Question

Choose the correctly matched pair.
A. Inner lining of salivary duct – ciliated epithelium
B. Moist surface of buccal cavity – glandular epithelium
C. Tubular parts of nephrons – cuboidal epithelium
D. Pancreatic duct – squamous epithelium

Answer 1

Hint: All the different types of epithelium helps the associated gland, surface, organ in enhancing their functionality and productivity. Match the function of organs and the character of epithelium together to get the correct answer.

Complete answer:
Epithelium is generally the surface lining present on the inside of any organ or gland. It helps in secretion, absorption and in many other ways so as to increase the working capacity of that specific organ or gland.
Now let us talk step by step, we know that the function of salivary duct is to secrete saliva and help in the first digestion of the food but the epithelium provided in the option is ciliated and these type of epithelium surfaces help in the absorption of the digested food and it is normally present in the inner lining of the small intestine.
Next on the list we have is the moist surface of the buccal cavity, we know that whatever food we eat that is needed to be moist so as to properly digest it and buccal cavity helps in keeping the food wet. But the epithelium present in it should be permeable and it should not let saliva diffuse through it and only squamous epithelium is known to be permeable therefore glandular epithelium is the wrong option. It is more of what present inside the glands.
Before we talk about cuboidal epithelium, we will first talk about the pancreatic duct and the function of pancreas is to secrete pancreatic juices to help in digestion. The epithelium which is helpful in secreting compounds is the simple cuboidal epithelium therefore our option D is also wrong.
Now finally we talk about the nephrons, they are the part of kidney and help in the absorption of all the essential compounds from the blood and therefore cuboidal epithelium helps in the absorption also as it has microvilli on the surface of its cell to increase absorptive area.

Therefore, the correct answer is option C.

Note:
The cuboidal epithelium is found at the places where the body needs to increase its absorptive area and also increase the rate of release of the compounds. So, this epithelium can be found at all places where the absorption and release occur. Like inner lining of bronchioles also have ciliated epithelium to increase absorption of oxygen into the blood.
