The chemical and mechanical processes of food breakdown are called digestion. (852-853) 3) The function of the hepatic portal circulation is to collect absorbed nutrients for metabolic processing and storage. (881) 4) When we ingest large molecules such as lipids‚ carbohydrates‚ and proteins‚ they must undergo catabolic reactions whereby enzymes split these molecules. This series of reactions is called chemical digestion. (854) 5) From the esophagus to the anal canal‚ the walls of every

Fast and Easy Digestion - If you are struggling with heartburn and acid reflux issues this is a really important benefit. Juicing provides almost instantaneous digestion. Whereby whole foods can take 2 to 3 hours to complete the digestive process juicing combinations take less than 30 minutes. Juicing retains the digestive enzymes in raw foods

(because it cannot pass through the intestinal walls to the bloodstream and‚ if it could would not be in a useful chemical state. The gut modifies food physically and chemically and disposes of unusable waste. Physical and chemical modification (digestion) depends on exocrine and endocrine secretions and controlled movement of food through the digestive tract. Mouth Mouth Food enters the digestive system via the mouth or oral cavity‚ mucous membrane lined. The lips (labia) protect its outer opening

prevent food from clogging these airways. 16. During digestion‚ enzymes such as amylase break chemical bonds between the sugar monomers in starches. Digestive enzymes also break down foods and make the nutrients available to the body. 17. Mechanical digestion includes the muscles of the stomach contracting to mix stomach fluids and food which produces a mixture known as chyme. Chemical digestion includes the production of acids that aid the digestion and absorption of food. 18. In the stomach‚ hydrochloric

in passing of stool. Faulty digestion and poor absorption of the digested material explains the high solute concentration. Improper balances of the normal micro flora can also result in high concentrations of solute in the lumen because some of the bacteria in the gut aids in adequate and sufficient digestion. Therefore a lack there of would hinder proper function. Dr. Bharucha also mentions that “rapid intestinal transit and diminished surface area impair digestion” therefore leading to diarrhea

The proteins will be flushed out of the body quicker than usual with the high vulnerability of malabsorption. Pepsin begins the enzymatic digestion of the ingested proteins; they linger in the stomach longer than most of the ingested food and the end result of gastric protein digestion is a chyme of mostly polypeptides and some free amino acids to be absorbed in to the body

reintroduces digestive enzymes to the process. Once digestion is completed the nutrients are passed through the intestinal wall and into the bloodstream. For most of us the food entering our stomach is severely enzyme deficient because of processing and cooking. Any food that sustains heat of approximately 118 to 129 degrees fahrenheit destroys the enzymes. The food then sits there for an hour‚ like a heavy lump‚ with very little pre-digestion taking place. This forces the body to produce large

LITERATURE REVIEW INTRODUCTION OF ENZYMES Enzymes are complex proteins that cause a specific chemical change in all parts of the body (David C. Dugdale‚ 2011). When we understand enzymes we understand cells (Marshall Brian‚ 2001). In many organisms most chemical reactions are catalyzed -when a substance speeds up the rate of a chemical reaction- by enzymes. Each enzyme controls a certain function that happens in a cell. Still each one has its own process and rate that it converts molecules. Studying
