Which type of membrane supports internal organs and compartments large cavities?

The correct answer is serous membrane, which is specifically designed to line and support the internal organs and compartments within body cavities, particularly those that are not open to the exterior environment. Serous membranes are composed of a layer of simple squamous epithelium and a layer of connective tissue. They secrete a lubricating fluid (serous fluid), which reduces friction between the organs and the cavity walls as they move against each other, such as the heart in the pericardial cavity or the lungs in the pleural cavity.

In contrast, the meninges membrane refers to the protective coverings of the central nervous system, specifically the brain and spinal cord. The cutaneous membrane is the skin, which serves as a barrier to the external environment but does not support internal organs. Mucous membranes line body cavities and passages that open to the exterior, such as the respiratory and digestive tracts, and they secrete mucus to keep these surfaces moist; however, they are not designed for supporting large cavities in the way serous membranes are.
