The common name for the structures that release enzymes in the digestive system is glands. Notable examples include the salivary glands, gastric glands, and pancreas, all of which produce specific enzymes that assist in the chemical breakdown of food. These enzymes help in digesting carbohydrates, proteins, and fats, facilitating nutrient absorption in the intestines. The proper function of these glands is vital for digestive health and overall well-being, as they play a crucial role in the digestive process.
