Ductus Venosus

The ductus venosus is a tubular structure of the liver that connects it to the hepatic vein system. It plays an important role in regulating blood flow and metabolism within the liver, and also ensures the removal of excess metabolites from the liver.

The ductus venosus begins in the sinusoidal capillaries of the liver and passes through the liver, where it becomes larger and wider. It then leaves the body of the liver and enters the hepatic veins, connecting with the right and left hepatic veins. This allows the exchange of substances between the blood in the liver and the general blood of the body.

The main function of the ductus venosus is to maintain a constant exchange of substances between the hepatic blood and the general bloodstream, which is an important task for liver health. Venous flow moves along the venous vessel and accounts for the bulk of the blood passing through the liver in one minute. The volume of venous flow can vary depending on the activity of the liver, regulating the body's metabolic rate.

It is important to note that the blood passing through the liver capillaries contains many toxins such as alcohol, drugs and other substances that the liver must detoxify before continuing on its way to the lungs. Therefore, the venous ducts act as cleansing and filtering devices, helping to protect the general bloodstream from the harmful effects of toxins.

Many people have problems with the venous lumen, which can manifest themselves in the form of various diseases.
