The Correct Answer is {"dropdown-group-1":"B"}
A. Cephalic: The cephalic phase occurs before food enters the stomach, triggered by sight, smell, or thought of food, and stimulates gastric secretion via the vagus nerve.
B. Gastric: The gastric phase begins when food enters and stretches the stomach, triggering myenteric and vagovagal reflexes that stimulate acid and enzyme secretion.
C. Intestinal: The intestinal phase involves chyme entering the duodenum, which moderates gastric activity, mostly inhibitory.
D. Gastrointestinal: “Gastrointestinal” is a general term and not one of the specific phases of gastric secretion.
E. Mesenteric: “Mesenteric” refers to the mesentery (tissue supporting the intestines), not a phase of digestion.

Correct Answer is C
Explanation
A. Glomerular filtration rate will increase: Vasoconstriction of the efferent arteriole increases resistance, raising glomerular pressure and increasing GFR.
B. Urine output will increase: Increased GFR results in more filtrate, which can lead to increased urine output.
C. Systemic blood pressure will go up: This is unlikely to be directly caused by local vasoconstriction of the efferent arteriole. Systemic BP is mainly influenced by overall vascular resistance and cardiac output.
D. Net filtration pressure will increase: Efferent arteriole constriction backs up pressure in the glomerulus, increasing net filtration pressure.
Correct Answer is {"dropdown-group-1":"A","dropdown-group-2":"A"}
Explanation
A. Keratinized; lingual papillae: The dorsal surface of the tongue is lined with keratinized stratified squamous epithelium, especially in areas subject to friction, and contains lingual papillae that house taste buds.
B. Keratinized; lingual frenulum: The lingual frenulum is the fold under the tongue, not a bump or papilla.
C. Nonkeratinized; lingual papillae: The top of the tongue is typically keratinized, not nonkeratinized, due to exposure to friction.
D. Nonkeratinized; tonsils: Tonsils are not part of the tongue's surface epithelium and don’t contain taste buds.
E. Nonkeratinized; vallate papillae: Vallate papillae are a type of lingual papillae, but the overall surface is keratinized, not nonkeratinized.
