Question

1. which type of epithelial tissue is specialized for absorption?

○ simple cuboidal epithelium
○ simple columnar epithelium
○ transitional epithelium
○ stratified squamous epithelium

Explanation:

To determine the epithelial tissue specialized for absorption, we analyze each option:

• Simple cuboidal epithelium: Involved in secretion and absorption (e.g., in kidney tubules and glands), but simple columnar is more associated with absorption in areas like the small intestine.
• Simple columnar epithelium: Lines the digestive tract (e.g., small intestine) and is highly specialized for absorption, with microvilli to increase surface area for nutrient uptake.
• Transitional epithelium: Adapts to stretching (e.g., in the urinary bladder), not for absorption.
• Stratified squamous epithelium: Provides protection (e.g., in skin, mouth), not absorption.

Among these, simple columnar epithelium is the primary type specialized for absorption.

Answer:

B. Simple columnar epithelium (Note: Assuming the second option with the arrow is labeled as B for clarity; the correct option is "Simple columnar epithelium")
