The digestive system is responsible for breaking down food, absorbing nutrients, and eliminating waste. It consists of various organs working together to process food efficiently and supply the body with essential nutrients.
Digestion begins in the mouth, where food is chewed (mechanical digestion) and mixed with saliva containing enzymes like amylase (chemical digestion).
A muscular tube that transports food from the mouth to the stomach via peristalsis (wave-like contractions).
The stomach produces gastric juices, including hydrochloric acid and enzymes, to break down food into a semi-liquid substance called chyme.
Comprising three sections (duodenum, jejunum, and ileum), the small intestine is where most digestion and nutrient absorption occur with the help of bile and pancreatic enzymes.
The liver produces bile, which helps digest fats. It also plays a role in detoxification and metabolism.
Stores and releases bile into the small intestine to aid in fat digestion.
Secretes digestive enzymes and bicarbonate to neutralize stomach acid and facilitate nutrient breakdown.
Absorbs water and electrolytes while forming and storing feces for elimination.
The digestive system is essential for overall health, as it ensures proper nutrient absorption and waste elimination. Understanding its functions and maintaining digestive health through proper diet and lifestyle choices can prevent many gastrointestinal issues.
