Abdomen 04: Liver, Gallbladder, and Pancreas Flashcards
How does the liver develop?
The liver bud develops from hepatic diverticulum of the foregut and grows into venous network of fitelline vein
In liver development, what do the capillaries become?
Sinusoids
In liver development, what does the liver bud make?
Hepatocytes
Gallbladder
An organ that stores bile for release; it is found in the midclavicular line with the edge of the rib cage just beneath the right lobe of the liver
Falciform ligament
The ligament that runs ventrally between the two lobes of the liver
Bare area of the liver
An area of the superior side of the liver where there is no ligament or peritoneum present
Subphrenic recess
A recess between the liver and the diaphragm
Hepatorenal recess
A recess between the liver and the kidney
Portal triad
The entrance to the liver
What are the components of the portal triad?
The proper hepatic artery, the portal vein, and the bile duct
Caudate lobe
A small lobe of the liver that is inferior to the portal triad
Quadrate lobe
A small lobe of the liver that is superior to the portal triad
What are some of the functions of the liver?
Produces bile; metabolizes carbs, fats, and proteins; filters blood from intestines; detoxification
What nerves innervate the liver?
Anterior vagal trunk and sympathetic and sensory afferents of the celiac plexus (T7-T9)
What arteries supply the liver?
Portal hepatic vein and proper hepatic artery
The portal hepatic vein drains blood from the intestines and is filtered in the liver. The liver gets about 50% of its oxygen from the portal hepatic vein
Caval system
A venous system that drains directly into the inferior vena cava without going through the liver
Portal system
A venous system that drains to the liver to be filtered, and then drained into the inferior vena cava
Portal tract
A portal vein, portal artery, and bile duct all moving together through the liver
Bile canalucili
Specialized sections of tight junctions that collect bile from the liver
Disse’s space
A specialized space outside of the sinusoid
Hepatic stellate cells
Cells found in disse’s space that store vitamin and are involved in liver injury response
