- simple columnar epithelium
- high volume secretion; found in digestive tube; makes exocrine glands
- stratified squamous
- top layer is flat but other layers may not be; can be keratinized or not; covers surfaces needing protection; cells bound tightly together
- simple squamous
- found in alveoli of lungs; lining of blood vessels (endothelium); lines body cavities' is osmosis & diffusion
- stratified cuboidal epithelium
- found in sweat & salivary glands
- non-keratinized stratified squamous epithelium
- must be kept moist by bodily secretions to prevent drying out; found in cornea, oral cavity, vagina, rectum, esophogus
- glandular epithelium
- made up of cells that produce secretions classified as endocrine or exocrine; number of gland cells & nature of secretion; example is columnar epithelium with goblet cells
- stratified columnar epithelium
- rare epithelium found in large duct of salivary gland; found in between stratified squamous and pseudostratified
- endocrine gland
- cells that secrete hormones directly into the bloodstream
- multicellular glands
- have many cells that may form a secretory sheet of epithelium in the linings of stomach & uterus
- simple cuboidal epithelium
- fx: ion pumping; absorption, secretion, protection; found in ovaries, thyroid gland, kidney tubules;
- stratified layer
- 2 or more cell layers, only the deepest layer touches the basement membrane
- squamous shape
- flat, irregular-shaped cells
- keratinised stratified squamous
- kept moist by keratin; found in skin, tongue & external portion of lips
- epithelial tissue
- sheets of cells covering exposed surfaces, line body cavities, ducts, vessels
- unicellular glands
- type of gland; example: mucus secreting goblet cells; found in epithelium of respiratory & intestinal tract
- columnar epithelium
- tall, thin cells; taller than is wide; grouped by nonciliated & ciliated
- cellularity
- cells closely bound to each other by cell junctions making a wide sheet
- mucous glands
- most are multicellular with exception to unicellular goblet cells
- pseudostratified
- 1 cell layer but appears to be multiple due to irregular shape
- serous glands
- cell type that produce a thin, watery protein rich secretion; found in all cavity linings of pericardial, pleural & pericardial
