  10. Severe Acute Respiratory Syndrome (SARS) - Topic Overview

    Normal lung and respiratory functionThe breathing tubes, or bronchi, leading to the air sacs (alveoli) are lined with cells that produce mucus. Normally, the cells produce a thin, runny mucus that coats the surface of the lungs.Foreign particles, such as dust and germs, constantly enter the lungs and become trapped in the mucus. Tiny hairs called cilia on the surface of the breathing tubes sweep the mucus and foreign particles upward into the larger air passages and then up to the throat where they can be swallowed or coughed up.Effects of cystic fibrosis on lung and respiratory functionCystic fibrosis causes the mucus that coats the breathing tubes to become so thick and sticky that the cilia are unable to sweep the germs and other particles up and out of the lungs. The trapped bacteria lead to frequent, serious infections and permanent lung damage.In response to infections, the body's immune system sends white blood cells to the lungs to attempt to destroy the infection.
