Human Digestion Christine Wilkes SCI 241 Natalia Woehl March 8‚ 2011 The human digestion system consists of a series of organs and glads that process the food that we eat. The digestion process starts when food enters the mouth‚ then with the chewing of food. The salivary glads help break down the food with enzymes so that it is easier to swallow. While the food is being chewed it is turned into bolos‚ which then travels down the pharynx and through the esophagus. The esophagus is the long

Digestion and Enzymes – APP. Hypothesis: The enzyme‚ Amylase which is used to break down carbohydrates will work the best when heated at 40°C. Also‚ as the temperature increases the reaction rate of amylase increases too. However‚ the reaction rate of amylase will start decreasing when the temperature reaches the enzyme’s optimal temperature. Many enzymes are specific for a certain substrate. For example‚ lipase is a specific enzyme for fat substrates and protease‚ a specific enzyme for

Digestion/ Absorption and Homeostasis In order to survive‚ our bodies must bring in energy and nutrients for the cells of the body through eating and digestion of food. To be carried to the cells of the body by the blood stream‚ food must be broken down to molecules. This breaking down of food into molecules‚ small enough to be absorbed into and carried through the blood stream‚ is carried out by the digestive system through the process of digestion and absorption. Digestion is the process of

EXPERIMENT 13 DIGESTION IN THE SMALL INTESTINES ------------------------------------------------- ABSTRACT The small intestine serves as the site of major digestive and absorptive processes. In this experiment‚ the action of pancreatic enzymes on representative samples of each food group under different conditions‚ such as increased/decreased pH and presence of other substances‚ were observed. A pancreatin solution was first prepared from a hog pancreas and was completely neutralized using

Defn. of Digestion: the process whereby a biological entity processes a substance‚ in order to chemically convert the substance into nutrients. It usually involves mechanical manipulation and chemical action. Mechanical Digestion What is it? This type of digestion involves the mixing‚ grinding or crushing of large pieces of food into smaller places. Why does it take place? So that the food we consume is broken down into smaller pieces before we swallow it which in turn makes process of

fragments. This step is made possible by the contraction of the muscle of the stomach‚ the muscularis. Composed of three layers of fibers arranged longitudinally‚ circular and oblique‚ it mixes and kneads the food. Then begins the chemical digestion. Only the digestion of proteins begins in the stomach. The mucosa contains glands that secrete gastric juices. Under normal conditions‚ the production of juices is 2 to 3 L per day. Hydrochloric acid and enzymes are also produced by cells of the stomach. All

DIGESTION IN THE MOUTH: Food is mechanically cut by incisors and canines‚ chewed by molars and premolars‚ and mixed with saliva by the tongue. The saliva has been produced by salivary glands‚ which pour it into the mouth through salivary ducts. This process of introducing food into the mouth is called ingestion. Chewing breaks food into smaller particles so that chemical digestion can occur faster. This cutting and mixing is called mastication. Moreover‚ food is chemically digested by salivary
