|
What is V? Q?
|
ventilaion and perfusion
|
|
|
How doe spulmonarhy blood flow supply the lungs?
|
it doesn't supply them, it feeds blood in to be oxygenated
|
|
|
what is the division called that supplies the lungs with blood?
|
bronchial perfusion
|
|
|
Which of the following does NOT contain lymphatics?
Arery vein arlveolar walls airway |
alveolar walls
|
|
|
What is the edema safety factor? what part of the lungs provides this?
|
up to 20 mmHg of safety net for edema pressure, achieved by lymphatics
|
|
|
Which wall are more compliant:
pul artery or aorta pul vein or systemic vein |
pul artery
equal |
|
|
Where do ronchial veins send de-Oxygenated blood?
|
Left atrium
|
|
|
Where is there "mixed venous" blood? what causes this?
|
pulmonary veins - get de-o2 blood from bronchial veins, and o2 blood from the lungs
|
|
|
match these blood volumes (83%, 7%, 10%) with their locations (pulmonary, heart, systemic)
|
systemic - 83
pulmonary - 10 heart - 7 |
|
|
What are extra alveolar vessels? What type of pressure do they comrpsie?
|
pul art/vein - intrapleural pressure
|
|
|
what are the intraalveolar vessels? what type of pressure surrounds them?
|
pul capillaries, alveolar pressure
|
|
|
What are the 2 ways capillary collapse can happen? (increases/decreases in pressure?
|
increase in alveolar pressure
or decreased capillary pressure |
|
|
How do you get increased alveolar pressure (that could cause collapse)
|
forece expiration, PEEP
|
|
|
how do you get decreased capillary pressure, that could cause collapse?
|
hypovolemia
|
|
|
What are the 3 zones of the lung, and how much flow is in each?
|
1 - apex - zero
2 - apex/middle - intermittent (during systole) 3 - base - continuous flow |
