Current Question (ID: 13724)

Question:

This epithelial tissue is found in ducts of glands and tubular parts of nephrons in kidneys. Its main functions are secretion and absorption. Choose the correct option

Options:

1. simple epithelium
2. Simple cuboidal epithelium
3. Simple columnar epithelium
4. Ciliated epithelium

Solution:

Simple cuboidal epithelium is a type of epithelial tissue that is composed of a single layer of cube-shaped cells. It is found in ducts of glands and tubular parts of nephrons in kidneys, where its main functions are secretion and absorption. The cuboidal shape of the cells provides a larger surface area for these functions. The cells are connected to each other through tight junctions, which prevent the leakage of fluids between cells. Simple cuboidal epithelium can be found in various organs, including the pancreas, salivary glands, and thyroid gland.
