Next, the broken down food passes through the esophagus into the stomach. Peristaltic movements allow the food to move through the body. The stomach is the site of most protein digestion. The churning mechanism of the stomach further breaks down the food, and releases acids and enzymes for chemical break...

...testine has a number of portions, but the beginning is called the cecum. The cecum mainly functions to absorb fluid and salts. In the large intestine, water is mainly absorbed from the indigestible matter and then sent to the rectum and then anus, which work to expel the waste from the body (Britannica, “Large Intestine”).
Based on the functions and descriptions of the enzymes mentioned above, the hypothesis if this experiment is that in the protein lab, only that tube containing the egg white, pepsin, and hydrochloric acid will cause digestion of the egg white because it most closely mimics environment of the stomach. In the fat/lipase lab, the 2 tubes containing cream and lipase and cream lipase, and bile salts will only demonstrate digestion of fats. In the starch lab, the only tube that will show digestion will be the tube containing starch and amylase at 37°C

- Enzymes are protein based molecules that help to speed up reactions in other molecules. They cause reactions without being used up or changing after the reaction is completed. Enzymes are the body’s workers and they are produced by all living things. Enzymes are made of chains of amino acids. The amino acids are linked in specific ways to complete whichever job they were made to do. Each enzyme was built for a different job and will only work with a specific substance. The efficiency of enzymes is dependant on the temperatures that enzymes are exposed to.... [tags: metabolic enzymes, digestive enzymes, biology,]

- The digestive system is a group of organs that perform the process of digestion, which is food, containing nutrients, is eaten and broken down into different components. This whole system is designed uniquely to perform to turn food into energy you need to survive. The digestive system starts with the mouth and ends with the anus. The mouth being the very beginning of the digestive tract is literally when the first bite of food is taken. Chewing up food breaks the food into little pieces, while saliva mixes with the food to begin the process of breaking it down.... [tags: Digestion, Digestive system, Stomach]

- The overall purpose of the digestive system The digestive system has of a chain of linked organs that work with each other to digest, and break down food into molecules that are put in the circulatory system. Then takes them to the body’s tissues. The most important structures in the digestive system are the tongue, mouth, intestines, esophagus, stomach, and anus. The liver, gallbladder, and pancreas are with the digestive system also. How does the digestive system function Food comes in the mouth, and chewing and saliva start to break it up and make it smaller to swallow.... [tags: Digestion, Stomach, Digestive system]

- The digestive system is one of the most important parts of the human body because it is the way that we are able to absorb all the nutrients that we need in order to survive. Jane Doe is a diabetic who just had a turkey sandwich on whole wheat bread with mayonnaise, lettuce, and tomatoes, with a side of potato chips and apple juice to drink. This may not have been the best decision because of her disease. As we explore the six steps of the digestive system we will learn why not. The digestive system consists of six steps starting at the mouth and ending at the large intestine.... [tags: Digestion, Stomach, Digestive system]

- The digestive system is a group of organs working together to convert food into energy and basic nutrients to feed the entire body. Food passes through a long tube inside the body known as the gastrointestinal tract (GI tract). The gastrointestinal tract is made up of the oral cavity, pharynx, esophagus, stomach, small intestines, and large intestines. In addition to the GI tract, there are several important accessory organs that help your body to digest food, but do not have food pass through them.... [tags: Stomach, Digestion, Digestive system]

- The oral cavity is the first part of the digestive system, it is basically the mouth containing the teeth, the tongue, salivary glands, uvula, and the pharynx. When food enters the mouth it is welcomed by the teeth which immediately start the mechanical digestion that occurs in the mouth. The teeth work along with the tongue to turn the food into bolus (small rounded masses of chewed food). While the food is being chewed and moved around the salivary glands secrete saliva, which has the purpose of helping break down the food into simpler molecules and make it easier to be swallowed....

- Introduction In this dissection that was conducted there were aims to be able to do within the dissection for example; to identify all organs in the pig and sheep’s digestive systems, describe the internal structures of different organs, and link the function to the structure. Method The dissection included the digestive system of a pig and sheep. The first part examined was the oesophagus an incision was made along the oesophagus to be able to examine inside the oesophagus. The next incision was made from the oesophagus down towards the stomach to be able to observe how the oesophagus changes.... [tags: Stomach, Digestion, Digestive system, Ruminant]

- The human digestive system is a bodily process made up of many systems, organs and substances that break down food both physically and chemically for use by the body. But what exactly is human digestion and what happens to food as it moves through the digestive system. “…[digestion] is a group of organs working together to convert food into energy and basic nutrients to feed the entire body” (Tim Taylor). There are three major bodily mechanisms that contribute to the process of digestion. The first mechanism is the breakdown of food, the second mechanism is the process of extracting nutrients from food, and the third mechanism is excretion, or the body’s natural waste system....

- Enzymes are protein molecules that are made by organisms to catalyze reactions. Typically, enzymes speeds up the rate of the reaction within cells. Enzymes are primarily important to living organisms because it helps with metabolism and the digestive system. For example, enzymes can break larger molecules into smaller molecules to help the body absorb the smaller pieces faster. In addition, some enzyme molecules bind molecules together. However, the initial purpose of the enzyme is to speed up reactions for a certain reason because they are “highly selective catalysts” (Castro J.... [tags: Enzyme, PH, Enzyme substrate, Chemistry]

- ... The substrate is then broken down into smaller molecules which our body can then absorb. The name ‘amylase’ is the name typically given to enzymes that break down starch. When rice is eaten by humans, our salivary glands secrete an enzyme called amylase. Amylase, however, can only digest starch which is abundant in cooked white rice. The digestion process only begins again once the stomach content is passed into the first section of the first intestine where more amylase is made available due to the pancreas that secretes it once the contents has passed through the stomach....
