Concept:
Different parts of the nephron are lined with specific types of epithelium suited to their function.
• Bowman's capsule (parietal layer): Simple squamous epithelium (thin for filtration)
• Proximal convoluted tubule (PCT): Simple cuboidal epithelium with brush border
Step 1: Understand analogy.
The analogy compares structure with type of epithelium.
Step 2: Identify PCT lining.
PCT is lined by simple cuboidal epithelium with microvilli for absorption.
Step 3: Understand function.
• Squamous epithelium: Thin for filtration
• Cuboidal epithelium: Thick with microvilli for reabsorption
Step 4: Analyze options.
• (A) Ciliated: Found in respiratory tract
• (B) Cuboidal: Correct
• (C) Squamous: Already given for Bowman's capsule
• (D) Transitional: Found in urinary bladder
Step 5: Conclusion.
Thus, PCT is lined with cuboidal epithelium.
Final Answer: Option (B)
