| Question | Answer |
|---|---|
| The major role of the respiratory system is to? | Supply the body with oxygen and dispose of carbon dioxide |
| Circle True or False. Four processes - pulmonary ventilation, external respiration, transport of respiratory gases, and internal respiration must all occure in order for the respiratory system to function fully. | True |
| The upper respiratory structures include the nose, the larynx and the _________? | Pharynx |
| Circle the Correct term. The thyroid cartilage/oropharynx is the larges and most prominent of the laryngeal cartilages. | Thyroid cartilage |
| Circle True or False. The epiglottis forms a lid over the larynx when we swallow food: it closes off the respiratory passageway to incoming food or drink. | True |
| Air flows from the larynx to the trachea, and then enters the? | Left and right main bronchi |
| Circle the correct term. The lining of the trachea is pseudostratified ciliaed columnar epithelium/transitional epithelium, which propels dust particles, bacteria, and other debris away from the lungs. | Columnar epithelium |
| Circle true or false. All but the most minute brances of the respiratory tree have cartilaginous reinforcements in their walls. | True |
| ________, tiny balloonlike expansions of the alveolar sacs are composed of a single thin layer of squamous epithelium. They are the main strucctural and functional units of the lung and the actual sites of gas exchange. | Alveoli |
| Circle the correct term. Fissures divide the lungs into lobes, three on the right and two/three on the left? | Two |
| Chapter 37A Lab. Circle the correct term. Inspiration/expiration is the phase of pulmonary ventilation when air passses out of the lungs. | Expiration |
| Which of the following processes does not occur during inspiration/ | gas prssure inside the lungs is lowered |
| Circle true or False. Vesicular breathing sounds are produced by air rushing through the trachea and bronchi. | True |
| During normal quiet breathing, about _______ ml of air moves into and out of the lungs with each breath. | 500 |
| Circle the correct term. Tidal volume/vital capacity is the maximum amount of air that can be exhaled after a maximal inspiration? | Tidal volume |
| Circle true or false. The neural centers that control respiratory rhythm and maintain a rae of 12-18 respirations per minute are located in the medulla and thalamus? | medulla |
| Circle the correct term. Changes in ph and oxygen concdentrations in the blood are monitored by chemoreceptor regions in the medulla/aortic and carotid bodies? | Carotid bodies |
| The carbonic acid-bicarbonate buffer system stabilizes arterial blood ph at: | 7.4 + or - 0.02 |
| Circle the ocrrect term. Acids/Bases released into the blood by the body cells tend to lower the ph of the blood and cause it to become acidic. | Acids |
| Circle true or false. Rate and depth of breatin, hyperventilation, and hypovetilation should have little or no effect on the acid-base balance of blood. | False. |
