SEROUS FLUID
CHAPTER 13
,SEROUS MEMBRANES
• Line the closed body cavities
• Pleural
• Pericardial
• Peritoneal
• Two membranes
• Parietal: lines cavity wall
• Visceral: lines organs in cavity
,FORMATION
• Purpose: provide lubrication between the two
membranes
• Ultrafiltrate of plasma
• Produced by hydrostatic and oncotic (protein)
pressure in the capillaries lining the membranes
• Normally, oncotic pressure is the same on both
sides of the membrane; hydrostatic pressure
causes the production
• Small amount of excess fluid are absorbed by
lymphatic capillaries
