 Parietal & visceral peritoneum are continuous with each other.  They can reflect from the wall to organ or from one organ to another organ.  These reflections may form many structures  They hold organs in position & convey N,A,V. & Ln. to viscera Lesser omentum Transverse colon greater omentum Transverse mesocolon Mesentery Small Pariatal peritoneum interstine Peritoneal cavity Viceral peritoneum Introduction to the peritoneum
