Gallbladder

This video tutorial by Matt from Kenhub focuses on the gallbladder, covering its location, function, anatomy, and associated systems. The gallbladder is a small, green sac located between the liver's lobes, storing and concentrating bile. It has three main parts: the fundus, body, and neck. The bile duct system, including the cystic and common bile ducts, facilitates bile drainage into the duodenum. The gallbladder receives blood from the cystic artery and drains through cystic veins. Lymphatic drainage is managed by hepatic nodes, while innervation involves sympathetic, parasympathetic, and sensory fibers. The video encourages viewers to explore more anatomy resources on Kenhub.

• Next to the pancreas

• Between the left and right hepatic lobes

• Above the left hepatic lobe

• Below the right hepatic lobe

What is the primary function of the gallbladder?

• To filter blood

• To digest proteins

• To store and concentrate bile

• To produce bile

Which part of the gallbladder is closest to the opening?

• Fundus

• Body

• Cystic duct

• Neck

How does the cystic duct regulate bile flow?

• Using a pressure gradient

• Through a muscular valve

• Via the spiral valve

• By gravity

Which nerve provides parasympathetic innervation to the gallbladder?

• Celiac plexus

• Sympathetic trunk

• Right phrenic nerve

• Vagus nerve
