Arterial Branches Interlobular

Interlobular arterial branches (liver, rami arteriosi interlobulares hepatis) are branches of arteries that pass between the lobules of the liver. They provide blood supply to the liver and its functional activity.

The liver arteries have several types of branching: intralobular, interlobular and segmental. Intralobular arteries provide blood supply to individual liver lobules, while interlobular and segmental arteries provide a wider blood supply over the entire surface of the liver.

Interlobular branches can be either primary or secondary, depending on their size and number. They pass between the lobules and ensure a more even distribution of blood over the entire surface of the liver. This is especially important for maintaining normal liver function and preventing liver tissue damage.

In addition, the arterial branches of the liver are involved in the regulation of blood flow in the body. For example, when blood pressure increases, blood flow to the liver increases, which can lead to increased liver activity and the release of hormones such as insulin and glucagon.

In general, the arterial interlobular branches play an important role in the functioning of the liver and maintaining its health. However, with liver pathology, for example, with cirrhosis or hepatitis, the blood supply to the liver may be impaired and complications such as liver failure may occur. Therefore, to maintain liver health, it is necessary to monitor blood pressure and other factors that may affect liver function.



Arterial interlobular blood flow in the liver ensures the exchange of oxygen and nutrients between the lobes of the liver. Thanks to direct two-way capillary exchange, the liver parenchyma can effectively remove tissue metabolic products from the blood.

The arterial branch connecting two lobar arteries in the form of an arterial ligament is called the interarterial ligament. The location of the interarterial ligaments is known as interlobar anatomy.

Interlobular circulation Interlobular anatomy is provided by interwoven collagen and muscle fibers that converge radially, forming a finger-shaped or triangular space in the section. Along the interarterial canal there are numerous small veins called interangial veins. The arteries draining into the interurteral ligament provide direct vascular communication between the two lobules and are called interlobar arteries. The interconnected lobe or lobes of the liver deliver blood to different parts of the hepatic artery, a tributary between the lobes of the liver. Some veins receive blood from the interlobular region
