Question

besides acting as mechanical barriers, the skin epidermis and mucosae of the body have other attributes that contribute to their protective roles. Cite the common body locations and the importance of mucus, lysosome, keratin, acitd ph, and cilia.

Answer 1

The skin and mucosae of the body have other attributes that contribute to their protective roles besides acting as mechanical barriers. They secrete mucus, contain keratin, have acidic pH, and possess cilia.

Step-by-step explanation:

The skin and mucosae of the body have other attributes that contribute to their protective roles besides acting as mechanical barriers. The skin contains the protein keratin, which resists physical entry into cells. Mucous membranes secrete mucus, a slimy substance that traps pathogens. The openings of the body, such as the nose and ears, are protected by hairs that catch pathogens, and the mucous membranes of the upper respiratory tract have cilia that constantly move pathogens trapped in the mucus coat up to the mouth.
