BIOL 111 Study Guide - Final Guide: Simple Columnar Epithelium, Stratified Squamous Epithelium, Simple Squamous Epithelium
Document Summary
Epithelial tissues (covers body surfaces and lines hollow organs) Simple squamous epithelium: at sites of filtration (kidneys) or diffusion (heart, lungs) and sites of secretion in serous membranes. Simple cuboidal: secretion n absorption (thyroid gland, pancreas, kidney, ovary) Noncilitiated simple columnar: lines gastrointestinal tracts and gallbladder. Mucus from goblet cells lubricate digestive, respiratory and reproductive tracts. Ciliated simple columnar epithelium: found in upper respiratory tract. Moves foreign particles trapped in mucus out of the respiratory tract. Stratified epithelium consists cells of the apical layer. Under skin n bones of developing embryo. Has a loose, irregular appearance with reticular fibers, irregularly shaped cells, and a semifluid ground substance. Give rise to all the adult connective tissues. Has fibroblasts that are imbedded in matrix containing collagen fibers. Loose connective tissue (aar, get loose mate) Consists of all 3 types of fibers , several types of cells, and a semifluid ground substance.
