Differences:
1) Position -- Mucous membranes line cavities that connect with the exterior, including the digestive, respiratory, reproductive, and urinary tracts.
Serous membranes line the sealed, internal cavities of the body.
There are three such membranes with each consisting of a simple epithelium supported by loose connective tissue:
the pleura lines the pleural cavities and covers the lungs
the peritoneum lines the peritoneal cavity and covers the surfaces of enclosed organs such as the liver and stomach
the pericardium lines the pericardial cavity and covers the heart.
2) Function -- Mucous membranes protect the tracts from mechanical factor, chemical substances, and microorganism invasion.
Serous fluid covers the surfaces to minimize friction between opposing surfaces.
3) Types -- Mucous membranes: simple epithelia, stratified squamous epithelium, the transitional epithelium
Serous membranes: there are parietal and visceral portions. Parietal lines the outer wall of the internal chamber. The visceral portion covers organs within the body cavity.
Similarities:
1) They are kept moist at all times.
2) They are meant to protect
