Question	Answer
Nose	nas/o
Throat	Pharyng/o Pharyngx
Windpipe	Trache/o Trachea
Main bronchial tubes	bronchi/o = bronchus brunch/o = bronchus
Small bronchial tubes	bronchiole bronchi/o -ole = small
lungs	pneumon/o pneum/o pulmonary/o
Ventilation	flow of air between the outside environment and lungs
Internal respiration vs External Respiration	Internal respiration: exchange of O2 and CO2 between blood and body tissues and cells (cellular respiration) External respiration: Exchange of O2 and CO2 @ lungs
Pathway of air during inhalation	nose → nasal cavity → nasopharynx → oropharynx → laryngopharynx → larynx → trachea → bronchi → bronchioles → alveoli → lung capillaries
Upper Respiratory tract	- nose (nares and nasal septum) - nasal cavity (olfactory system) -Paranasal sinuses -pharynx (nasopharynx, oropharynx, laryngopharyx) - Larynx (epiglottis, glottis)
Lower Respiratory Tract	- Trachea - Lungs and associated structures (bronchi, bronchioles, alveoli, lung capillaries)
Where would you find a septum in the respiratory tract?	Nasal cavity is divided down the middle by the nasal septum, a cartilaginous plate
What structure divides the mouth from the nose?	Palate in the roof of the mouth
Where would you expect to find mucous membranes in the respiratory system?	Walls of nasal cavity and nasal septum
What are the three divisions of the pharynx based on their locations?	1. Nasopharynx 2.Oropharynx 3. Laryngopharynx
