Which of the following is true about the structures of the digestive tract?
The stomach wall is thrown into folds called villi and microvilli
The esophagus connects the pharynx with the trachea
The pyloric sphincter and ileocecal valve are located at the entrance and exit of the small intestine
The cecum and colon are parts of the small intestine
The Correct Answer is C
A. The stomach wall is thrown into folds called villi and microvilli: Villi and microvilli are found in the small intestine, not the stomach. The stomach has rugae.
B. The esophagus connects the pharynx with the trachea: The esophagus connects the pharynx to the stomach; the trachea connects to the lungs.
C. The pyloric sphincter and ileocecal valve are located at the entrance and exit of the small intestine: The pyloric sphincter regulates entry from the stomach to duodenum, and the ileocecal valve controls flow from the ileum to cecum.
D. The cecum and colon are parts of the small intestine: They are parts of the large intestine, not the small intestine.

Correct Answer is B
Explanation
A. pH 5.0: This is within normal range (urine pH typically ranges from 4.5 to 8.0).
B. Large amount of white blood cells (WBC): A high WBC count in urine indicates possible infection or inflammation, such as a urinary tract infection (UTI), and should be reported.
C. Amber color: Normal urine is straw to amber in color, depending on hydration status. This is not abnormal.
D. Occasional casts: Occasional hyaline casts may be seen in healthy individuals, especially after exercise. Persistent or abnormal casts (e.g., RBC casts) would be more concerning.
