A Model Intestine
Introduction: Appropriate Background Information
1. What happens in the small intestine?
The small intestine is mainly involved in the digestion. To help the intestine digest, it requires the use of chemical digestion for it to occur. After digestion occurs, some of the nutrients would be absorbed into the blood stream.
2. What is chemical digestion?
Chemical digestion is the process of digestions which requires the use of some type of chemical, such as saliva. Beginning at the mouth, saliva is used as the beginning component of chemical digestion. On the other hand, chewing is not a chemical digestion as it is a voluntary movement.

Since there was not much water there, the glucose would not occur as the water would only create a less concentrated soulution.
11. Compare what happened in this experiment with what happens in the small intestine.
When comparing the differences between the experiment and the small intestine there is not much of a difference, between them. The experiment and the small intestine both contain substances that would normally be found. On the other hand, the intestine is a functioning organ, but the experiment, is not alive. This makes the intestine have more functions than the experiment.
12. Explain why starch cannot be used by the body until it has been digested.
The reason that starch cannot applied by the body until it is digested is because, the sugar is inside the starch and the rest of the starch may be waste. This means that some of the food may not have been filtered properly and it can intoxicate the body. The other reason that starch cannot be used before digestion is because, the body only needs the sugar from the starch and the rest may just be waste. The important materials for the body is only the sugar so the organs could function
The unknown bacterium that was handed out by the professor labeled “E19” was an irregular and raised shaped bacteria with a smooth texture and it had a white creamy color. The slant growth pattern was filiform and there was a turbid growth in the broth. After all the tests were complete and the results were compared the unknown bacterium was defined as Shigella sonnei. The results that narrowed it down the most were the gram stain, the lactose fermentation test, the citrate utilization test and the indole test. The results for each of the tests performed are listed in Table 1.1 below.
During digestion, the body breaks down food into smaller molecules that could then be used by the body’s cells and tissues in order to perform functions. This starts off in the mouth with the physical movements of chewing and the chemical breakdown by saliva. Enzymes in the stomach break food down further after traveling from the mouth through the esophagus. The food from here then moves into the small intestine, where pancreatic juices and enzymes dissolve proteins, carbohydrates, and fibers, and bile from the liver breaks down fats into these small molecules. Any portion of the fibers or food that were unable to be broken down are passed from the small intestine to the large intestine, which is where the digestive tract transitions into the excretory tract, then the colon and out of the rectum. Any liquids that have been stripped of their nutrients by the body proceed from the stomach to the kidneys. In the kidneys, sodium ions (Na+), uric acid, and urea are exchanged with water, which moves urinary bladder and is excreted through the

The dog’s small intestine is split in to three parts. The first part is called the duodenum, in here chemical degradation of chime starts in here. It is caused by the enzymes which are secreted by the duodenum and the pancreas. Bile; which is produced by the dog’s liver and stored in to the gallbladder; helps to break down the fats and help to neutralise acid which was from the stomach. The second and third part of the small intestine for the dog is the jejunum and ileum. The jejunum and ileum surface area increase due to the plica circulares; this is circular folds; which carry villi. Each one of these villi’s has a capillary and a lymphatic capillary (lacteal), this absorbs the digested food through rich venous and capillary drainage of the gut. Whereas the horse’s small intestine are the major organ in their digestion system. They are 70 feet long and can hold up to 12 gallons. In their small intestine pancreatic enzymes help to digest their food. It will digest starches, digest sugars and carbohydrates. In there is also protease which help to emulsify proteins in to amino acids. The horse does not have a gallbladder like the dog does; this mean the bile constantly flows in to their small intestines. The bile helps to break down fats and to suspend the fats in the water. The food then which has be digested will be absorbed through the walls of the small intestine and carried through the blood stream to
Absorption is the way of digesting the food molecules into the small intestine. This process of absorption pass throughout the wall of the small intestine into the bloodstream. The bloodstream carried out all important nutrients to the
The digestive system, in organisms like the mink and human, is supposed to break down the food being eaten to transfer into energy. This energy helps other functions of the body that would in turn keep it alive. The digestive system includes organs such as the stomach, intestines, liver, etc. Digestion starts at the mouth, though.
The small intestine empties into the cecum. The cecum along with the large colon make up the large intestine.

