It is found in body structures where _2_, _3_, and _4_ occur. 1. one 2. absorption 3. secretion 4. filtration Stratified epithelium has more than one layer of cells and serves as . protection Connective tissue is found the body; it serves to different structures of the body. throughout, connect Connective tissue commonly has its own ; however, there are some types of connective tissue, such as , that do not. blood supply, ligaments 4 examples of connective tissue 1. bone 2. cartilage 3. adipose (fat) 4. blood vesse
