What Happens in Our Body When We Eat?
Understanding the Digestive System
- The body cannot use food in its original form; it must modify it through digestion, which separates beneficial components from waste.
- Digestion begins in the mouth where teeth perform mechanical digestion by grinding food, while saliva aids in chemical digestion by softening food.
- The chewed food forms a paste called "bolo alimenticio," which travels down the esophagus to the stomach, where both mechanical and chemical digestion continue with gastric juices.
- In the small intestine, additional digestive juices from the liver and pancreas complete digestion and nutrient absorption into the bloodstream. Waste is processed in the large intestine before elimination.
