Janssen-Respiratory
Mrs. Janssen's Respiratory System Test
| Question | Answer |
|---|---|
| What are the tiny clusters of sacs that allow for gas exchange in the lungs? | alveoli |
| What is the intermediate form of carbonic acid? | bicarbonate ion |
| What is inflammation of the bronchi called? | bronchitis |
| What are the first passageways by which the air passes through the nose or mouth to the air sacs of the lungs in which branches no longer contain cartilage or glands in their submucosa? | bronchioles |
| What condition is characterized by overdistension of the pulmonary alveoli and fibrosis of lung tissue? | emphysema |
| What is another word for exhalation? | expiration |
| What is gas exchange between the lungs and blood called? | External respiration |
| What is another word for inhalation? | inspiration |
| What is gas exchange between blood and body cells called? | Internal respiration |
| What material is the larynx made of? | cartilage |
| Where does oxygen bind to travel through the blood? | hemoglobin |
| What is the muscular tube that extends from the posterior nasal cavity to the esophagus called? | pharynx |
| What is the serous membrane that covers the lungs and lines the thoracic cavity? | pleura |
| What are the main airway passages that branch off the trachea called? | bronchi |
| What is another term for breathing (inspiration and expiration)? | ventilation |
| What is the chemical substance that coats the alveolar walls and reduces surface tension? | surfactant |
| What is the most basic function of respiration? | gas exchange |
| What are the rings of the trachea made of? | cartilage |
| Which type of cells beat back & forth and push mucous up & out of the trachea? | cilia |
| Which type of cells produce mucus that traps inhaled particles and pathogens? | goblet cells |
| Which primary bronchus is the more likely site for an object to be inhaled? | right bronchus |
| Which tissue allows for expansion and contraction of the lungs during ventilation? | elastic |
| The sinuses and auditory tubes drain into the nasal cavities and the ____________. | nasopharynx |
| Where does gas exchange take place in the lungs? | alveoli |
| What is the normal volume of air that is inhaled or exhaled during a single, quiet breath? | tidal volume |
| What is the additional amount of air that can be expired from the lungs by determined effort after normal expiration? | Expiratory reserve volume |
| What is the maximum amount of air a person can expel from the lungs after a maximum inhalation? | vital capacity |
| The diaphragm _____________during inspiration. | lowers |
| The diaphragm _____________during exspiration | rises |
| Where is hemoglobin located? | Red blood cells |
| Where is the majority of CO2 transported in the blood? | plasma |
| What determines which direction O2 & CO2 diffuse? | Concentration gradient |
| What 2 areas of the brain are involved in the nervous control of breathing? | medulla & pons |
| What is the most important chemical factor that modifies respiratory rate and depth? | CO2 levels |
| An increased depth and rate of breathing greater than the body demands is___________. | hyperventilation |
| During hyperventilation, is more CO2 retained or expelled? | expelled |
| Deep inspiration that ventilates all alveoli. | yawn |
| Happy response of inspiration followed by release of air in several short breaths. | laugh |
| Sad response of inspiration followed by release of air in several short breaths | crying |
| Diaphragm spasms that produce sound when air hits the vocal folds of closed glottis | hiccup |
| Mechanism that clears lower respiratory passages, forces air out through mouth | cough |
| Mechanism that clears upper respiratory passages, forces air out through nasal cavities | sneeze |
