The Liver.
liver & kidney
Absorbed nutrients from the intestines travel to the liver via the hepatic portal vein. This vein carries blood rich in nutrients from the intestines directly to the liver for processing and storage. Once in the liver, the nutrients are metabolized and distributed to the rest of the body as needed.
The Liver.
The enterohepatic system refers to the circulation of substances between the liver and the intestines. Bile acids are released from the liver into the intestines to aid in digestion, and are then reabsorbed in the intestines and returned to the liver. This system helps in the recycling of bile acids and certain drugs in the body.
The liver filters harmful substances from the blood and metabolizes them into less toxic compounds. The kidneys then filter these compounds out of the blood and excrete them in the urine. Additional detoxification processes can occur in the lungs, skin, and intestines before harmful substances are eliminated from the body.
Roughly 20% is absorbed through the stomach wall, depending on the contents of the stomach. The rest is absorbed in the small intestine.
hepatic portal system
The portal vein is a blood vessel that carries blood from the digestive organs to the liver. It plays a crucial role in delivering nutrients and toxins absorbed from the intestines to the liver for processing.
Absorbed nutrients from ingested food passes through the wall of the intestines into blood vessels, which take them throughout the body. The liver, the main organ involved in digestion, is responsible for breaking up, digesting and absorbing fats, and for detoxifying blood.
The liver receives the bulk of the water soluble nutrients.Little absorption occurs in the oral cavity, esophagus, and stomach. The small and large intestines are where most absorption takes place. The blood flows from the intestines back to the liver via the portal vein.
Nutrients are absorbed throughout the digestive process. Specific nutrients are absorbed in the stomach and large intestines, but the majority of nutrients are absorbed in the small intestines.
