From the Femoral vein, you would go to the inferior vena cava, which then leads to the right atrium of the heart. From there, you'd go to the right AV valve to the right ventricle and then to the pulmonary SL valve. Then, you'd go to the pulmonary artery and then the lungs. Once in the lungs, go to the lower lobe of the right lung. There are three lobes in the right lung, unlike the left lung, which has two. The three lobes are the Superior lobe, at the top, the Middle lobe, in the middle, and lastly, the Inferior lobe at the bottom.

The right femoral artery is in the right upper leg. It branches off from the lower part of  the main  abdominal artery. It doesn't directly feed into the lower left lung.
