Verified step by step guidance

Understand the function of each type of membrane: Cutaneous membranes cover the body surface, synovial membranes line joint cavities, serous membranes line closed internal body cavities, and mucous membranes line body cavities that are open to the exterior.

Identify the characteristics of mucous membranes: These membranes secrete mucus, which helps to protect and lubricate the surfaces they cover. They are found lining the respiratory, digestive, urinary, and reproductive tracts.

Consider the locations where mucous membranes are found: They are present in areas such as the nasal passages, mouth, lungs, stomach, and intestines, all of which are open to the external environment.

Compare the functions and locations of the other membranes: Cutaneous membranes are the skin, synovial membranes are found in joints, and serous membranes are found in closed cavities like the thoracic and abdominal cavities.

Conclude that mucous membranes are the ones that line body cavities open to the exterior, based on their function and location.
