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.
