Little hairs called Cilia, which help filter dust from the air as it passes into the lungs.
The upper respiratory tract is lined with stratified squamous epithelium
In humans motile cilia are found in the lining of the trachea (windpipe), where they sweep mucus and dirt out of the lungs.

Mucous Membrane
Are mucous membranes sterile
digestive system is lined inside by non-keratinised stratified squamous epithelium some of which are ciliated
alveoli
I would assume IgA class antibodies. The intestinal tract is lined with mucous membranes and the IgA class is primarily secreted through mucous.
believe it or not, mucous membranes secrete mucous. It helps protect the respiratory system (or whichever system the mucous membrane you're referring to is in).
