Based on their function, where would you expect to find microvilli to be in the body?
Fallopian tubes
Digestive tract
Urinary tract
Respiratory tract
The Correct Answer is B
A. Fallopian tubes: The Fallopian tubes have cilia, not microvilli. Cilia help move the egg toward the uterus.
B. Digestive tract: Microvilli are found on the epithelial cells of the small intestine. They increase the surface area for maximum nutrient absorption.
C. Urinary tract: While some absorptive and secretory functions occur in the nephron, microvilli are not prominent structures throughout the urinary tract.
D. Respiratory tract: The respiratory tract is lined with ciliated epithelium, which helps move mucus, not with microvilli for absorption.
