Question

Lining of kidney tubules is made up of __________.

Answer 1

Hint: The kidney tubules are also known as renal tubules and it is that part of the nephron where the filtrate collects after filtering out from the glomerulus and it contains PCT, DCT, and Henle's loop.

Complete answer:
Epithelial tissue is the protective tissue which forms the border of different organs. One such epithelial tissue known as cuboidal epithelium lines the kidney.
Cuboidal epithelium is made up of one layer of cells which are cubical in shape and are large with a central nucleus and its function is secretion, absorption of electrolytes and important nutrients, etc. It is mainly found in the ducts of some glands, nephron tubules, Thyroid and is also present on the ovaries in females as it forms the germinal epithelium of ovaries and it is also present in seminiferous tubules of the male testes.

Cuboidal epithelium forms the lining of the proximal convoluted tubule, Henle's loop, and the Distal convoluted tubule which together forms the kidney tubule.

The cuboidal epithelium of kidney tubules also has microvilli on it which facilitates the movement of filtrate inside the tubule and the cuboidal epithelium of the bronchioles have cilia and are known as the ciliated cuboidal epithelium, The cilia facilitate easy exchange of gas in the respiratory system by blocking foreign particles entering the bronchioles.

Hence, the correct answer is Cuboidal Epithelium

Note: Epithelial Tissue are of two types,
1.Simple epithelium - It is made up of single layer and is found in body cavities, blood vessels, etc
2.Compound epithelium - It is made up of 2 or more layers and is found in the lining of the stomach, pharynx, etc
