ANATOMY

Detailed explanation-1: -The digestive system breaks down the food we eat into tiny parts to give us fuel and the nutrients we need to live. As food breaks down, we get amino acids from protein, simple sugars from starches, and fatty acids and glycerol from fats.

Detailed explanation-2: -Pancreas. Your pancreas makes a digestive juice that has enzymes that break down carbohydrates, fats, and proteins. The pancreas delivers the digestive juice to the small intestine through small tubes called ducts.

Detailed explanation-3: -Small intestine. The walls of the small intestine absorb the digested nutrients into the bloodstream. The blood delivers the nutrients to the rest of the body.

Detailed explanation-4: -The digestive system is made up of the alimentary canal (also called the digestive tract) and other organs, such as the liver and pancreas. The alimentary canal is the long tube of organs-including the esophagus, stomach, and intestines-that runs from the mouth to the anus.
