Document Summary

Respiratory system: organ system that takes in air and expels it from the body. Gas exchange: o2 and co2 between blood and air. Pressure gradients btwn throax and abdomen promotes flow of lymph and venous blood. Blood filtration: filter small blood clots from blood stream. Conducting division: passages that serve only for airflow. Respiratory division: aveoli and other gas-exchange regions of distal airway. Warms, cleanses, humidifies inhaled air, detects odors, resonating chamber that amplifies voice. Covers small area of the roof of the nasal fossa and adjacent parts of the septum and superior concha. Muscular funnel from posterior nasal apertures -> larynx. During swallowing, epiglottis closes airway and directs food and drink into esophagus. Stratified squamous epithelium to endure vibration and contact between cords. Reinforce trachea and keep it from collapsing when you inhale. Allows room for the esophagus to expand as swallowed food passes by.
