| Question | Answer |
| alveoli | air sacs at the end of the bronchioles
-surrounded by capillaries that allow oxygen and CO2 to be exchanged between the blood and lungs |
| Hyperpnea | Increased rate and depth of breathing |
| Hypoxia | Decreased amounts of oxygen to tissues |
| Trachea | -windpipe
-carries air from the pharynx to the bronchi
-subdivides into two bronchi, each entering one lung |
| larynx | -voice box
-contains vocal cords |
| Nasopharynx | -upper portion of larynx
-contains pharyngeal tonsils(adenoids)
-located behind the nose |
| Oropharynx | -middle portion of pharynx
-contains the palatine tonsils
-located behind the mouth |
| Epiglottis | flap of cartilage that covers the larynx to prevent aspiration |
| cellular respiration | the use of oxygen and nutrients to produce energy, water, CO2, and heat |
| Epistaxis | nosebleed |
| dyspnea | painful or difficult breathing |
| Bronchioles | smallest subdivision of the bronchi |
| Tachypnea | rapid shallow breathing |
| asthma | obstruction of the bronchiole
S&S:-coughing
-wheezing
-dyspnea
RX:-bronchodilator
-anti-inflammatory
-oxygen |
| function of the nose | warm, filter, and moisten air passing through |
| nasal septum | seperates the nasal cavities |
| respitory system | to take in oxygen needed for body cells and remove CO2 |
| internal respiration | exchange of oxygen and CO2 between the blood and body cells |
| external respiration | exchange of oxygen and CO2 between the blood in capillaries surrounding alveoli |
| diaphragm | major muscle of respiration
-divides the thoracic cavity and the abdominal cavity |
| ventilation | the process of breathing
inspiration: taking in air
expiration: when air is forced out of the lungs |
| lungs | right lung contains 3 lobes
left lung contains 2 lobes |
| pleura | serous membrane that covers the lungs to prevent friction when lungs expand and contract |
| sinuses | cavities in the skull that warm and moisten air and provide resonance to the voice |
| pharynx | (the throat)
divided into three portions
upper portion is the nasopharynx
middle portion is the oropharynx
lowest portion is the laryngopharynx |
