How do digestive system work??br 3D animation| br #viralbr #shortsbr #shortsfeedsbr #digestivesystembr how the digestive system worksbr br The digestive system breaks down food into essential nutrients for energy and growth. It starts in the mouth, where teeth chew food into smaller pieces and saliva containing enzymes begins decomposition. Swallowed food travels down the esophagus into the stomach, where stomach acid and digestive enzymes further break it down. The partially digested food, now called chyme, enters the small intestine, where most nutrient absorption occurs through tiny finger-like projections called villi. Nutrients are absorbed into the bloodstream and transported to the liver for processing and distribution. The remaining waste moves into the large intestine, also known as the colon, where water and electrolytes are absorbed. The colon houses trillions of beneficial bacteria, aiding in vitamin production and immune function. The remaining waste forms feces, eliminated through the anus during defecation. The digestive process is facilitated by muscles contracting and relaxing in a wave-like motion called peristalsis. Hormones and enzymes regulate digestion, ensuring proper nutrient absorption and waste elimination. The entire process takes around 40-72 hours, varying depending on factors like diet, age, and health.
