Which term describes sheets of tightly packed cells that cover the inside and outside surfaces of the body?

Explanation:
Sheets of tightly packed cells that cover the inside and outside surfaces of the body are called epithelial tissue. This tissue forms the protective barriers of the skin and lines all hollow organs and body cavities, while also enabling roles in absorption, secretion, and filtration. Remember, epithelial tissue refers to the whole sheet of cells, not just a single cell (that would be an epithelial cell). Nerve tissue, by contrast, is specialized for signaling, and muscle tissue is built for contraction. Epithelial tissue can be classified by cell shape (squamous, cuboidal, columnar) and by how many layers (simple, stratified), which helps determine its specific protective or absorptive functions.
