T/F: the pulmonary circulation is a low pressure system (around 14mmHg in
the pulmonary artery)
→ True
T/F: the pulmonary circulation is HIGH compliant; therefore it can tolerate
large increases in blood volume with little to no change in pressure
→ True
as additional volume of blood enters the lungs, why doesn't pressure
increase?
→ -capillaries that previously had little or no blood flow are
RECRUITED
-happens especially in APEX
-as a result pulmonary pressure does not increase much
-DISTENTION: blood filled capillaries are already open but they dilate even
more in order to accommodate increased blood volume
T/F: recruitment and distention occur simultaneously but recruitment usually
