Respiratory
C6 Respiratory System
| Question | Answer |
|---|---|
| external respiration | inhaling air into lungs and exhaling |
| internal respiration | cellular respiration - exchange of gases between blood and tissues |
| nasal cavity | consists of mucous membranes and cilia, incoming air is filtered and warmed |
| paranasal sinuses | air spaces in skull where mucous is produced that helps to lubricate the nasal cavity |
| pharynx | throat |
| nasopharynx | contains adenoids/pharyngeal tonsils |
| oropharynx | contains palatine tonsils (lymphatic tissue) |
| laryngopharynx | handles both food and air, divides into larynx and esophagus |
| larynx | voice box |
| esophagus | carries food to stomach |
| epiglottis | cartilage flap that closes to preven food from entering larynx and trachea |
| glottis | opening to the larynx |
| palatine tonsils | lymphatic tissue at back of the roof of the mouth, or oropharynx |
| pharyngeal tonsils | adenoids in the nasopharynx, upper back wall of the throat |
| trachea | windpipe, tube of cartilage rings which divides into two bronchial tubes |
| bronchi | 2 bronchial tubes that the trachea divides into at the mediastinum |
| mediastinum | space of the chest where trachea divides into two bronchi |
| hilum | area where a bronchus, nerves, and blood vessels enter the lung |
| bronchioles | smaller tubes |
| alveoli | air sacs that facilitate the exchange of oxygen |
| pulmonary parenchyma | bronchioles and alveoli |
| 3 lobes | right lung |
| 2 lobes | left lung |
| pleura | double membrane surrounding lungs |
| visceral pleura | innermost membrane lining the lung |
| parietal pleural | outermost membrane lining of the lung, closest to ribs |
| croup | caused by infection, allergic reactions, or foreign bodies, obstructs passage of air through larynx, causing barking cough and stridor |
| stridor | harsh, high pitched sounds made during respiration |
| rales | crackles, abnormal crackling sounds when fluid, blood, or pus are in alveoli |
| rhonchi | coarse, loud rales caused by secretions in a bronchus |
| epistaxis | nosebleed |
| diptheria | bacterial throat infection |
| pertussis | whooping cough, bacterial throat infectin |
| asthma | bronchial spasms and constriction of the bronchial airways which cause dyspnea, wheezing, and coughing |
| dyspnea | labored breathing |
| bronchiectasis | chronic dilation of bronchial tubes associated with recurring lung infections |
| bronchitis | persistent inflammation of the bronchi |
| bronchogenic carcinoma | malignant tumors in bronchial pathways, can spread rapidly to the lungs |
| cystic fibrosis | inherited disease compromising the function of mucous membranes, causing obstructions (exocrine glands involved) |
| tuberculosis | caused by bacilli, producing obstructions called tubercles |
| tubercles | swellings caused by tuberculosis |
| emphysema | breakdown of alveoli walls through over-inflation causing loss of air exchange |
| pneumoconiosis | chronic condition linked to inhaling dust |
| pneumonia | inflammation and infection of alveoli producing pus, fluid, and other by-products in the lungs |
| anthracosis | black lung disease, caused by inhaling coal dust |
| asbestosis | linked to asbestos fibers |
| silicosis | caused by inhaling silica or glass |
| Grinder's disease | silicosis |
| double pneumonia | both lungs affected |
| atelectasis | collapsed lung or part of a lung, caused by trauma or blockages |
| pulmonary abscess | large collection of pus in lung caused by bacterial infection |
| pulmonary edema | swelling or buildup of fluids in bronchioles and alveoli |
| pulmonary emobolism | clot in the vessels of the lung |
| mesothelioma | tumor in the pleura |
| pleural effusion | fluid in the pleural cavity |
| pleurisy | pleuritis |
| pleuritis | inflammation of the pleura |
| pneumothorax | air or gas buildup in the pleural cavity |
| sputum | material expelled from chest area of lungs |
| spirometer | measures air intake and output |
| thoracentesis | insertion of needle or catheter into pleural cavity to obtain fluid, drain effusions, or expand a collapsed lung |
| tracheostomy | opening in the trachea if upper respiratory system damaged |
| thoracotomy | chest opened to access lungs for biopsies or resection |
| lung resection | partial or full removal of lung |