The digestive system otherwise known as the gastrointestinal tract (GI tract) is a long tube which runs from the mouth to the anus. It operates to break down the food we eat from large macromolecules such as starch, proteins and fats, which can’t be easily absorbed, into readily absorbable molecules such as glucose, fatty acids and amino acids. Once broken down, these molecules can cross the cells lining the small intestine, enter into the circulatory system and be transported around the body finally being used for energy, growth and repair.
4)Stomach: The stomach squeezes and mixes food with enzymes for hours before it releases the mixture into the small intestine.
Digestion occurs in the gastrointestinal system, which is composed of the gastrointestinal tract (GI tract) and the associated accessory organs. The process of digestion occurs through six steps, namely ingestion, secretion, mixing, digestion, absorption and defecation. (Tortora & Derrickson, 2008).
Digestion is defined as the process of transforming foods into unites for absorption. The Digestive System is a complex network of organisms that have six major processes: The digestion of food, the secretion of fluids and digestive enzymes, the mixing and movement of food and waste throughout the body, the digestion of food into smaller pieces, the absorption of nutrients, and the excretion of wastes (Inner Body (1).)
The whole purpose of your digestion system is to break down and absorb the energy and nutrients it needs from the food you eat. The sandwich, strawberries, and orange juice you have just consumed is going through this process right now! The process of digestion begins with ingestion, this is when you take a bite of what you have planned to eat. When you took a bite of your sandwich and strawberry slices you were essentially beginning the process of digestion. Second comes the job of your digestion, which is a much more time-consuming and complex process for your digestive system. It begins once you have began chewing your food. There are two known types of digestion, these include Mechanical digestion, which is when you “physically break down the food into smaller pieces”, for instance chewing a burger and having it result in several chunks, and Chemical Digestion which is when you chemically break down your food, such as eating a slice of br...
Their table had 15 mL glucose, 10 mL RO water, and 10 mL of yeast which they then placed in an incubator at 37 degrees Celsius. In conclusion, I feel that the absence of RO water in the flask made the enzymes work a little harder than when the RO water was in the mixture of the flask. Comparison #4 is between the Controlled Table and Table #5. The mixture for that table’s flask was 15 mL Sucrose, 10 mL of RO water and 10 mL of yeast, which the flask was then placed in an incubator at 37 degrees Celsius.
The human digestion system is very complex. It starts with the mouth, salivary glands, pharynx, esophagus, stomach, liver, pancreas, gallbladder, small intestine, large intestine, then ends/exits with the anus. Each step is essential to the whole system. For example, the mouth chews food and mixes it with saliva produced by the salivary glands, and then the pharynx swallows chewed food mixed with saliva, this is followed by the food traveling through the esophagus to the stomach where the food gets a bath and mixes with acids and enzymes. After the stomach, the liver, pancreas, and gallbladder produce, stores, and releases bile and bicarbonates. Bile is produced in the liver and aids in digestion and absorption of fat while the gallbladder stores bile and releases it into the small intestine when needed. Following the process into the small intestine, this is where nutrients will be absorbed into the blood or lymph (most digestion occurs here). Next is the large intestine this is where water and some vitamins and minerals are absorbed. Finally, it is the end of the road, the anus. At...
Carbohydrate digestion begins in the mouth. The salivary glands release the enzyme salivary amylase, which begins to break down starches into simple sugars. Then three brush border enzymes in the small intestine break up the sugars lactose, maltose and sucrose into monosaccharides known as galactose, glucose and fructose. On to protein digestion which begins in the stomach, where HCl and pepsin break proteins into small subunits which then travel to the small intestine. The chemical digestion is continued through the small intestine by pancreatic enymes, including chymotrypsin and trypsin, each of which act on specific bonds in amino acid sequences.
