ANATOMY

Detailed explanation-1: -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. Unused materials are discarded as faeces (poo).

Detailed explanation-2: -Your digestive system breaks nutrients into parts small enough for your body to absorb and use for energy, growth, and cell repair.

Detailed explanation-3: -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-4: -Key Points Two important functions of the digestive system are digestion and absorption. The nutrients that come from food are derived from proteins, fats, carbohydrates, vitamins, and minerals. These complex macromolecules must be broken down and absorbed in the gastrointestinal (GI) tract.

Detailed explanation-5: -The Digestive System is responsible for the breakdown of food in smaller components until they absorbed in body and generates energy.
