| Cilia | hairlike projections on the outer surface of certian cells that trap and move particles up and down the throat |
| Goblet Cells | produce mucus |
| Mucus | moistens the air and traps incoming particles |
| Pharynx | AKA Throat, shared with the digestive system |
| Larynx | AKA voice box, contains epiglottis, cricoid & thyroid (Adams Apple) |
| Eppiglottis | "Guardian of the airways" |
| Bronchi | Large air conduction passegways leading from the treachea to each lung |
| Bronchioles | Like roots of a tree, these are smaller divisions of the Bronchi |
| Alveoli | Tiny sacs attatched to the distal ends of the bronchioles |
| Surfactants | phospholipids that assist in the exchange of gas in the alveoli, reduce surface tension & contribute to the elasticity of pulmonary tissue |
| Lungs | Spongy, light, elastic, paired organs of respiration |
| Respitory Diaphragm | A dome shaped muscular partition that seperates the thoracic cavity from the abdominal cavity |
| Breathing | AKA Pulmonary ventilation, the mechanical process of moving air in and out of the body |
| Inspiration | process responsible for drawing air into the lungs |
| Expiration | Process responsible for expelling air from the lungs back to the atmosphere |
| External (pulmonary) respiration | Gas exchange in the lungs, between blood and air in the aveoli that came from the external environment |
| Internal (tissue) repiration | Gas exchange between blood and the body's tissues |
