Extra Hepatic Biliary Apparatus (Part 1) - Introduction, Right, Left, & Common Hepatic ducts

Extra-Hepatic Biliary Apparatus (EHBA) – Part 1 | Introduction & Hepatic Ducts | Anatomy for BAMS
In this video, Part 1 of the Extra-Hepatic Biliary Apparatus (EHBA) series, we cover the fundamental concepts and initial components of the biliary system in a clear, structured, and exam-oriented manner. This lecture begins with an introduction to the extra-hepatic biliary apparatus, its definition, importance, and anatomical overview, forming a strong foundation for understanding subsequent topics.
The video then explains in detail the right and left hepatic ducts, including their formation, course, relations, and significance in bile drainage from the liver. Special attention is given to the common hepatic duct, its formation, length, course, and relations, which is clinically important in cases of obstructive jaundice and hepatobiliary surgeries. The accessory hepatic duct, an important anatomical variation, is also discussed with its origin, drainage pattern, and surgical relevance, highlighting why knowledge of variations is crucial during procedures like cholecystectomy.

This lecture is designed to help students understand: • Introduction and overview of EHBA
Right and left hepatic ducts – formation and course
Common hepatic duct – anatomy and relations
Accessory hepatic duct – variations and clinical importance
Applied anatomy and exam-relevant points

This video is especially useful for BAMS students, medical anatomy learners, and anyone preparing for university exams and viva, as the concepts are explained in a systematic and easy-to-remember format.
