tissues

• simple squamous epithelium


  ~usually forms membrane~lines body cavities~lines lungs and capillaries
• simple cuboidal epithelium


  ~common in glands and their ducts~forms walls of kidney tubules~covers the ovaries
• simple columnar epithelium


  ~often includes goblet cells, which produce mucus~lines digestive tract
• pseudostratified


  ~sometimes ciliated, such as in the respiratory tract~may function in absorption or secretion~nuclei are at different heights
• stratified squamous


  ~Found as a protective covering where friction is common~∙ Can be keratinized or non-keratinizedLocations ∙ Skin ∙ Mouth ∙ Esophagus
• Transitional epithelium


  ~Shape of cells depends upon the amount of stretching~∙Lines organs of the urinary system
• Gland


  one or more cells that secretes a particular product
• Two major gland types

  ~Endocrine gland~Exocrine gland
• Endocrine gland


  ~Ductless~Secretions are hormones
• ∙Exocrine gland

  ~Empty through ducts to the epithelial surface~Include sweat and oil glands
• simple squamous


  ~air sacs of lungs, walls of capillaries, linings of blood and lymph vessels~diffusion, filtration, osmosis, covering of surfaces
• simple cuboidal


  ~ovary surfaces, kidney tubule linings, linings of ducts and certain glands~absorption and secretion
• simple columnar


  ~intestine, stomach, uterus linings~absorption, protection, secretion
• pseudostratified columnar

  ~respiratory passage linings~movement of mucus, protection, and secretion
• stratified squamous


  ~outer layer of skin, linings of anal canal, oral cavity, throat, and vagina~protection
• stratified cuboidal


  ~linings of larger mammary gland ducts, pancreas, salivary glands, and sweat glands~protection
• stratified columnar


  ~part of the male urethra and parts of the pharynx~protection and secretion
• transitional epithelium


  ~inner urinary bladder lining, linings of ureters, and part of urethra~distensibility and protection
• glandular epithelium

  ~endocrine, salivary, and sweat glands~secretion
