Digestive Anatomy and Functions Explained

The video tutorial provides a comprehensive overview of the human digestive system, starting from the oral cavity and salivary glands, moving through the esophagus, stomach, small and large intestines, and ending with the rectum and anus. It explains the roles of various organs, including the liver, gallbladder, and pancreas, in digestion and nutrient absorption. The tutorial also covers the function of sphincters in controlling the passage of food and preventing acid reflux. A 3D model is used to visually demonstrate the positioning of these organs.

What is the primary function of the salivary glands?

• To produce bile

• To produce saliva

• To absorb nutrients

• To store food

Where does food travel after it leaves the oral cavity?

• Into the small intestine

• Directly to the stomach

• Into the large intestine

• Into the esophagus

What is the role of the lower esophageal sphincter?

• To control the release of bile
