Epithelial Tissue Characteristics and Functions

This video from Moomoomath and Science discusses epithelial tissues, which line cavities and cover surfaces of vessels and organs. These tissues serve functions such as protection, secretion, absorption, and sensation. Epithelial tissues are classified by shape—squamous, cuboidal, and columnar—and by layers—simple and stratified. The video concludes with a reminder to subscribe for daily math and science content.
