Accessory Organs of the Small Intestine [Liver, Gallbladder, & Pancreas]

The video explores the digestive processes in the small intestine, focusing on the roles of the pancreas, liver, and gallbladder. It explains how the pancreas secretes enzymes and bicarbonate to aid digestion and neutralize stomach acid. The liver produces bile, which is stored in the gallbladder and released into the duodenum to emulsify fats, facilitating their digestion and absorption. The video also discusses the hormonal regulation of these processes, highlighting the importance of cholecystokinin in activating the gallbladder and pancreas during digestion.

What is the primary function of the pancreas in digestion?

• To secrete digestive enzymes and bicarbonate

• To absorb nutrients

• To store bile

• To produce insulin and glucagon

Why does the pancreas secrete bicarbonate into the duodenum?

• To aid in fat digestion

• To activate pancreatic enzymes

• To emulsify fats

• To neutralize stomach acid

What is the role of bile in the digestive process?

• To emulsify fats for easier digestion

• To neutralize stomach acid

• To digest proteins

• To absorb carbohydrates

Where is bile stored before it is released into the duodenum?

• In the small intestine

• In the liver

• In the gallbladder

• In the pancreas

What triggers the release of bile and pancreatic enzymes into the duodenum?

• The presence of vitamins

• The presence of proteins

• The presence of fats

• The presence of carbohydrates

Which hormone is responsible for activating the gallbladder and pancreas during digestion?

• Insulin

• Glucagon

• Cholecystokinin

• Gastrin

What is the function of the common pancreatohepatic duct?

• To absorb nutrients

• To transport bile and pancreatic enzymes to the duodenum

• To produce digestive enzymes

• To store bile
