The respiratory system
Major structures
•Nose -------- nas/o
•Sinuses ------ sinus/o
•Epiglottis ------ epiglott/o
•Pharynx -------- pharyng/o
•Larynx --------- blaring /o
•Trachea ------- trache/o
•Brocnchi ------- bronch/o, bronchi/o
•Alveoli -------- alveoli/o
•Lungs ------ pneum/o
Functions of the respiratory system:
•Bring oxygen rich air into the body for delivery to the blood cell.
•Expel waste products (carbon dioxide and water).
•Produce the air flow through the larynx that makes speech possible.
Structure of the respiratory system
It is consist of
A. The upper respiratory tract consist of
1)Nose which contain
•nasal cavity
•nasal septum
•Mucous membrane (mucus, cilia, olfactory receptors).
2- Mouth which contain
•Tooth
•Tongue
•Gum
3-Pharynx which contain
•Nasopharynx
•Oropharynx
•laryngopharynx
4- epiglottis which contain
•orophaynx and laryngopharynx
•Epiglottis
5-larynx which contain
•voice box
•Larynex
•glottis
6- trachea which contain
•windpipe or airway
•mucous membrane lining with cilia
•smooth muscle with c-shaped cartilage rings
•divided into tow branches
•no gaseous exchange
B. The lower respiratory tract consist of
•bronchial tree
•lungs
