HUMAN NUTRITION

Detailed explanation-1: -Liver. The liver has many functions, but its main job within the digestive system is to process the nutrients absorbed from the small intestine. Bile from the liver secreted into the small intestine also plays an important role in digesting fat and some vitamins.

Detailed explanation-2: -Jejunum. The jejunum is the middle part of the small intestine, between the duodenum and ileum. Most digestion and nutrient absorption takes place in the jejunum.

Detailed explanation-3: -The small intestine is where most digestion takes place: most vitamins and minerals, as well as fats and some water, are absorbed in the small intestine. Muscle contractions, called peristalsis, move food through the small intestine as it is digested.

Detailed explanation-4: -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-5: -The small intestine is actually the longest segment of the gastrointestinal tract-the long, continuous pathway that food travels through your digestive system. In the small intestine, food is broken down into liquid and most of its nutrients are absorbed. The waste is passed on to the large intestine.
