ANATOMY

Detailed explanation-1: -A digestive system is a group of organs working together to convert food into energy and basic nutrients to feed the entire body.

Detailed explanation-2: -Food enters the mouth and passes to the anus through the hollow organs of the GI tract. The liver, pancreas, and gallbladder are the solid organs of the digestive system. The digestive system helps the body digest food.

Detailed explanation-3: -The circulatory system is one of the eleven organ systems of the human body. Its main function is to transport nutrients to cells and wastes from cells (Figure 3.12 “Cardiovascular Transportation of Nutrients”). This system consists of the heart, blood, and blood vessels.

Detailed explanation-4: -The blood carries nutrients such as vitamins, minerals, sugars, fats and proteins around the body. Digested nutrients are absorbed into the blood through capillaries in the small intestine. They are then moved to the cells around the body where they are needed.
