Multiple Choice

Which type of epithelial tissue is correctly matched with its typical location in the body?

Simple columnar epithelium – epidermis of the skin

Stratified cuboidal epithelium – alveoli of the lungs

Transitional epithelium – lining of the small intestine

Simple squamous epithelium – lining of blood vessels

Verified step by step guidance

Step 1: Understand the characteristics of epithelial tissue types. Epithelial tissues are classified based on the number of layers (simple or stratified) and the shape of the cells (squamous, cuboidal, columnar, or transitional). Each type has specific functions and locations in the body.

Step 2: Analyze the options provided. For example, simple columnar epithelium is typically found in areas like the digestive tract (e.g., lining of the stomach and intestines), not the epidermis of the skin. Stratified cuboidal epithelium is found in ducts of sweat glands, not in the alveoli of the lungs. Transitional epithelium is specialized for stretching and is found in the urinary bladder, not the small intestine.

Step 3: Focus on the correct answer. Simple squamous epithelium is a single layer of flat cells that allows for efficient diffusion and filtration. It is commonly found lining blood vessels (endothelium), alveoli of the lungs, and serous membranes.

Step 4: Relate the structure to the function. Simple squamous epithelium's thin, flat structure facilitates processes like gas exchange in the lungs and nutrient/waste exchange in blood vessels.

Step 5: Confirm the match between tissue type and location. The correct answer, 'Simple squamous epithelium – lining of blood vessels,' is consistent with the anatomical and physiological role of this tissue type.
