Human Digestion Activity The digestive process involves the mixing of food‚ the movement of food through the digestive tract‚ and a chemical breakdown of large molecules of food into smaller molecules. The digestive system is made up of the digestive tract and other organs that aid in digestion. The digestive tract is a series of hollow organs joined in a long‚ twisting tube from the mouth to the anus. Those twisted tubes include the mouth‚ esophagus‚ stomach‚ small and

known. Yeast is also a probiotic substance. But only certain types of bacteria or yeast (called strains) have been shown to work in the digestive tract. Probiotics are also available as dietary supplements. Lactobacillus and Bifidobacteria Lactobacillus and Bifidobacteria is a type of bacteria. These are "friendly" bacteria that normally live in our digestive‚ urinary‚ and genital systems without causing disease. Lactobacillus is also found in some fermented foods like yogurt and in dietary

1) The mechanical and chemical receptors that control digestive activity are located in the walls of the GI tract organ. (854) 2) 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

Project 3.2.2: Digestive System Design Introduction During his or her lifetime‚ the average person eats his/her way through at least 20 tons of food. Meats‚ vegetables or sweets - whatever your diet‚ that’s 40‚000 pounds! Our digestive system works to turn this enormous amount of food into substances that the body can use for energy and for growth and repair. But what actually happens to these foods once they enter our bodies? How does the body process each tasty bite and harness the power locked

The MOUTH is the starting point that begins the digestive process. The TONGUE is used for grasping the food‚ mixing‚ and swallowing. The TEETH tear and chew the feed into smaller particles that may be swallows.

grains‚ pomegranates‚ vegetables and other fruits. Phase two of liver detoxification involves adding to the produced harmless substances from phase one to make them soluble in water. Once they are water-soluble‚ they can then be passed into the digestive tract and ejected through urination or bowel movement. To best way convert these harmless products is through the use of sulfur. Take foods rich in sulfur such as eggs‚ cauliflower‚ cabbages and broccoli. Colon cleansing The easy way to do colon

Yakult? Yakult is a fermented milk drink made by fermenting skim milk powder and sugar with the beneficial bacteria Lactobacillus casei Shirota strain. This bacterium helps to replenish the good bacteria in the small intestine‚ ensuring that our digestive system works efficiently and effectively. Is Yakult artificially coloured? No. The colour of Yakult is naturally acquired when the skim milk powder and sugar are heated together at high temperatures‚ prior to fermentation. Are there any preservatives

There is another accessory organ that also dumps its products into the duodenum around the same area; this organ is called pancreas. Pancreas is very important‚ as it secretes probably the most important digestive enzymes into the small intestine; break down. The main enzymes secreted by the pancreas for digestion are lipases for lipid/fat digestion‚ pancreatic amylase for carbohydrate digestion which continues the breakdown of the starch in the bread to a substance called maltose.
