At the range of 10−15 m (1 femtometer), the strong force is approximately 137 times as strong as electromagnetism, a million times as strong as the weak interaction, and 1038 times as strong as gravitation.
The common hepatic duct is formed by the union of the right and left hepatic ducts emerging out from the right lobe of the liver.
The right hepatic duct is responsible for draining bile from the right half of the body whereas the left hepatic duct drains it from the left side of the body.
At the junction of the right and left hepatic duct, the common hepatic duct gets formed which then joins the cystic duct and then the common bile duct is formed.
