| Nose | it has two openings, called nostrils, through which air enters. |
| Nasal septum | a wall of cartilage that separates the nose into nasal cavities. |
| nasal cavities | the two hollow spaces in the nose |
| cilia | tiny hairlike structures that help move the mucous layer that lines the airways pushing trapped particles toward the esophagus where it could can be swallowed |
| larynx | the voice box, lies between the pharynx and the trachea |
| epiglottis | a special leaflike piece of cartilage, closes the opening into the larynx during swallowing |
| pharynx | the tube or cavity, with its surrounding membrane and muscles, that connects the mouth and nasal passages with the esophagus. |
| trachea | windpipe, a tube extending from the larynx to the center of the chest |
| bronchi | where the trachea divides into two, near the center of the chest |
| bronchioles | in the lungs the bronchi continue to divide into smaller broncis |
| alveoli | resemble a bunch of grapes, made of one layer of squamas epithelial tissue and contain a rich network of blood capillaries |
| lungs | the division of the bronchi and alveoli are in the organs |
| ventilation | the process of breathing, involves two phases inspiration and expiration |
| inspiration | the process of breathing air intercoatel muscle contract enlarge thee thoracic cavity to create a vacuum |
| respiratory | when the air rushes in through the airways to the alveoli |
| expiration | air is forced out of the lungs and air passages |
| external respiratory | the exchange of oxygen and carbon dioxide between lungs and bloodstream |
| internal respiratory | the exchange of carbon dioxide and oxygen between the tissue cells and bloodstream |
| cellular respiration | cells use the oxygen and nutrients to produce energy, water, and carbon dioxide |
| apnea | lack of breathing |
| dysnea | difficult breathing |
| tachypnea | fast breathing |
| euphnea | normal quiet breathing |
| hyperpnea | abnormally increase of breathing |
| hyperventition | slow,and shallow |
| asthma | a respiratory disorder usually caused by sensitivity to an allergen such as dust, or animal fur |
| bronchitis | an inflammation of the bronchi and bronchial tubes in acute or chronic form |
| COPD | a term used to destructive any chronic lung disease that results in abstraction of the air ways |
| emphysema | noninfectious, chronics respiratory condition that occurs when the walls of the alveoli deteriorate and lose their elasticity |
| laryngitis | an inflammation of the larynx and vocal cords |
| pneumonia | an inflammation or infection of the lungs characterized by a buildup of fluid in the lungs |
