Disorders in the digestive system

Digestion

Digestion is the process by which the body breaks down food into smaller, simpler substances that can be absorbed and used for energy, growth, and repair. This process involves both mechanical (e.g., chewing and churning) and chemical (e.g., enzymes and acids) breakdown of food.

1. Digestion begins in the mouth, continues in the stomach, and ends in the small intestine, where nutrients are absorbed.
2. Undigested food is stored in the large intestine before being expelled as faeces through the anus.
3. Each organ in the digestive system has a specific function, working together to break down food.
4. Poor eating habits can cause digestive disorders, such as:
   • Indigestion Difficulty in digesting food, causing discomfort.
   • Heartburn A burning sensation due to acid reflux.
   • Stomach ulcers Painful sores in the stomach lining.
