| Question | Answer |
| What is the sequence of passage through which air passes through respiriatory system | Nasal cavities-pharynx-larynx-trachea-bronchus-bronchioles-aveoli |
| Windpipe | Trachea |
| nares | nostrils |
| the opening into the larynx is the? | glottis |
| adams appple | larynx |
| right lung is divied to how many lobes | three lobes |
| left is divided into how many lobes | Two lobes |
| Each lung is covered with? | pleural membrane |
| the plueral membrane that cover the lung | visceral pleura |
| Its floor is the strong dome-shaped muscle | diaphragm |
| the movement of air into and out of the lungs | pulmonary ventilation |
| expiration | exhalation breathing out |
| inspiration | inhalation breathing in |
| the two muscles that contract during inspiration | diaphragm, external intercostals |
| what happens during inhalation | diaphrag and intercostals muscles contract - volume of chest cavity increase- lungs expand -volume of lungs increases - air pressure descreases - air move into lungs |
| what happens during exhalation | diaohragm intercostals muscles relax- volume of cavity decreases - lungs recoil -lung volume decreases - pressure in aveoli increases - air rushes out of lung |
| the movement of molecules from a region of higher concentration to region of lowe rconcentration | diffusion |
| the body uses up about how uch of inhaled oxygen | one third of oxygen |
| how many time a day do we breath and how any pounds of air | 20,000 time a day... 35 pounds |
| seals off the larynx during swallowing | epiglottis |
| the process by which cells capture energy from nutrients | celluar respiration |
| the rate of respiration is mainly determined by | carbon dioxide concentration |
| normal breathing rate for huan adult | 12- 20 miniutes |
| attachments of the diaphragm | o-xphoid process 7-12 ribs L1-L3 I- central tendon |
| demensions of the trachea | 4-4.5 inches long, 1 inch in diameter |
| helps produce sound in the larynx | arytenoid cartilage |
| forms the adams apple | thyroid cartilage |
| carbon dioxide is transported mainly in the form of | bicarbonate ions |
