Verified step by step guidance

Understand the function of each type of membrane: Mucous membranes line body tracts that open to the exterior and secrete mucus to keep the tissue moist and protected.

Identify the locations where mucous membranes are found: These membranes are typically found lining the respiratory, digestive, urinary, and reproductive tracts.

Differentiate between the types of membranes: Serous membranes line closed cavities and cover organs within these cavities, cutaneous membranes refer to the skin, and synovial membranes line joint cavities.

Consider the environment each membrane is exposed to: Mucous membranes are specifically adapted to environments that are exposed to the external environment, providing a barrier and secretion function.

Conclude that the mucous membrane is the type that lines body tracts opening to the exterior environment, based on its function and location.
