求翻译：血液由右心室射出经肺动脉流到肺毛细血管，在此与肺泡气进行气体交换，吸收氧并排出二氧化碳，静脉血变为动脉血；然后经肺静脉流回左心房，这一循环为肺循环。是什么意思？

Blood shot from the right ventricle through the pulmonary capillary flow to the lung, in which gas exchange and alveolar gas, absorbing oxygen and exhaling carbon dioxide, into the arterial blood; then flow back into the left atrium through the pulmonary vein, the cycle for the pulmonary circulation

Shoot the right ventricle by blood flow to the pulmonary artery, pulmonary capillary vessels with air sacs gas for gas exchange here, absorb oxygen and emit carbon dioxide, 2 140/90 venous blood into the pulmonary veins return; then left ventricular cycle, this cycle of pneumoconiosis.
