Respitory System
| Question | Answer |
|---|---|
| Respiratory system is dvided into how many parts | 2 |
| Upper extends from? | Nose to Trachea |
| Formal name for a nostril? | Nare |
| Tip of nose is made of? | Cartalidge |
| Formal name for nose hair? | Vabrissae |
| How many Nasal cavaties are there? | 2 |
| Bone and soft tissue that separeates teh cavites is? | Nasal Septem |
| Goublet cells produce______. | Nasal Mucosa |
| 3 curly bones on each lateral wall, Superior, middle and inferior. | Nasal Conche |
| Olfactory receptors are aka | Chemo receptors |
| Air filled cavities in the frontal, maxillae, ethmoid and sphenoid bones. | Paranasal Sinuses |
| Muscular tube posterior to the nasal and oral cavites. | Pharynx |
| how many parts does the pharynx include? | 3 parts, Nasopharynx, oropharynx, laryngopharnx |
| Seperates oropharynx and nasopharynx | Soft Palate |
| Punching bag on the soft palate | uvula |
| Passes air and food. | Oral Pharynx |
| Lingual | Tongue |
| Inferior, together with oropharynx this innitiates swallowing | |
| Voice box | larynx |
| cartilage that lowers to close passage to larynx while swallowing | Epiglottis |
| vibrate to make sound waves | Vocal Chords |
| "wind pipe" | Trachea |
| no cartalidge Terminates at alvoli, circular smooth muscle | Bronchole |
| Lateral to heart, rests on diaphragm | Lungs |
| Level with Clavicle | Apex |
| the 3 pleural membranes are | Sirus membranes, parietal, and visceral |
| millions of tiny air sacs within the lung | Avoli |
| How many cell types do avoli have? | 2, |
| which type of avoli cell produces pulmonary sufactant? | Alveolar type II cells |
| What does surfactant do? | Prevents walls and alveoli from sticking togetehr by decreasing surface tension. |
| What is within the alveoli? | Macrophages |
| Alveoli are surrounded by? | Capillaries |
| Technical term for breathing? | Ventalation |
| Breathing In? | Inhilation, inspiration |
| Breathing out? | Exhalation, expiration |
| Breathing rythme is produced where? | Medulla and pons |
| Impulse to breath carried by the? | Pharnic nerve |
| Diaphragm and internal and external Intercostal Muscles make up the? | Primary muscles for breathing |
| what nerves are used for inhalation? | Phrenic and intercostal nerves |
| Capacity of the lungs to hold air | Pulmonary volumes |
| amount of air used during regular breathing | Tidal volume |
| amount of air breathed in one minute | Minute respitory volumen (mrv) |
| what you can inhale beyond tidal volume | inspritory reserve |
| what you could exhale beyond tidal volume | Exspirtory reserve |
| Sum of total Volume lungs hold | Vital Capacity |
| volume left in lungs after forced maximum exhalation | Residual air(residual volume) |
| air not in the alveoli with inhalation | antitomic deadspace |
| normal range of motion of lungs and thoracic wall for breathing | Compliance |
| process of making energy in our bodies | Cellular expiration |
| o2 in co2 out is called | internal respiration |
| How does o2 and co2 pass through capillary to alveoulus wall and back? | defusion |
| 98.5% of o2 is carried on | hemoglobin |
| How many ways do we regulate resiration? | 2 ways |
| What regulation of respiration is located in the medulla and pons? | Nervous regulation |
| Chemoreceptors also regulate respiration, it is called | chemical regulation |
