Digestive System Functions and Anatomy

The video tutorial explores the anatomy and functions of the abdominal cavity, focusing on organs such as the liver, gallbladder, spleen, pancreas, and intestines. It explains the digestive process, including the roles of bile and enzymes, and highlights the importance of nutrient absorption and waste formation. The tutorial also covers the structure of the mesentery and the function of sphincters in controlling food passage.

What is the primary function of the liver in the digestive system?

• To produce insulin

• To process nutrients

• To store bile

• To break down red blood cells

Where is bile stored before it is released into the small intestine?

• In the gallbladder

• In the pancreas

• In the liver

• In the spleen

What is the role of the spleen in the body?

• To regulate blood glucose levels

• To produce digestive enzymes

• To break down red blood cells

• To store bile

Which organ is responsible for secreting enzymes into the small intestine?

• Spleen

• Pancreas

• Gallbladder

• Liver

What is the function of the cardiac sphincter?

• To regulate blood glucose

• To prevent backflow of food

• To control bile release

• To store digestive enzymes

What is the function of the pyloric sphincter?

• To store digestive enzymes

• To regulate bile release

• To control food entry into the stomach

• To control chyme entry into the small intestine

Where does the majority of nutrient absorption occur?

• In the small intestine

• In the stomach

• In the pancreas

• In the large intestine

What is the primary role of the mesentery?

• To hold intestines together

• To produce insulin

• To break down red blood cells

• To store bile

Which part of the intestine is responsible for compacting fecal matter?

• Large intestine

• Jejunum

• Duodenum

Which section of the small intestine directly follows the stomach?
