Goes to the digestive system and then we excrete it as waste

Detailed explanation-1: -Once foods are broken into small enough parts, your body can absorb and move the nutrients to where they are needed. Your large intestine absorbs water, and the waste products of digestion become stool. Nerves and hormones help control the digestive process.
Detailed explanation-2: -As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules. The body then absorbs these smaller molecules through the walls of the small intestine into the bloodstream, which delivers them to the rest of the body.
Detailed explanation-3: -Small intestine It’s largely responsible for the continuous breaking-down process. The jejunum and ileum lower in the intestine are mainly responsible for the absorption of nutrients into the bloodstream. Contents of the small intestine start out semi-solid and end in a liquid form after passing through the organ.
Detailed explanation-4: -When we eat, food passes down the oesophagus and into the stomach, where gastric (digestive) juices break it down further into a porridge-like consistency. The partly digested food then moves through the small intestine (also known as the small bowel).
Detailed explanation-5: -The digestive system breaks down food into nutrients such as carbohydrates, fats and proteins. They can then be absorbed into the bloodstream so the body can use them for energy, growth and repair.
