Explain how changes in the alveolar structure cause a decrease in the blood oxygen levels in emphysema?
Decrease in alveolar surface area results in less boundary across which oxygen can be absorbed into the blood.
Where do blood cells pick up oxygen?
In the lungs, in the alveolar capillaries
What is the direction of movement of gas between the blood and the alveolar duct?
i dint knoew the answer
Explain how the changes in alveolar structure cause a decrease in blood oxygen levels in emphysema?
Pneumonia fills the lung's alveoli with fluid, keeping oxygen from reaching the bloodstream.
Do the alveolar ducts absorb carbon dioxide?
No they absorb large amounts of oxygen into the blood.
What is the mechanism that allows oxygen to move from the alveolar into the pulmonary capillary blood?
Simple diffusion
If a person had too much blood passing throuh the alveolar capilaries and not enough alveolar gas to provide oxygen to the blood what would you observe?
Systemic hypoxia -- the overall insufficiency to accumulate enough oxygen (and nitrogen too, but that's inert).
What does the Heart do to the Oxygen Blood in the Pulmonary Alveolar?
it changes oxygen to Carbon dioxide in the cells and the carbon becomes carboxy heamoglobin
How is PAP determined?
A chest x ray may show alveolar disease. An arterial blood gas reveals low oxygen levels in the blood. Bronchoscopy with transtracheal biopsy shows alveolar proteinosis.
Do the lungs bring oxygen into blood?
When air reaches lungs which has thousands small sacks called alveoli the oxygen is difussed to blood capillaries that line alveolar wall.
What organ does the oxygen-carbon Dioxide take place?
Oxygen is brought into the blood, and carbon dioxide released from the blood, at the alveoli of the lungs. Gases diffuse across the alveolar membrane to enter or leave the blood.
How do alveolar and capillaries work together to provide the muscles with oxygen?
as it moves through blood vessels capillaries in the alveoli walls, your blood takes oxygen from the alveoli and gives off carbon dioxide to the alveoli
