pulmonary circulation's cardiac output
equal to the CO of systemic circulation (4-6 L/min)
whats the primary reason pulmonary circulation's MAP is lower than systemics?
pulmonary vessels have a larger radius
supply vessels during lung expansion
supply vessels (pulmonary arteries and arterioles) dilate which allows for blood to flow
easier BUT capillaries compress which decreases the blood flow
3 ways blood flow through systemic circulation is controlled?
local control, hormones, SNS
CO2 in systemic circulation
causes dilation
CO2 in pulmonary circulation
causes constriction
