What do the Right/Left Hepatic Ducts form?

The Common Hepatic Duct

What does the Common Hepatic Duct empty into the Cystic Duct, which empties into the Gallbladder?

Bile

What duct in the Binary System is a two-way duct (stuff goes in/out)?

Cystic Duct

Why does the Cystic Duct carry the bile to the Gallbladder?

For storage
