RESP: Anatomy
Respiratory system anatomy and physiology.
| Question | Answer |
|---|---|
| Nostril | openings in the nose |
| Nasal cavities | space between the cranium and the roof of the mouth |
| Conchae | Fleshy lobes in the nasal cavity which increase its surface area of mucous membrane- heating & filtering air. |
| Pharynx | throat; passageway for food to the esophagus and air to the larynx |
| Larynx | voice box; passageway for air moving from pharynx to trachea; contains vocal cords |
| Epiglottis | leaf-shaped structure that closes over the larynx during swallowing |
| Trachea | The windpipe; tube leading from the larynx to the lungs; a passage through which air moves in the respiratory system |
| Bronchi | Two short branches located at the lower end of the trachea that carry air into the lungs. |
| Cilia | The hairlike projections on the outside of cells that move in a wavelike manner |
| Alveoli | tiny air sacs in the lungs where exchange of oxygen and carbon dioxide takes place |
| Right lung | 3 lobes |
| Left lung | 2 lobes with indentation that accomodates heart |
| Bronchioles | Progressively smaller airways in the lungs that lead from the bronchi to the alveoli. |
| Diaphram | Large, flat muscle at the bottom of the chest cavity that helps with breathing |
| Pleura | double-layered membrane surrounding each lung |
| Pleural Space | The thin, fluid-filled space between the two layers of the pleura; pleural cavity |
| nasopharynx | region of the pharynx at the back of the nose and above the soft palate |
| oropharynx | central portion of the pharynx between the roof of the mouth and the upper edge of the epiglottis |
| laryngopharynx | lower part of the pharynx, just below the oropharyngeal opening into the larynx and esophagus |
| hard palate | bony anterior (front) portion of the palate |
| soft palate | muscular posterior (back) portion of the palate |
| upper respiratory tract | consists of the nose, mouth, pharynx, epiglottis, larynx, and trachea |
| lower respiratory tract | consists of the bronchial tree and lungs |
| thoracic cavity (thorax) | rib cage |
| mucous membrane (mucosa) | This membrane lines passageways that open to the exterior environment. |
| mucus | slippery secretion produced by the mucous membranes that protects and lubricates these tissues |
| olfactory receptors | nerve endings that act as the receptors for the sense of smell |
| tonsils | Part of lymphatic system, help protect the body from infection coming through the nose or mouth. |
| mediastinum | area between the lungs containing the heart, aorta, venae cavae, esophagus, and trachea |
| parietal pleura | outer layer of pleura lying closer to the ribs and chest wall |
| visceral pleura | inner layer of pleura lying closer to the lung tissue |
| phrenic nerve | stimulates the diaphragm and causes it to contract |
