Study Notes

Mesothelium Structure and Function

  • Mesothelial cells form the mesothelium, which lines body cavities and organs.
  • Beneath the mesothelial cells is a thin layer of fibrous connective tissue containing lymphatic vessels and capillaries.
  • Mesothelium consists of two distinct layers:
    • Parietal Layer: Lines the walls of body cavities.
    • Visceral Layer: Covers the surfaces of internal organs.
  • The primary function of the mesothelium is to produce serous fluid, which serves as a lubricant.
  • Serous fluid facilitates organ movement within the body cavity, essential for functions like heartbeats, bowel movement, and lung expansion/contraction.
