Detailed explanation-1: -The digestive system is a group of organs that work together to change the food you eat into the energy and nutrients your body needs. After you consume food and liquids, the digestive system breaks them down into their basic parts: carbohydrates, proteins, fats, and vitamins.

Detailed explanation-2: -The stomach and small intestines absorb the glucose and then release it into the bloodstream. Once in the bloodstream, glucose can be used immediately for energy or stored in our bodies, to be used later. However, our bodies need insulin in order to use or store glucose for energy.

Detailed explanation-3: -The digestive system converts the foods we eat into their simplest forms, like glucose (sugars), amino acids (that make up protein) or fatty acids (that make up fats). The broken-down food is then absorbed into the bloodstream from the small intestine and the nutrients are carried to each cell in the body.

Detailed explanation-4: -The digestive system is made up of the gastrointestinal tract-also called the GI tract or digestive tract-and the liver, pancreas, and gallbladder. The GI tract is a series of hollow organs joined in a long, twisting tube from the mouth to the anus.

Detailed explanation-5: -The digestive system is made up of the digestive tract and other organs that help the body break down and absorb food. It is a long, twisting tube that starts at the mouth and goes through the oesophagus, stomach, small intestine, large intestine and anus.
