    The digestive system is a complex network of organs responsible for breaking down food, absorbing nutrients, and eliminating waste from the body. Its primary function is to convert the food we eat into energy and essential molecules needed for growth, repair, and overall bodily functions. The digestive system works like a processing factory, transforming food into usable nutrients while efficiently discarding waste. Therefore, it is an essential to understand its structure and function to comprehend nutrient absorption, metabolic  processes and related pathologies.

      Topic: Digestive System

      Objective: Collaborate in small groups to discuss key questions about digestion, ensuring clear explanations and respectful dialogue.

      Instruction: Divide among yourself into groups. Discuss within your group members based on the following questions. Aim for clear, concise answers with examples, where needed.

      1. How does the structure of the small intestine relate to its function in absorption?
      2. Compare the mechanical and chemical digestion, giving examples of each.
      3. Why is the stomach lining protected from its own acidic environment? What happens if this protection fails?
