The gallbladder contracts in response to what?
Explanation
Cholecystokinin (CCK) is a hormone released by the small intestine in response to the presence of fat and protein in the digestive system. It plays a crucial role in the digestion and absorption of these nutrients. When CCK is released, it stimulates the contraction of the gallbladder, causing it to release bile into the small intestine. Bile aids in the digestion and absorption of fats. Therefore, the gallbladder contracts in response to cholecystokinin (CCK).Rate this question:
- 7.
This layer of the gallbladder wall is the outermost layer of visceral peritoneum
Explanation
The outermost layer of the gallbladder wall is known as the serosa. The serosa is a thin layer of connective tissue that covers the outer surface of many organs in the abdominal cavity, including the gallbladder. It is composed of a single layer of cells called mesothelial cells, which secrete a lubricating fluid to reduce friction between organs. The serosa provides protection to the gallbladder and helps to keep it in place within the abdominal cavity.Rate this question:

Sono AppearanceThe bile duct lumen normally appears _____________ with thin, echogenic walls. Gains may have to be _____________ slightly from those used during hepatic imaging to avoid artifactual filling (pseudo-sludge).
Explanation
The correct answer is "anechoic, decreased". In normal conditions, the bile duct lumen appears anechoic, meaning it appears black on ultrasound due to the absence of echoes. The walls of the bile duct are thin and echogenic, meaning they produce echoes and appear bright on ultrasound. However, during hepatic imaging, the gain settings may need to be decreased slightly to avoid artifactual filling or pseudo-sludge, which can create false echoes and make the bile duct appear filled with sludge.Rate this question:
- 9.
The gallbladder can also be ______ sided (situs inversus)
Explanation
The gallbladder can also be situated on the left side of the body, a condition known as situs inversus. In situs inversus, the organs of the body are mirror images of their normal positions. So, instead of being on the right side, the gallbladder is located on the left side. This is a rare condition that occurs during embryonic development and does not typically cause any health issues.Rate this question:

The ampulla of vater is controlled by the _______________ _______ _______________.
Explanation
The ampulla of Vater is a small muscular structure located at the junction of the common bile duct and the pancreatic duct. It acts as a gateway for the release of bile and pancreatic enzymes into the small intestine. The sphincter of Oddi, a circular muscle, surrounds the ampulla and controls its opening and closing. When the sphincter of Oddi relaxes, it allows the flow of bile and pancreatic enzymes into the intestine for digestion. Conversely, when it contracts, it prevents the backflow of intestinal contents into the ducts. Therefore, the sphincter of Oddi plays a crucial role in regulating the release of digestive fluids from the ampulla of Vater.Rate this question:
- 12.
The branches of the intrahepatic biliary tree converge to form a right and left __________ duct which joins to form the _______________ ______________ _____________.

CCK is responsible for...
-
Contraction of the gallbladder muscularis to force bile into the CBD
-
Relaxation of the sphincter of Oddi
-
Increasing bile flow from liver
Correct Answer(s)
A. Contraction of the gallbladder muscularis to force bile into the CBD
A. Relaxation of the sphincter of Oddi
A. Increasing bile flow from liverExplanation
CCK, or cholecystokinin, is a hormone released by the small intestine in response to the presence of fatty acids and amino acids. It has several functions related to bile and digestion. One of its roles is to stimulate the contraction of the gallbladder muscularis, which helps to force bile into the common bile duct (CBD) and ultimately into the small intestine. Additionally, CCK relaxes the sphincter of Oddi, a muscle that controls the flow of bile and pancreatic enzymes into the small intestine. This relaxation allows for the release of bile into the CBD. Lastly, CCK also plays a role in increasing bile flow from the liver, promoting the production and secretion of bile.Rate this question:
