What is the primary function of the digestive system?

The primary function of the digestive system is to break down food and absorb nutrients. This system encompasses a series of organs that work collaboratively to process food from ingestion to elimination. It begins with mechanical digestion in the mouth, where food is chewed and mixed with saliva, followed by chemical digestion in the stomach and intestines. As food passes through the digestive tract, it is broken down into smaller molecules, which are then absorbed through the intestinal walls into the bloodstream. Nutrients, such as carbohydrates, proteins, fats, vitamins, and minerals, are essential for the body’s growth, repair, and overall function. Without the proper functioning of the digestive system, the body would be unable to obtain the necessary nutrients required for energy and health.
