Structure and Function of the Digestive System
Anatomy of the gastrointestinal tract, including organs such as the mouth, esophagus, stomach, intestines, liver, and pancreas
The digestive system is responsible for processing food, absorbing nutrients, and excreting waste. It includes organs such as the mouth, stomach, intestines, liver, and pancreas.
Structure and Function of the Digestive System
The digestive system plays a crucial role in breaking down food and absorbing essential nutrients. It consists of multiple organs working in harmony to process food from ingestion to excretion.
Anatomy of the Digestive System
Mouth
The digestive process begins in the mouth, where teeth mechanically break down food, and saliva begins chemical digestion.
Esophagus
The esophagus transports food from the mouth to the stomach through peristalsis.
Stomach
Gastric juices containing hydrochloric acid and enzymes break down food into a semi-liquid substance called chyme.
Small Intestine
The primary site of nutrient absorption, the small intestine consists of three sections: duodenum, jejunum, and ileum.
Large Intestine
The large intestine absorbs water and forms feces before excretion through the rectum.
Accessory Organs
The liver, pancreas, and gallbladder assist digestion by producing bile and enzymes.
Functions of the Digestive System
- Ingestion: The intake of food.
- Digestion: Breaking down food mechanically and chemically.
- Absorption: Transporting nutrients into the bloodstream.
- Excretion: Removal of waste products.
Proper digestive health is essential for overall well-being. Maintaining a balanced diet and staying hydrated can support digestive functions.
