  1. 1. PowerPoint® Lecture Slide Presentation by Patty Bostwick-Taylor, Florence-Darlington Technical College Cells and Tissues 3 PART C Copyright © 2009 Pearson Education, Inc., publishing as Benjamin Cummings
  2. 2. Epithelial Tissues  Locations  Body coverings  Body linings  Glandular tissue  Functions  Protection  Absorption  Filtration  Secretion Copyright © 2009 Pearson Education, Inc., publishing as Benjamin Cummings
  3. 3. Epithelium Characteristics  Cells fit closely together and often form sheets  The apical surface is the free surface of the tissue  The lower surface of the epithelium rests on a basement membrane  Avascular (no blood supply)  Regenerate easily if well nourished Copyright © 2009 Pearson Education, Inc., publishing as Benjamin Cummings
