Human Digestive System Glands and Functions

The video explains the digestive process, highlighting the roles of various glands. It begins with the alimentary canal and the importance of chemical digestion. The salivary glands initiate carbohydrate breakdown, followed by the gastric glands in the stomach for proteins. The liver and gallbladder emulsify fats, while the pancreas completes digestion with its enzymes. Each gland contributes uniquely to the digestive process, ensuring nutrients are fully broken down and absorbed.
