• A. D-Unicellular glandular epithelium, goblet cells, secrete saliva
• B. B-Squamous epithelium, walls of blood vessels, form a diffusion boundary
• C. A-Cuboidal epithelium, ducts of glands, secretion and absorption
• D. C-Columnar epithelium, lining of stomach, secretion and absorption

Answer 1

The Correct Option is D

The given figure A is squamous epithelium, found in walls of blood vessels and air sacs of lungs and is involved in functions like forming a diffusion layer. B is cuboidal epithelium, found in ducts of glands and tubular parts of nephrons of kidney and its main functions are secretion and absorption. C is columnar epithelium, found in lining of stomach and intestine and helps in secretion and absorption. D is ciliated columnar epithelium, present in inner surface of hollow organs like bronchioles and Fallopian tubes and helps to move particles or mucus in a specific direction over the epithelium.
