Question: 1 / 400

What type of tissue is epithelial tissue?

A tissue that provides support for the body

A body tissue that covers surfaces inside and out

Epithelial tissue is characterized as a body tissue that covers surfaces both inside and out. This type of tissue serves several crucial functions, including protection, absorption, secretion, and sensation. It forms the outer layer of the skin, as well as lining internal organs and cavities, which highlights its role in covering and protecting body surfaces while also allowing for interaction with the environment.

Epithelial tissue is unique because it has minimal extracellular matrix, with cells tightly packed together, providing a barrier that can regulate permeability. This differentiates it from other types of tissues, such as connective tissue, which primarily supports and anchors different structures within the body. Understanding the distinct role of epithelial tissue helps clarify its importance in overall body function, especially in areas where protection and selective absorption are needed.
