• The structure of Epithelia consists of what?

  one/more layers of cells connected to one another
• It is a thin layer of extracellular matrix between epithelial cells and underlying tissues. What type of tissue STRUCTURE is this?

  Epithelia
• The Basal Lamina or Basement membrane are composed of what?

  Network Collagen laminin filaments embedded in Proteoglycans
• What type of protein is where the Basal lamina is embedded in?

  Proteoglycans
• What are the 2 general types of Epithelial tissues?

  sheets of tissues that lie on surface of body or that line the inside of tubes & hallow organs

  Secretory epithelia that synthesizes and releases substances in the extracellular space
• How to classify sheet epithelia?

  number of cell layers in tissue

  shape of cells in surface layer
• One thick layer. what is this?

  Simple
• Multiple cell layers. What is this?

  Stratified
• ”3 cell shapes”. What is this?

  Squamous, Cuboidal, and Columnar
• What are cappilaries?

  delicate blood vessels in body
• What are the 5 functional types of epithelia?

  Exchange, Transporting, Cilliated, Protective, and Secreted
• It allows movement through between cells. What functional type of epithelia is this?

  Exchange
• Where can I find the exchange epithelia in a human body?

  Blood vessels and Lungs
• They are a very thin and flattened cells. What functional type of epithelia is this?

  Exchange
• It lines blood vessels and lungs. What functional type of epithelia is this?

  Exchange
• What are the 2 major sites of gas exchange in the body?

  Blood vessels and Lungs
• It selectively moves substances between Lumen and ECF, like ions and nutrients. What functional type of epithelia is this?

  Transporting
• Do Transporting Epithelium SELECTIVELY moves substances between lumen and ECF, like ions and nutrients or NO?

  Selectively
• Where can I find the Transporting epithelium in a human body?

  Intestinal Tract and Kidney
• What does ABSORPTION do?

  Movement of material from external environment to internal environment.
• What does Secretion do?

  Movement in opposite direction, from internal to external environment
• They are primary located in the AIRWAYS of RESPIRATORY SYSTEM and FEMALE REPRODUCTIVE TRACT. What functional type of epithelia is this?

  Cilliated
• Where can I find the Cilliated epithelium?

  Respiratory system and female reproductive tract
• What is the function of Cilliated Epithelium?


  Beating Cillia creates fluid currents and sweeps across epithelial surface
• Where can I find the protective epithelium?

  Surface of the body and inside opening of body cavities
• They have many stacked layers of cells that are constantly replaced. What functional type of epithelia is this?

  Protective
• What do secretory Epithelium does?

  Synthesize and release secretory products into external environment on in the blood
• Where can I find the Secretory epethelium?

  GRRID (Glands, Repiratory, Reproductive, Integument, and digestive tract)
• What does Goblet cells do?

  Secrete mucus into the Lumen of Hollow organs
• Exocrine cells produces what?

  Mucus
• What are Exocrine glands?

  Releases secretions to body’s external environment
• Location of Exocrine glands?

  Surface of skin, epithelial lining of internal passageways like; airways of lungs or lumen of intestines
• What are the 2 types of Exocrine secretions?

  Serous and Mucous
• What is a serous secretions?

  Watery solutions
• What is a Mucous secretions?

  Sticky solutions
• It contains glycoproteins and proteoglycans. What type of exocrine secretions is this?

  Mucous
• “Many maintains enzymes”. What type of Exocrine secretion is this?

  Serous
• Give me examples of Serous secretions?

  Tears, Sweat, digestive enzyme solutions
• Give me examples of Mucous secretions?

  Salivary glands release mixed secretions
• Salivary glands release mixed secretions, some of them also contains more than one secretion. What is it?

  Serous and Mucous
