Ch. 10 – Flashcards

Which of the following is not part of the lower respiratory tract? bronchi lungs alveoli trachea larynx

Which of the following is not a part of inspiration? The pressure in the lungs increases. The rib cage moves up and out. The intercostal muscles pull the ribs outward. The diaphragm contracts and moves down. Air rushes into the lungs

Ventilation includes inspiration only. expiration only. both inspiration and expiration the volume of air that can be exhaled. the transportation of oxygen to the cells in the body

Which of the following is not part of the upper respiratory tract? bronchi nasal cavity epiglottis pharynx glottis

Which of the following is not a symptom of emphysema? The elastic recoil of the lungs is reduced. The surface area for gas exchange is reduced. The alveoli are distended and their walls damaged. The airways are inflamed and filled with mucus. The heart works harder to force more blood through the lungs

Which of the following is not part of the respiratory system? trachea pharynx esophagus bronchus nasal cavity

Which structure is the initial entry way for air to enter the respiratory system? nose trachea lungs pharynx esophagus

The amount of air that moves in and out with each breath is called the vital capacity. tidal volume. inspiratory reserve volume. expiratory reserve volume. residual volume

If it were not for the nasal cavity, we would not be able to speak. more debris would enter the lungs. oxygen would not be exchanged in the alveoli. food would go down the wrong pipe. air would not be conducted to the lungs

Why is the actual flow of air into the alveoli during inspiration passive? because there is a continuous column of air from the pharynx to the alveoli because the lungs are surrounded by the thoracic wall because the alveoli have a very large surface area because the intercostal muscles are involved because the diaphragm is involved

If you force inspiration, how much more air can you breathe in than the tidal volume? two times three times four times five times six times

Carotid bodies and aortic bodies detect blood pH. oxygen blood levels. oxygen tissue levels. stretching of the lungs. the residual volume

Which of the following infections does not affect a structure in the respiratory tract? laryngitis strep throat tonsilitis otitis media bronchitis

Which reaction does carbonic anhydrase catalyze? H+ + HCO3- → H2CO3 H2CO3 → H2O + CO2 Hb + O2 → HbO2 HbO2 → Hb + O2 None of these.

How does breathing at a very low rate affect the reaction H+ + HCO3- → H2CO3 → H2O + CO2 ? pushes it to the right pushes it to the left does not affect it increases the rate at which it occurs decreases the rate at which it occurs

What is the correct order of the following steps in the progression of lung cancer in a smoker? 1. Cilia are lost. 2. There is a thickening and callusing of the cells lining the bronchi. 3. Metastasis occurs. 4. A tumor forms. 5. Cells with atypical nuclei appear. 1,2,3,4,5 2,1,5,4,3 5,1,2,3,4 1,2,4,3,5 2,1,4,5,3

What do inspiration and expiration have in common? They both use the same pathways. The air travels in the same direction in both. They both end in the lungs. They both conduct air from the outside. They both remove wastes from the tissues

Which of these lower respiratory diseases should be treated with antibiotics? pulmonary fibrosis pulmonary tuberculosis emphysema asthma lung cancer

Which respiratory structure is used to produce sound? larynx nose pharynx glottis esophagus

Which volume can add an additional 2,900 ml of air to the lungs? inspiratory reserve volume expiratory reserve volume residual volume vital capacity tidal volume
