The portal venous, hepatic arterial and biliary systems run to- gether within the intrasegmental parts of the hepatic parenchyma, but the main hepatic veins course in the interlobar or intersegmental fissures of the liver.
intrasegmental. vessels that travel WITHIN segments and lobes. INTERsegmental. hepatic veins are inter or intrasegmental.
(a) Main lobar fissure: Runs obliquely between the neck of the gallbladder and right portal vein. Contains the middle hepatic vein and separates the right and left hepatic lobes. Its course is short and variable.
right hepatic vein located in the right intersegmental fissure divides the right lobe into right lateral (posterior) and right medial (anterior) sections.
Definition of intersegmental : occurring between or involving two or more segments intersegmental spinal ligaments specifically : lying between somites intersegmental nerves.
The ligamentum venosum, also known as Arantius' ligament, is the fibrous remnant of the ductus venosus of the fetal circulation. Usually, it is attached to the left branch of the portal vein within the porta hepatis. It may be continuous with the round ligament of liver.
The major branches of the portal veins run centrally within the segments (intrasegmental) with the exception of the ascending portion of the left portal vein, which runs in the left intersegmental fissure.
The portal vein is a blood vessel that delivers blood to the liver from the stomach, intestines, spleen, and pancreas. Most of the liver's blood supply is delivered by the portal vein.
Hepatic artery (HA) is soft oxygenated blood vessel that supplies oxygen-rich blood to the liver, duodenum, and pancreas.
The right portal vein divides into anterior (supplying segments 5 and 8) and posterior (supplying segments 6 and 7) branches. The left portal vein may be divided into transverse and umbilical portions, as delineated by the ligamentum venosum, and is mostly extrahepatic in its course.
Ligamentum teres (or round ligament) of the liver is a cord-like ligament found within the falciform ligament on the inner surface of the anterior abdominal wall and represents a remnant of the umbilical vein, which is a connecting venous structure between the placenta and the umbilical portion of the left portal vein.
Hepatic veins are blood vessels that return low-oxygen blood from your liver back to the heart. The veins are key players in the supply chain that moves the blood that delivers nutrients and oxygen to every cell in your body.

[7] The hepatoduodenal ligament has lymphatic pathways, which will flow into the Pecquet cistern at a sub-diaphragmatic level. It also has the name "pars tensa" of the small omentum; its thickness contains the portal triad, that is, the portal vein, the hepatic artery, and the common bile duct.
The falciform ligament is a ligament that attaches the liver to the front body wall, and separates the left lobe of the liver into the left medial lobe and left lateral lobe.
Around 90% of world trade*, including raw materials, food, computers, clothes and everything in-between, is carried out by the international shipping industry. Shipping is the lifeline of the global economy.
A yacht is a floating piece of art. Pleasure crafts come in a wide variety of sizes, with some being large enough to have their own helicopter platforms, pools, saunas, bars and gyms. They are the embodiment of luxury, with every space and facility designed to perfectly suit their owners’ needs.
These workhorse vessels are responsible for reclaiming land, maintaining waterways and preparing infrastructure construction. They are robust and designed for work such as heavy-duty pumping and drilling through layers of sand in harsh conditions.
There is a broad range of military vessels and fields in which they operate. This includes operations against terrorism, piracy, smuggling, drug trafficking and illegal immigration, not to mention the distant but real prospect of war.
These boats, ranging from crab catchers to fishing trawlers, go out to sea in search of fish in the harshest conditions. The trawlers themselves are floating factories, which catch, produce, pack and freeze the fish onboard.
