The foods we eat—apples, pepperoni pizzas, leafy green salads—taste good to us, but cannot be used by the body as they are. The nutrition the cells of the body need to keeping growing and working must be in a simple form: amino...
Digestive Disorders Disorders that affect one or more of the organs and glands that make up the digestive system. The digestive system consists of organs—the mouth, esophagus, stomach, and small and large intestines—and...
At the beginning of the 1800s the process of digestion was a mystery wrapped in conjecture and debate. During the nineteenth century, however, four men contributed important pieces toward solving the puzzle of digestion. American William Beaumont...
Digestion is the physiological process by which food is broken down, mechanically and chemically, into particles small enough to pass through the walls of the intestinal tract and into the blood. Once in the bloodstream, these tiny particles can then...

Digestion is the process of breaking down food into molecules that cells can absorb. Carbohydrates, proteins, nucleic acids, and fats are broken down into their smallest units (monomers) by digestive enzymes. These hydrolytic enzymes break chemical...
The process by which substances are taken into the tissues of organisms is called absorption. It is essential to functions such as digestion, circulation, and respiration. During digestion, valuable nutrients are absorbed across the epithelial lining...
Absorption, or more generally "sorption," is the process by which one material (the sorbent) takes up and retains another (the sorbate) to form a homogenous concentration at equilibrium. The general term is "sorption,"...
The cephalic reflexes of digestion are those AUTONOMIC and ENDOCRINE rcflexes involved in the metabolism of food that are triggered by sensory contact with food rather than by postingestional mechanisms. They are such things as salivation and INSULIN...
Digestion is one of the four stages through which food is processed: these are ingestion digestion, absorption and elimination. Ingestion is the act of FEEDING; digestion is the process of degrading food components into their MOLECULE constituents for...
Digestion is the process of metabolism whereby a biological entity processes a substance in order to chemically and mechanically convert the substance for the body to use. Preparation for digestion begins with the cephalic phase producing saliva and...
