Respiratory
A&P Exercise 50 & 51 ; Respiratory
| Question | Answer |
|---|---|
| What does the respiratory system involve? | movements of oxygen from the external environment eventually to our cells, and the movements of carbon dioxide produced by out cells until it exits our body. |
| What is the pulmonary ventilation? | Breathing |
| What are the structures that serve as passageways for gases into and out of the lungs? | nose, nasal cavity, paranasal sinuses, pharynx, larynx, trachea, and bronchial tree |
| What is external respiration? | The exchange of carbon dioxide in the lungs |
| What is internal respiration? | The exchange of oxygen and carbon dioxide in the tissues |
| The blood transports gases to and from the _____ and the body cells. | Alveolar sacs |
| What does the goblet cells secret on the epithelial lining of the respiratory tubes? | Protective mucus |
| What does the cilia that extend into the mucus do? | Creates a current of mucus that moves any entrapped debris toward the pharynx. |
| The right lung has how many lobes? | 3 |
| The left lung has how many lobes? | 2 |
| What does the hilum of the lung represents? | an area where the bronchus and major blood vessels are located. |
| What adheres to the surface of each lung, including the fissures between the lungs? | Visceral pleura |
| What covers the internal surface of the thoracic wall and the superior surface of the diaphragm? | Parietal pleura |
| What is the narrow potential space that is located between the two pleurae and contains pleural fluid? | Parietal cavity |
| What serves as lubrication during breathing movements, and due to surface tensions, resists respiration of the pleurae? | Pleural fluid |
| What is the hollow space behind the nose? | Nasal cavity |
| What is the external opening into the nasal cavity? | naris/nostril |
| What divides the nasal cavity into right and left portions? | Nasal septum |
| What increases surface area and air turbulence during breathing? | Nasal conchae |
| What are the air passageways along the nasal conchae? | Nasal meatus |
| What is the air-filled spaces that open into the nasal cavity and is lined with the mucous membrane? | Paranasal sinuses |
| What is often called the throat? | Pharynx |
| What section of the pharynx is an air passageway only? | Nasopharynx |
| What are the two section of the pharynx that is a passageway for air and food? | Oropharnyx and Layngopharynx |
| What is the airway enlargement superior to the trachea? | Larynx |
| The vocal cords consists of two folds. What fold is the upper folds but does not produce sounds? | The vestibular folds |
| What is another name for the vestibular folds? | False vocal cords |
| The vocal cords consists of two folds. What fold vibrate when exhaling to produce sounds | Vocal folds. |
| What is another name for vocal folds? | True vocal cords |
| What is the "Adam's Apple?" | The thyroid cartilage |
| What is the largest hyaline cartilage of the larynx that is covered by part of the thyroid gland? | The thyroid cartilage |
| What is the complete ring of hyaline cartilage of inferior larynx? | Cricoid cartilage |
| What connects thyroid and the cricoid cartilages? | Cricothyoid ligament |
| What covers part of the larynx opening during swallowing? | Epiglottis |
| What is the elastic cartilage supporting epiglottis? | Epiglottis cartilage |
| What are vocal cords attached to? | Arytenoid cartilages |
| What are the small cartilage superior to the arytenoid cartilages? | corniculate cartilages |
| What is the vocal folds and the opening between them? | Glottis |
| What is the windpipe? | Trachea |
| What are the branched airways extending throughout lungs? | Bronchial treee |
| What branch of tAnother name for the right and left bronchi? | Primary bronchi |
| What is another name for the secondary bronchi? | Lobar bronchi |
| What is another name for the tertiary bronchi? | Segmental bronchi |
| Where is the location of external respiration between alveoli and blood capillaries? | Lung |
| What is the medial indentation where main bronchus, blood vessels, and nerves enter lung? | Hilum of lung |
| What is the serous membrane on surface of lung? | Visceral pleura |
| What is the serous membrane on inside of thoracic wall and superior surface of diaphragm? | Parietal pleura |
| What is the small space between pleurae containing lubricating serous fluid? | Pleural cavity |
| What involves the movement of air from outside the body through the bronchial tree and into the alveoli and the reversal of this air movement to allow gase (oxygen and carbon dioxide) exchange between air and blood? | Pulmonary ventilation/ breathing |
| What causes the movements of pulmonary ventilation? | Changes in size of thoracic cavity that results from skeletal contractions |
| When does the size of the thoracic cavity increases? | Inspiration |
| The volumes of air that move in and out of the lungs during various phases of breathing are called? | respiratory (pulmonary) volumes and capacities |
| What instrument measures respiratory volume? | spirometer |
| What is the volume of air you breath in or out? | Tidal volume |
| What is the average tidal volume? | 500 mL |
