Document Summary
Lowest level that can live as an organism is a cell. Vertebrates have many different cell types that are put together in different ways. Tissues are groups of cells that have a similar structure and function. Cells in tissues are held together by an extra cellular matrix, or are woven together. Found in skin, lines respiratory tract, digestive tract, and other ducts in the body. Skin is a good barrier because of these densely packed cells, prevents microorganisms from entering the body, helps prevent injury and helps you retain water. Different kinds of epithelial tissue which vary in form. Have their own types of specialized cells, i. e. in respiratory tract cells produce mucus. Extracellular matrix can be a liquid, jelly-like or solid. Loose connective tissue: binds epithelium to tissue below, suspends organs in body cavity. Fibrous connective tissue: fairly dense fibers, has some stretch to it, ex.
