Multiple Choice

Which of the following correctly matches the epithelial tissue type with its primary function?

Transitional epithelium – secretion of mucus

Verified step by step guidance

Step 1: Understand the primary functions of epithelial tissue types. Epithelial tissues are specialized for various functions such as protection, absorption, secretion, and filtration. Each type of epithelial tissue has a structure that aligns with its function.

Step 2: Analyze the function of transitional epithelium. Transitional epithelium is found in areas like the urinary bladder and is specialized for stretching and recoiling, not secretion of mucus. This eliminates the first option.

Step 3: Evaluate simple squamous epithelium. Simple squamous epithelium consists of a single layer of flat cells, which allows for efficient diffusion and filtration, such as in the alveoli of the lungs and the glomeruli of the kidneys. This matches the correct answer provided in the problem.

Step 4: Examine stratified cuboidal epithelium. Stratified cuboidal epithelium is typically found in glandular ducts and is involved in protection rather than absorption of nutrients. This eliminates the third option.

Step 5: Assess simple columnar epithelium. Simple columnar epithelium is found in areas like the digestive tract and is specialized for absorption and secretion, not protection against abrasion. This eliminates the fourth option.
