- the respiratory system
- 3 basic processes
- Breathing- INSPIRATION and EXPIRATION of air between the atmosphere and the lungs
- external respiration- exchange of gases between the lungs and the blood
- internal respiration- exchange of gases between the blood and cells
- two systems supply O2 and eliminate CO2
- Respiratory- organs that exchange gases between the atmosphere and the blood
- nose
- pharynx
- larynx
- trachea
- bronchi
- lungs
- cardiovascular- transports the gases between the lungs and the cells
- Respiratory- organs that exchange gases between the atmosphere and the blood
- devisions of the respiratory tract
- respiratory tract- passageways through which air will move
- upper respiratory tract- all structures superior to the laryx
- lower respiratory tract- larynx and all structures below
- the respiratory epithelium
- Pseudo-stratified ciliated columnar epithelium with lots of goblet cells (secrete mucus)
- lines the upper respiratory system
- cilia are present and beat which moves the mucus up and out of the passageways or into the throat where it is swallowed
- nasal cavity- capillaries under epithelium warm air as it enters and mucus moistens incoming air
