Respiratory System
| Term | Definition |
|---|---|
| Adenoids | Lymphatic tissue in the nasopharynx; Pharyngeal tonsils |
| Alveolus (plural: Alveoli) | Air sacs in the lungs |
| Apex of the lung | the tip or uppermost part of the lung. |
| Apex | The tip of the structure |
| Apical | Pertaining to or located at the apex |
| Base of the lung | The lower portion of the lung |
| Basilar | Located at or in the base |
| Bronchioles | Smallest branches of the bronchi. Lead to alveolar ducts |
| Bronchus | Branch of the trachea (windpipe) that is a passageway into the lung; Bronchial tube |
| Carbon Dioxide (CO2) | gas produced by body cells when oxygen and carbon atoms from food combine; exhaled through the lungs |
| Cilia | thin hairs attached to the mucous membrane epithelium lining the respiratory tract. They clear bacteria and foreign substances from the lung. Cigarette smoke impairs the function of cilia |
| Diaphragm | Muscle separating the chest and abdomen. It contracts to pull air into the lungs and relaxes to push air out |
| Epiglottis | Lid-like piece of cartilage that covers the larynx, preventing food from entering the larynx and trachea during swallowing |
| Exhalation | Breathing out; expiration |
| Glottis | Slit-like opening to the larynx |
| Hilum of the lung | mid-line region where the bronchi, blood vessels, and nerves enter and exit the lungs |
| Inhalation | Breathing in; inspiration |
| Larynx | Voice box; containing the vocal cords |
| Lobe | Division of the lung |
| Mediastinum | Region between the lungs in the chest cavity. It contains the trachea, heart, lymph nodes, major blood vessels, esophagus, and bronchial tubes. |
| Nares | Openings in the nose carrying air into the nasal cavities; nostrils |
| Oxygen (O2) | Gas that makes up 21% of the air we breathe. Passes into the bloodstream at the lungs and travels into all body cells |
| Palatine tonsils | One pair of almond-shaped masses of lymphatic tissue in the oropharynx |
| Paranasal sinus | One of the air cavities in the skull near the nose |
| Palatine | Pertaining to the roof of the mouth |
| Parietal Pleura | Outer layer of pleura lying closer to the ribs and chest wall |
| Pharynx | Throat; Including the nasopharynx, oropharynx, and laryngopharynx |
| Pleura | Double-layered membrane surrounding each lung |
| Pleural cavity | Space between the layers of pleura |
| Pulmonary parenchyma | Essential parts of the lung, responsible for respiration; bronchioles and alveoli |
| Respiration | Exchange of gases (O2 and CO2) at the lung capillaries and at the tissue capillaries |
| Trachea | Windpipe |
| Visceral Pleura | Inner layer of pleura lying closer to the lung tissue |
| External respiration | The exchange of gasses between the external world and the lung capillaries |
| Internal respiration | The exchange of gasses between the tissue capillaries and the cells |
