The Digestive System When we eat such things as bread, meat, and vegetables, they are not in a form that the body can use as nourishment. Our food and drink must be changed into smaller molecules of nutrients before they can be absorbed into the blood and carried to cells throughout the body.

How Does the Human Digestive System Work? The nutrients gained from digested food diffuse through the capillary walls, across the interstitial fluid, and are absorbed by the cells. At the same time, waste produced by the cell’s metabolic processes diffuses out of the cell, across the interstitial fluid, and into the capillary, where it can be carried to the kidney for excretion.

A Look Inside Your Digestive System PIXOLOGICSTUDIO / Getty Images. The digestive system is a collection of organs that work together to digest and absorb food. Digestion is the process your body uses to break the foods you eat down into molecules your body can use for energy and nutrients. The following organs work together to help your body process the foods you eat.

What is Digestion? - Definition & Process Food is the body's fuel source. The nutrients in food give the body's cells the energy and other substances they need to operate. But before food can do any of these things, it has to be digested into small pieces the body can absorb and use. Almost all animals have a tube-type digestive system in which food enters the mouth, passes through a long tube, and exits as feces (poop) through the anus.

Digestive System: Nutrient Absorption Absorption and Transport of Nutrients. Digested molecules of food, water and minerals from the diet, are absorbed from the cavity of the upper small intestine. The absorbed materials cross the mucosa into the blood, and are carried off in the bloodstream to other parts of the body for storage or further chemical change.
