Digestion define as a process where foods been breaking down by enzymatic action in the Gastrointestinal tract (GI tract) into nutrients in preparation for absorption. GI tract is the flexible muscular tube from mouth to anus. The digestion of carbohydrates begin in the mouth‚ where an enzyme‚ salivary amylase (α-amylase;ptyalin) starts to breaking the polysaccharides (starch) into short polysaccharides (dextrin). Dextrin is a partial degradation of starch‚ shorter chains of maltose units. Salivary

Respiration‚ digestion and rocks Respiration Respiration is a chemical reaction that happens in all living cells. It is the way that energy is released from glucose‚ for our cells to use to keep us functioning. Remember that respiration is not the same as breathing (which is properly called ventilation). The glucose and oxygen react together in the cells to produce carbon dioxide and water. The reaction is called aerobic respiration because oxygen from the air is needed for it to work. Digestion

Lipid Digestion The process of mastication is our only conscious act in the digestion of the foods we consume. After that‚ it’s out of sight‚ out of mind; but should it be? What does it take to transform that last swallow into the energy our body needs to sustain itself? In the case of lipid digestion‚ the real magic occurs throughout the gastrointestinal tract with a synergistic collaboration from the accessory organs: the liver‚ gallbladder and pancreas. Understanding the whole process of digestion

Another way to do this part would be to write out the parts and put a location/description next to it. The second part of Part 2 for this section is to describe the manner in which you will retain the information of where each body part is located. An example would be‚ "I will remember the location of each body part by reviewing the photo and memorizing each location." Some

during grazing. Cattle pick up feeds during grazing by grasping and gathering the plants with their tongues and pulling them to tear for consumption. On average‚ cattle take from 25‚000 to over 40‚000 prehensile bites to harvest forage while grazing each day. They typically spend over 30 percent of their time grazing‚ another 30 percent of their time chewing cud‚ and the rest of their time idling where they are not grazing or chewing cud (Hall‚ 9). The roof of their mouth is a hard dental pad without

“A mouth is a part of the body where people use mechanical digestion and use their teeth to break down their food. With the help of saliva produced by the salivary glands‚ which produce enzymes‚ food is able to be broken down further. This is also the place where ingestion takes place” “What are enzymes” “Enzymes are very efficient catalysts for biochemical reactions. In the mouth there’s an enzyme that will help your food undergo chemical digestion” “What is it” “It is amylase. Which help digest

Checkpoint: Human Digestion SCI/241 June 4‚ 2013 The path that food follows through the digestive system is very interesting. First you put the food to your mouth‚ take a bite‚ and chew. The salivary glands begin the digestive process at the sight and smell of food. After food enters the mouth and is moistened by saliva‚ it transforms into a bolus. Once the bolus leaves the mouth‚ it moves into the pharynx‚ where it can be swallowed. The bolus then moves from the pharynx to the stomach
