I.Bronchial systemic venous blood drains directly into the pulmonary veins.

Question

Quizplus · Accepted Answer

Bronchial systemic venous blood drains directly into the pulmonary veins, mixing oxygen-poor blood with freshly oxygenated pulmonary venous blood on its way to the left ventricle. Bronchial blood flow is only 1% to 2% of the cardiac output, which meAnswer that the anatomical shunt from this source is usually less than 2%. This also meAnswer that left ventricular output is approximately 1% to 2% greater than right ventricular output.
