Membrane Coverings

• 1. Serous membrane or Serosa
• Double membrane fluid
• Cavity serous fluid reduces friction
• Organs are dynamic
• 2. Covers organs and cavity walls
• Parietal(outer) vs. visceral (clings to
  structure)
• Membrane named according to its orientation and
  organ it is a part of
• Parietal pericardium
• Visceral pleura
• Visceral peritoneum (covers abdominal organs)
