The collage takes us from the proton (top left) through to element and molecule and finally to strands of DNA in the first row. The second row starts with a group of cells advances to the tissues, to the organ which in this case is the liver.
The third row represents units2unity from the organ (liver with its connections (arteries and veins to body systems and the body.
The fourth row advances from the body to the person, couple family home community.
The last row is the village advancing to the city, state, country, earth and solar system.
Note the similarity between the proton and the earth, and between the atom and the solar system.

This has and will always be true – from the dawn of man through ancient times when the liver was used by the Etruscans as a divine agent to predict the future – (hepatomancy – middle image) – to modern times of liver transplantation

The sinusoids and hepatic cords combine to form a liver lobule which is a functional and structural unit of the liver. At the center of the lobule is the central vein from which emanate many cords of liver tissue. At the periphery of the lobule there are 4-5 groups of portal triads consisting of distal branches of the portal vein (dark blue), hepatic artery (red) and biliary radicle (green). They create the border of the lobule.

In the 4th week of gestation, the primitive endoderm gives rise to a foregut diverticulum called the hepatic diveticulum at the junction of the of the foregut and midgut. The hepatic diverticulum is the precursor for the liver bile ducts and gallbladder. hepatic diverticulum pars hepatica and pars cystica.

The artistic rendering shows the celiac axis (red) giving rise to the splenic artery and the hepatic artery.
The portal vein (blue) is derived from the splenic vein and superior mesenteric vein, and drains into the liver.
The biliary system (green) consists of the intrahepatic ducts, that drain into the common hepatic duct that lies in the porta hepatis. Once the CHD receives the cystic duct from the gallbladder it becomes the common bile duct.

The cirrhotic liver has a small right lobe and a large left lobe as a compensation for reduced size and function of the right lobe. This gives the left lobe a snout like shape in contrast to the small triangular right lobe. This liver thus takes on a shark head like appearance and the structures (arteries vein nerves and ligaments entering the porta of the liver look like shark feed.
