The path blood take from the right femoral vein to lower lobe of the right lung via the pulmonary artery is as follows; we start in the right femoral vein which is located in the thigh and travel to the right external iliac vein. Blood from the femoral vein emptiness in the inferior vena cava but first must travel through the external iliac. The iliac vein joins with the inferior vena cava. The inferior vena cava takes deoxygenated blood form the lower limbs of the body to the right atrium (Thibodeau
