Béltraktus

Béltraktus is a term that refers to the digestive tract, also known as the gastrointestinal tract or alimentary canal. It is a continuous, muscular tube that begins at the mouth and ends at the anus. Its primary function is to digest food, absorb nutrients, and eliminate waste products from the body.

The béltraktus is composed of several specialized organs, each with a specific role in digestion. It starts with the mouth, where food is mechanically broken down and mixed with saliva. From the mouth, food passes through the pharynx and esophagus to the stomach, a J-shaped organ that further digests food with the help of acids and enzymes.

Following the stomach, food enters the small intestine, where the majority of nutrient absorption occurs. The small intestine is a long, coiled tube divided into three sections: the duodenum, jejunum, and ileum. Bile from the liver and digestive enzymes from the pancreas aid in breaking down carbohydrates, proteins, and fats.

The undigested material then moves into the large intestine, where water is absorbed, and waste is formed into feces. The large intestine includes the cecum, colon, rectum, and anal canal. Finally, waste is expelled from the body through the anus. The béltraktus is a complex system essential for maintaining life and health.
