Document Summary

What does the respiratory system do: passageway for o2 into the body, passageway for co2 out of the body, helps regulate ph (7. 4, speech, maintain air quality, dissolve clots. Lungs are divided into left and right lobes. Pharynx divides into two: esophagus, larynx (vocal cords) Conducting zone determines air flow (lined with cilia that secrete mucus: trachea, bronchi, bronchioles, terminal bronchioles, air slows down by terminal bronchioles which allows for effective gas exchange, low resistance pathway, which warms, humidifies and filters air. Respiratory zone allows for gas exchange: respiratory bronchioles (lined with cilia that secrete mucus) , alveolar ducts, alveolar sacs. Change the rate of air flow: increase rate of breathing, increase the depth, alter the radius of the airways. Cystic fibrosis: too much mucus production from the conducting zone down to the respiratory bronchioles. Gas exchange occurs in the alveoli, which are lined with epithelial cells.
