Membranes line things.
Serous membranes are thin mesothelium (simple squamous epithelial) layers that line cavity walls and the viscera (organs lying in the thoracic and abdominalpelvic cavities).
Parietal layer lines the walls.
Pleural layer covers the organs.
Between the parietal and pleural layer, serous membranes have serous fluid that acts as a lubricant to reduce friction.
