathetic response.
C. Pupils dilate: Pupil dilation (mydriasis) is controlled by the sympathetic system; the parasympathetic system produces constriction (miosis).
D. Heart rate decreases: Parasympathetic stimulation via the vagus nerve slows SA node firing, leading to a reduced heart rate.
