Final answer:
Mucous membranes are found in the genitals among other areas like the respiratory, digestive, and urinary tracts. These membranes secrete mucus that helps trap and remove pathogens from the body.
Step-by-step explanation:
Mucous membranes are found in various parts of the body, specifically in areas where they provide a mechanical barrier to pathogens. Mucous membranes are located in the digestive, respiratory, urinary, and reproductive tracts, and one of the body parts where they are found is the genitals (C).
These membranes are essential as they secrete mucus, which traps pathogens and aids in their removal from the body through mechanisms like sneezing and coughing. Mucosal surfaces are vital for protecting body openings against microbial entry, making them a significant part of the immune response.
