The gallbladder’s function is to store bile from the liver which is delivered through the cystic (bile) duct. The cystic artery is also connected to the gallbladder to deliver blood. (Correct me if I am wrong about any of this.)
However, when I was watching a gallbladder surgery video on YouTube, in the process of removing the gallbladder the surgeon clips the bile duct and artery which I understand but he/she also cauterises the gallbladder off the liver. I also understand that The cauterisation is to prevent bleeding.
BUT the question is WHY is the gallbladder attached to the liver in the first place? WHAT purpose does being attached to the liver serve? Does it provide stability? Because I always thought the gallbladder just sits beneath the liver. Most importantly, HOW is the gallbladder connected to the liver? (This maybe be more of a chemistry question), what bonds is it connect through, what/which biomolecule connects it and why is it that biomolecule/ bond that is used.
As watching the video, I also noted that the surgeon didn’t clip the cystic vein, or even mentioned it. Maybe I am wrong and he/she did clip the cystic vein but I didn’t see, would you also be kind enough to explain to me why the surgeon didn’t clip the cystic vein or if he did why it wasn’t pointed out. Also tell me more about the cystic vein where is it located because it’s very hard to find clear diagrams with them...(is it because it’s small)
