Verified step by step guidance

Understand the function of each type of membrane: Serous membranes line closed cavities and cover organs within these cavities. Cutaneous membranes refer to the skin, covering the body surface. Synovial membranes line joint cavities and produce synovial fluid. Mucous membranes line body cavities that open to the exterior.

Identify the key characteristic of the problem: The question asks for the type of membrane that lines body cavities open to the exterior.

Recall the definition of mucous membranes: Mucous membranes are epithelial tissues that secrete mucus and line many body cavities and tubular organs including the gut and respiratory passages.

Consider examples of body cavities open to the exterior: These include the respiratory tract, digestive tract, and urogenital tracts, all of which are lined by mucous membranes.

Conclude that mucous membranes are the correct answer as they specifically line body cavities that are open to the exterior, providing a protective barrier and secreting mucus to trap pathogens and particles.
