Bile Ducts Are Tubular Structures That Carry Bile, A Digestive Fluid Produced By The Liver, Away From The Liver And Into The Small Intestine. Bile Is Essential For The Digestion And Absorption Of Fats And Fat-Soluble Vitamins. Bile Ducts Are Also Referred To As Biliary Ducts Or Ducts Of The Biliary Tree. The Bile Ducts Consist Of A Network Of Hepatic Ducts, Cystic Ducts, And Common Bile Ducts. The Hepatic Ducts Are Formed By The Union Of The Left And Right Hepatic Ducts And Carry Bile Produced By The Liver. The Cystic Duct Is A Short, Curved Tube That Connects The Gallbladder To The Common Bile Duct And Transports Bile From The Gallbladder To The Biliary Tree. The Common Bile Duct Is A Longer Tube That Carries Bile From The Hepatic Ducts, Cystic Duct, And Gallbladder And Empties It Into The Duodenum, The First Part Of The Small Intestine. Bile Ducts Are Lined With A Thin Layer Of Cells Called Epithelial Cells. These Cells Secrete Mucus And Other Substances That Help To Protect And Lubricate The Bile Ducts. The Walls Of The Bile Ducts Are Made Up Of Layers Of Muscle And Connective Tissue, Which Work Together To Contract And Relax In Order To Move Bile Through The Ducts. The Bile Ducts Are A Vital Part Of The Digestive System And Play An Important Role In The Digestion And Absorption Of Fats And Fat-Soluble Vitamins. Without Bile Ducts, Food Would Not Be Properly Broken Down And Nutrients Would Not Be Properly Absorbed. Therefore, Keeping The Bile Ducts Healthy Is Essential For Optimal Digestion And Nutrient Absorption.
