Quizplus · Accepted Answer

The catheter inserted into the left subclavian vein travels through the venous system into the right atrium, passes through the tricuspid valve into the right ventricle, and then through the pulmonic valve into the pulmonary artery system to reach the pulmonary capillaries. It does not pass through the pulmonary veins, which carry oxygenated blood from the lungs back to the left atrium of the heart.
