DIGESTION OF CARBOHYDRATES Digestion of carbohydrate begins in the mouth‚ with the secretion of the enzyme salivary amylase from the serous cells of the salivary gland. This enzyme breaks starch and glycogen into disaccharides. The mucous cells of the salivary gland secrete a mucus‚ which causes the food to stick together‚ and acts as a lubricant to aid in swallowing. The salivary glands are grouped into three categories: the parotid gland‚ submandibular glands‚ and sublingual‚ all located

To achieve the goal of providing energy and nutrients to the body‚ six major functions take place in the digestive system ingestion‚ Secretion‚ mixing and movement‚ digestion‚ absorption and excretion. There are two kinds of organs that make up the digestive tract are the mouth‚ esophagus‚ stomach‚ small intestine‚ large intestine also called the colon - rectum‚ and anus all of which are hollow. Inside these hollow

Human Digestion SCI/241 Human Digestion The beginning of the digestive process starts with the smell and sight of food which activate the salivary glands. The mouth is the point at which food enters the digestive tract and continues the digestive process by chewing food. The food is then broken down into pieces and moistened by salivary glands which turn food into a bolus. The bolus goes down the pharynx into the esophagus which connects the pharynx to the stomach. The stomach is an organ

metabolized in the body! Digestion is the chemical breakdown of food molecules into smaller molecules that can be used by various cells within the body. The breakdown is initiated when food is ingested in the mouth and specific enzymes are exposed to components within the food molecules. Digestion begins in the mouth with mastication‚ or chewing‚ performed by the teeth. The purpose of chewing is to grant the food more exposure to enzymes‚ therefore allowing chemical digestion to occur faster. The presence

Process of Digestion Over the course of time there have been many difficult questions and theories about everyday life. Using physiology & chemistry‚ those questions have been able to be answered. From the mixture of gases in the air we breathe to the organic substance of plastic or paper‚ chemistry can be seen everywhere. However‚ most people mistook the power of chemistry in our own bodies. How is it that a simple slice of bread‚ once consumed‚ can turn into fuel for the human body? Using

Digestion Lab Abstract – The purpose of this lab was to understand how different solutions played a role in the digestion protein. By looking at different variables‚ such as temperature‚ and pH we’re capable of understanding just how certain substances functioned and when they didn’t. The data for all labs are clear and concise and give a clear understanding of what solutions work best. All three labs were placed in a warm water bath set at 37’C to stimulate the reaction as if it were taking place
