Video 5 Notes: Specialized Cells in the Breathing System

·         The nose and air passages are lined with mucous membrane which produces mucous

·         Mucous traps dirt and germs from the air you breathe

·         Cilia are tiny hairs that move the mucous and germs to the back of your throat where it is swallowed

·         Mucous and Cilia keep the lungs clean and reduces chances of infection
