Osmosis video - Regulation of pulmonary blood flow

Pulmonary blood flow refers to the flow of blood through the lungs, and reflects the cardiac output of the right ventricle. Pulmonary blood flow (Q) is directly proportional to the difference in pressure between the pulmonary artery and the left atrium (the delta P); and inversely proportional to the resistance of the pulmonary vasculature (R). Q=ΔP/R
