Tissues, Part 2 - Epithelial Tissue: Crash Course A&P

The video explains the role of epithelial tissue in organizing and protecting the body. It covers the types of epithelial tissue, including proper and glandular epithelium, and their functions. The video describes the shapes of epithelial cells—squamous, cuboidal, and columnar—and their correlation with function. It also discusses the layering of epithelial tissue, such as simple, stratified, and pseudostratified, and the importance of cell polarity and permeability. Finally, it highlights the role of glandular epithelium in secretions and concludes with a summary of key points.
