Abdomen - Lecture 3 Flashcards
(87 cards)
Accessory Organs to Digestion
- Liver
- Gall Bladder
- Pancreas
- Spleen
Where is the liver located?
Mostly in the right hypochondrium and a little in the epigastric region
What are the surfaces of the Liver?
- Diaphragmatic Surface
2. Visceral Surface
Diaphragmatic Surface of the Liver
- Part of Liver in contact with the Diaphragm
- Anterior, Posterior, & some Superior
- 3/4 of the liver
What are the Recesses (Potential Spaces) associated with the Liver?
- Subphrenic Recess
- Hepatorenal Recess
THEY ARE CONTINUOUS WITH EACH OTHER
Subphrenic Recess
- Separates the Liver from the Diaphragm
2. Divided into Right and Left by the Falciform Ligament
Hepatorenal Recess
Potential space between the Liver and the Right Kidney/Right Adrenal Gland
Visceral Surface of the Liver
- Inferior Portion
- Covered in Visceral Peritoneum (aside from Fossa of Gall Bladder)
- Location of the Porta Hepatis
What is the Porta Hepatis of the Liver and where is it located?
- On the Visceral Surface of the Liver (inferior side)
- Point of ENTRY for the hepatic artery and portal vein
- EXIT for the Bile Duct
What is the Portal Triad of the Liver and where is it located?
- Hepatic Artery ENTERS
- Portal Vein ENTERS
- Bile Duct EXITS
All of this happens at the PORTA HEPATIS
Lobes of the Liver
- Right Lobe
- Left Lobe
- Caudate Lobe
- Quadrate Lobe
Ligamentum Teres
Piece of the Falciform Ligament that just sort of hangs off
Falciform Ligament and Ligamentum Teres are remnants of…
Umbilical Vein
What lobes of the Liver CANNOT be seen anteriorly (Diaphragmatic Surface)?
- Caudate Lobe
2. Quadrate Lobe
Right Lobe of the Liver
- Largest Lobe
- Separated from Left Lobe by Falciform Ligament
- Gives rise to Caudate Lobe
Left Lobe of the Liver
- Separated from the Left Lobe via Falciform Ligament
2. Functionally related to/gives rise to Quadrate Lobe
Caudate Lobe
- Only visible on Posterior part of Visceral Surface
- Arises from the Right Lobe
- Left side bound to Ligamentum Venosum
- Right side bound to IVC
Quadrate Lobe
- Located on the Anterior portion of the Visceral Surface
- Left side bound to Ligamentum Teres
- Right side bound to Fossa of Gall Bladder
- Functionally related to/arises from Left Lobe
Ligamentum Venosum
Formerly the Ductus Venosum shunt that bypassed the Liver in fetal circulation
Where is the Gall Bladder Fossa (location in relation to the Liver)?
- On the Visceral Surface (Inferior portion) of the Liver
2. Between Right and Quadrate Lobes
Parts of the Gall Bladder
- Fundus (rounded top part)
- Body (middle, major part in the Gall Bladder Fossa)
- Neck (narrow bottom formed by mucosal folds)
Where is Bile made?
Liver
Where is Bile stored?
Gall Bladder
What does Bile do?
Emulsifies fat (breaks big fat globules into tiny droplets) which is important for digestion
