Respiratory System (Chapter 9) Part 1. Describe structure and function of each of these terms (in great detail...read the pages in the book from 170 to 174) in this order (the pathway of air from the nasal cavities to the lungs). Inserting a picture of your respiratory system would be nice.

Nasal cavity-Filters, warms, and moistens air Pharynx-Passageway where pathway for air and food cross Glottis-Space between the vocal chords Larynx-Produces sound Trachea-Passage of air to bronchi Bronchus-Passage od air to lungs Bronchioles-Passage of air to alveoli Lung-Contains alveoli/ carries out gas exchange Diaphragm-Skeletal muscle, functions in ventilation Part 2. Describe the structure and function of alveoli in great detail. (Inserting a picture of an alveolus would be nice.) The lungs have about 300 million alveoli. Each alveoli is surrounded by blood capillaries. This is where gas exchange occurs

Part 3. (p. 178) Describe in great detail how Carbon Dioxide is carried in the blood and how Oxygen is carried in the blood.

Part 4. Describe 4 respiratory disorders of your choice (in great detail). Sinusitis-develops when nasal congestion blocks the tiny openings leading to the sinuses. Otitis Media-infection of the middle ear. Infection can spread by way of the auditory tube. Tonsillitis-Occurs when the tonsils become enlarged and inflamed. Larygitis-infection of the larynx with accompanying hoarseness, leading to the inability to talk in an audible voice.
