The digestive system breaks down food into nutrients that the body needs. It has four main steps: ingestion, digestion, absorption, and elimination. The major organs include the tongue, salivary glands, liver, gallbladder, pancreas, esophagus, stomach, intestines, and rectum. The digestive system interacts with the excretory system to remove waste and the musculoskeletal system by providing nutrients for proper functioning and health. Maintaining homeostasis requires the essential nutrients provided by the digestive system like vitamins, minerals, calories, and energy. Common diseases include obesity, anorexia, bulimia, and diabetes which can result from improper eating habits.
