What is the path of blood the left renal artery via the hepatic portal vein heart and lungs?

The left renal artery branches off from the abdominal aorta and supplies blood to the left kidney. After filtering waste, the blood from the kidney enters the renal veins, which drain into the inferior vena cava. The inferior vena cava carries this deoxygenated blood to the heart, where it is pumped to the lungs via the pulmonary arteries for oxygenation. Once oxygenated, the blood returns to the heart and is then distributed throughout the body, including the hepatic portal vein, which directs blood from the digestive organs to the liver for processing.
