Module 11 ML-3 Flashcards
1
Q
What happens when there is a mucus plug in the bronchioles?
A
o2 is blowed from reaching the alveoli so one pulmonary artery constricts and diverts the blood to a different location so gas exchange can occur
2
Q
What happens when there is a blood clot in the pulmonary arteriole?
A
the bronchiole vasoconstricts so air is sent in a different healthy location in the lung
3
Q
Ventilation perfusion inequality is resposible for what?
A
the drop in po2 from alveoli to pulmonary venous blood
4
Q
what is the effect of gravity on blood in our upright posture at rest?
A
at the top of the lung their is decreased perfusionr ate so po2 is less than 105
-bottom of th lung there is increased perufsion so P02=105 so when the blood reaches the pulomonary vein it equals 100
