How does nutritience move through the body?

Food contains Proteins, Fats, carbohydrates, Vitamins and Minerals. Food is broken into amine acids, Fatty acids, glycerol, Glucose, Fructose and Lactose. They are absorbed, via portal vein, into Liver. There, they are processed. It then passes via Hepatic vein into Inferior vena cave. From there, it enters into right atrium. Then right ventricle. Then through pulmonary circulation it enters, the left side of heart. from there it circulates in the syatemic circulation. It enters the interstitial space via proximal end of the cappilaries. There it is available to cells. From there waste products of metabolism are liberated into interstitial space. This fluid enters the circulation at distal end of the cappillaries.
