Gallbladder01:17

Gallbladder

The gallbladder is a small, pear-shaped organ that plays a crucial role in our digestive system. Measuring about 10 cm in length, it is comparable in size to a kiwi fruit and is located in a hollow area on the lower surface of the liver. The gallbladder's primary function is to store and concentrate bile, a fluid produced by the liver that aids in digestion.
The gallbladder's anatomy consists of three regions: the fundus, body, and neck. Extending from the neck, the cystic duct joins the common...
Bile01:19

Bile

Bile is a crucial bodily fluid, characterized by its yellow-green color and alkaline nature. Produced in the liver, it is transported through the common hepatic duct into either the cystic duct, leading to the gallbladder, or directly into the common bile duct. The flow of bile is regulated by the sphincter of Oddi located at the entrance of the duodenum. When this sphincter is closed, bile is redirected to the gallbladder for storage and concentration.
Bile is released when dietary fats enter...
Gross Anatomy of the Liver01:17

Gross Anatomy of the Liver

The liver, the largest gland within the human body, is a firm and reddish-brown organ. This wedge-shaped structure weighs approximately 1.5 kg and occupies a significant portion of the right hypochondriac and epigastric regions. It extends more to the right of the body's midline than to the left.
Located under the diaphragm, the liver is almost entirely ensconced within the rib cage, providing it with substantial protection. Except for the superior most bare area, the liver's surface is covered...
Liver Histology01:27

Liver Histology

The microscopic anatomy of the liver is a complex and intricate system that comprises numerous structural units known as liver lobules, each of which is comparable in size to a sesame seed. These hexagonal structures consist of plates of liver cells or hepatocytes, which are characterized by their versatility and abundance of cellular apparatus like rough and smooth ER, Golgi apparatus, peroxisomes, and mitochondria.
Hepatocytes perform a variety of essential functions. They secrete...
Development of the Lymphatic System01:15

Development of the Lymphatic System

The development of lymphatic tissues and vessels in embryonic life begins around the fifth week. These structures originate from the mesoderm layer, with lymph sacs emerging from developing veins.
The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...

Area of Science:

  • Medical Imaging
  • Anatomy
  • Surgical Planning

Background:

  • The biliary tree exhibits significant anatomical variability.
  • This complexity presents challenges in diagnosing and treating biliary pathologies.
  • Understanding biliary anatomy is crucial for liver surgery.

Purpose of the Study:

  • To review the embryology and anatomy of the biliary system.
  • To identify and report common anatomical variations of the intrahepatic and extrahepatic biliary systems.
  • To provide a reference for clinicians and surgeons.

Main Methods:

  • Analysis of 3D CT reconstructions.
  • Utilized CT images from 178 healthy potential living liver donors.
  • Focused on intrahepatic and extrahepatic biliary tree anatomy.

Main Results:

  • Detailed common anatomical patterns of the intrahepatic biliary system.
  • Documented frequent variations in the extrahepatic biliary system.
  • Established a baseline understanding of normal biliary anatomy.

Conclusions:

  • Variations in biliary anatomy are common and must be recognized.
  • Accurate anatomical knowledge aids in diagnosing biliary diseases.
  • This study provides valuable anatomical data for liver transplantation and surgery.
