What are the main functions of the human digestive system?

The human digestive system is a complex system that is responsible for breaking down food and converting it into energy and nutrients that the body can use. The main functions of the digestive system are:

• Ingestion: The process of taking in food through the mouth
• Digestion: The breakdown of food into smaller molecules that can be absorbed by the body
• Absorption: The process of absorbing nutrients and water from the small intestine into the bloodstream
• Transport: The movement of food and waste products through the digestive tract
• Elimination: The removal of waste products from the body in the form of feces

The digestive system involves various organs, including the mouth, esophagus, stomach, small intestine, large intestine, liver, gallbladder, and pancreas. Each organ plays a crucial role in the process of digestion, and any problems with these organs can lead to digestive problems and other health issues.
