Total peripheral resistance refers the cumulative resistance of the thousands of arterioles in the body, or the lungs, respectively. See Arteriole.
The total peripheral resistance of healthy lung arterioles is typically about 0.15 to 0.20 that of the body, so pulmonary artery mean blood pressure s are typically about 0.15 to 0.20 of aortic mean blood pressures.
