Simple Columnar Epithelium

• Simple Columnar Epithelium are layer of called that are what than they are wide?

  Taller
• Simple Columnar Epithelium lines the WHAT where it ABSORBS nutrients from the lumen of the intestine?

  Small intestine
• Simple Columnar epithelium are LOCALIZED where?

  Stomach
• In the stomach, the simple columnar epithelium secretes what?

  Acid, digestive enzymes, and mucus
• In simple columnar epithelium, what are the 2 responsible for absorption?

  Cilia and microvilli
• Give the 4 locations of SIMPLE COLUMNAR EPITHELIUM?

  Stomach, small intestine, large intestine, and 3rd part of the esophagus
• Villi: Thin, finger-like projections that increase the surface area of the small intestine
• What are the 2 cell types of simple columnar epithelium?

  Absorptive cells and goblet cells.
• Goblet cells: pale-staining secretes mucus
• Gastro-esophageal juction: thin connective tissue basement membrane separates the surface epithelium from the underlying collagen fibers and cells of the connective tissue
• In the OVIDUCTS, ciliated cells dominate and serve to move the ovum away from the ovary and toward the uterus.
• The NON-CILIATED SECRETORY CELLS of OVIDUCTS, are also called as PEG CELLS, release a secretion that lubricates the tube and provides nourishment and protection to the traveling ovum.
• In GALLBLADDER the epithelial cells have microvilli.
• In GALLBLADDER, Underneath the epithelium is the LAMINA PROPRIA.
• Instead of being smooth, the inside of the intestine is folded and covered by millions of tiny projections called VILLI.
• In the small intestine GOBLET CELLS are located within the surface epithelium and secrete mucus.
