resp system chapt#13
2nd term resp. system
| Question | Answer |
|---|---|
| components of upper resp. tract | nose, sinuses, trachea, larynx |
| airfilled cavities on head or skull | sinuses |
| lung infection caused by virus, bacteria, fungus | pneumonia |
| lung ruptures and air escape | pneumothorax |
| control center of brain | medulla oblongata |
| ear sacs surrounded by capillaries | alveoli |
| covering our opening of larynx to prevent food from entering the lung | epiglottis |
| infectious disease can lay dormant for yrs | tuberculosis |
| body reacts to an allergy causes restriction of airway | asthma |
| mass of undesolved matter can be present in lymph or blood | embolism |
| windpipe; reaches center of chest | trachea |
| slippery liquid between pleural layers | pleural fluid |
| passage way to middle of ear | eustachian tube |
| group of diseases makes it to difficult to get air in and out of lung | COPD: chronic obstructive pulmonary disease |
| voicebox composed of cartilage | larynx |
| membrane connects cardiovascular & respiratory | alveolar-capillary membrane |
| oxygenated blood transports through cardiovascular system to cells & tissues where gases are exchanged | internal respiratory |
| pus in the pleural cavity | empyema |
| incomplete of expansion or collapse of all/part of lung | atelectasis |
| excessive buildup of fluid in pleural space | pleural effusion |
| network of small blood vessels | capillaries |
| airways get inflammed & sputum is produced | bronchitis |
| irreversible damages air sac | emphysema |
| resp. system primary job | to bring oxygen from the atmosphere into the bloodstream and to remove gaseous waste by product carbon dioxide |
| ventilation | movement of air where actual gas exchange takes place with the blood stream |
| respiration | process of gas exchange, oxygen is added to the blood stream and carbon monoxide is removed |
| external respiration | when the gas exchange in the lungs occurs between blood and the air in the external atmosphere |
| sense of smell | ability to taste |
| 3 main regions of the space behind the nose | vestibular, olfactory, respiratory region |
| 3 sections of pharynx(the throat) | nasopharynx, oropharynx, laryngopharynx |
| adams apple | larger in men than in women |
| trachea extends to what vertebrae | 6th cervical vertebrae |
| lungs are housed where | the thoracic cavity and seperated by the mediastinum |
| right lung base contains how many lobes | 3 lobes |
| left side contains how many lobes and why | 2 lobes due to the heart taking up space of the left lung |
| what sends the signal to the diaphragm | phrenic nerve |
| external intercostal muscles | assist by moving the ribs up and outward during inspiration to increase total volume in the thoracic cavity |
| what is more passive | exhalation |
| movement of oxygen and carbon dioxide in and out of the respiratory system | oxygen rich air from enviroment, nasal cavity, pharynx, trachea, bronchi, bronchioles, aveoli, capillaries then bronchioles, bronchi, trachea, pharynx, nasal cavity, carbon dioxide rich air to the environment |
