In forming the lung-blood barrier, all of the following are involved EXCEPT: the basal lamina O Type I alveolar cells capillary endothelial cells O Type Il alveolar cells

How does carbon dioxide exit the bloodstream at its final destination? Why does it move in the direction that it does across the alveolar surface?   When you feel a pulse, you’re feeling your radial artery expand.  What is causing your artery to expand like this?  The veins in your arms and legs have one way valves.  Explain why these valves are necessary for returning venous blood to the heart.

The functional unit of the lung, where gas exchange occurs, is the

Scenario: A patient arrives in the emergency room after struggling to breathe and is subsequently diagnosed with asthma. In this disease state the patient's airways can significantly decrease in radius. They noted that they were exercising when the episode occurred. Question stem: Based on your knowledge of lung anatomy, which of the following regions contains smooth muscle that could contract and decrease airway radius? Answers A - D A Bronchioles В The Alveoli The pleura D Type I cells

Work in a mine is known to cause inhalation of large amounts of coal dust. Inhaled coal dust can be detected in the following pulmonary cells: Capillary endothelial cells Alveolar Macrophages Respiratory epithelial cells Secretory epithelial cells O Pericapillary cells

If there is increased hydrostatic pressure on the venous side of the capillaries leading to an increase in fluid moving into the tissues why would it cause ankle edema?  What role does the lung play in development of that increased hydrostatic pressure in terms of alveolocapillary membrane/lung changes.  What is the effect on oxygen diffusion from the alveolus, on pulmonary artery pressure and resultant changes to the right side of the heart)?
