The digestive system is a complex physiological system in the human body responsible for breaking down food into nutrients that can be absorbed and used for energy and essential bodily functions.
It includes organs such as the mouth, esophagus, stomach, small intestine, large intestine, liver, pancreas, and gallbladder, each with specific roles in digestion and nutrient absorption.
The digestive process involves mechanical and chemical processes, including the secretion of enzymes and digestive juices, to convert food into nutrients like carbohydrates, proteins, and fats. This system plays a vital role in sustaining life and maintaining overall health.
