Pulmonary Blood Flow Flashcards
surface area of gas exchange
-50-100m2
pathway the pulmonary circulation
right atrium-tricuspid valve-right vetricle-pulmonary valve-pulmonary artery-lung-pulmonary vein-left atrium
function of pulmonary circulation
-carry blood from left to right
-arterization of the venous blood
-filtration of any embolism
-blood reservoir
-fluid clearance in alveoli
-ACE
character of pulmonary vessel
-thin
-high compliance
from character of pulmonary vessel, what capability does it has
-low resistant
-low pressure
-high capacitance
