In cytokine storm, what are three things that happen to reduce gas exchange? I swelling increases distance between alveoli & circulatory system I oxygen builds up in the alveoli red blood cells invade the alveoli carbon dioxide builds up in the alveoli fluid fills up alveoli scar tissue forms making lungs more flexible hyaline membrane forms making lungs less flexible

Of the following, which does not explain why the partial pressure of oxygen is lower in the lung than in the external air? Air in the lung is humidified; therefore, water vapor pressure alters the pressure Carbon dioxide mixes with oxygen Oxygen is moved into the blood and is headed to the tissues Lungs exert a pressure on the air to reduce the oxygen pressure.
Figure 39.7 Which of the following statements about the mammalian respiratory system is false? When we breathe in, air travels from the pharynx to the trachea. The bronchioles branch into bronchi. Alveolar ducts connect to alveolar sacs. Gas exchange between the lung and blood takes place in the alveolus.
A partial pressure gradient of oxygen exists between ________. a. air and lungs b. lungs and metabolically active tissues c. air at sea level and air at high altitudes d. all of the above
Which of the following are structural features of the trachea? C-shaped cartilage smooth muscle fibers cilia all of the above
Due to its partial pressure gradient, carbon dioxide diffuses from cells into tissue fluid and into the ________; in the lungs, carbon dioxide diffuses into the ________. a. alveoli; bronchioles b. bloodstream; bronchioles c. alveoli; bloodstream d. bloodstream; alveoli
Fig. 2.1 shows photomicrographs of lung tissue at the same magnification. One shows healthylung tissue and the other shows lung tissue from a person with COPD. Line AB shows the diameter of one healthy alveolus. Line CD shows the diameter of an area oflung where the alveoli have been destroyed. The real diameter of healthy alveolus is 200 µm.If line AB in the picture is 2 cm, calculate the magnification of the picture...... Magnification: …………………… please solve with step max 15-20 minutes and no reject thank u
All cilia of the upper respiratory tract move mucus to the: trachea O esophagus vestibule of the nose The last complete ring of cartilage in the respiratory tract as you move from the nose toward the lungs is in the: trachea bronchi O larynx O bronchioles
Pneumonia interferes with CO2 elimination and O₂ uptake primarily by: Slowing diffusion by reducing the surface area of alveoli Reducing air flow into and out of the lungs by reducing the cross sectional area of the airways Decreasing the partial pressure of the air in the alveoli. O loss of elasticity of the lungs making it difficult to move air into and out of the lungs O increasing the diffusion distance due to buildup of fluid within the alveoli Which of the following is not part of the respiratory membrane? all of the other answers are part of the respiratory membrane the squamous cells of the alveoli areolar connective tissue a basement membrane the endothelium of the capillary
What are the smallest conducting-zone bronchioles called? alveolar ducts alveoli respiratory bronchioles terminal bronchioles
