What are the digestive organs in the human body?

The human digestive system mainly includes the mouth, esophagus, stomach, small intestine, large intestine, and anus, along with accessory organs such as the liver, pancreas, and gallbladder. The mouth is the beginning of the digestive tract, responsible for chewing food and initiating the digestion of starches. The esophagus transports food to the stomach through peristalsis. The stomach, one of the main organs of the digestive tract, stores food, secretes gastric acid and digestive enzymes, and breaks food down into chyme. The small intestine is the primary site for digestion and absorption, divided into the duodenum, jejunum, and ileum, responsible for further breaking down food and absorbing nutrients. The large intestine includes the cecum, colon, and rectum, mainly responsible for absorbing water and electrolytes and forming feces. The anus, the terminal part of the digestive tract, expels feces. The liver secretes bile, which aids in the digestion and absorption of fats. The pancreas produces pancreatic juice containing various digestive enzymes, helping digest carbohydrates, proteins, and fats. The gallbladder stores and concentrates bile, releasing it into the small intestine during meals.

To maintain a healthy digestive system, the following measures are recommended: maintain regular eating habits and avoid overeating; consume more fiber-rich foods such as vegetables, fruits, and whole grains to promote intestinal motility; limit intake of greasy, spicy, and highly irritating foods to reduce gastrointestinal irritation; maintain adequate water intake to aid digestion and excretion; engage in moderate physical activity to support intestinal function; and maintain a healthy mindset to reduce the impact of stress on the digestive system. If symptoms of indigestion persist or worsen, seek timely medical attention for professional evaluation and treatment.
