Digestion

Normal pathophysiology of gastric acid stimulation and production. Normally the stomach holds around 50cc of fluid. There are several stimuli that work together in the complex process of the digestion process (Huether & McCance, 2012). There are three phases of gastric secretion, first being the cephalic phase, which is stimulated by the thoughts , smells and taste of food. Stimulation releases acetylcholine and the release of gastrin-releasing peptide, thus indirectly stimulates hydrogen ions.…

Digestion of a cheese burger? Step 1. When you chew, saliva is added. In addition to being a liquid which moistens, softens and lubricate food, saliva contains enzyme called amylase, which breaks down starch. In the mouth the Meat patty and the bread could be broken down and digested. Step 2. The oesophagus has two layers. Its interior is lined with cells that are packed very closely together creating a smooth surface. The circular muscle around the outside of the oesophagus is also smooth…

goes on a long journey through the digestive system and eventually is turned into waste after passing through the 6 primary organs of the digestive tract: the mouth, oesophagus, stomach, small intestine, large intestine and anus. The process of digestion starts when Bob the pizza is placed in the mouth. The main structures of the mouth are the teeth, tongue, salivary duct and oesophagus. Bob is killed, being chewed on by the teeth, enclosed in a dark area where he can’t escape. After Bob is…

stomach breaks food in our stomach calling it conit the pyloric sphiincter enters into the duodenum are small itestine that are the major part of the digest system call jejunum and the lleum into the liver then our pancreas,duodenonum makes up our digestion system our walls is cover up with ellie the structure carry the lacteal and the capillary to pick up yhe digestin nutrients npw our nutrients tranport to are blod cells are in are body.…

Abstract The purpose of this experiment was for the researcher to study one of the process of digestion which is absorption, and seeing if starch and glucose could diffuse through the dialysis tubing, and could the two be absorbed by the small intestines, and if so or not, why? To begin, in this experiment, the researchers gathered different solutions, such as, starch and glucose, filling half of each mixtures in a single dialysis tube. The researchers carefully then rinsed and pat dry the…

Chemical Aspects of Digestion Lab Report By Abdulelah Almutairi Animal Form and Function Lab, 03, 12:30 PM Instructor: Melanie Gustafso-Ropski – Lab Assistant: Corinna Monday March 9,2015 1. Part A • The enzyme used in this experiment is pancreatic lipase. The substrate for pancreatic lipase is lipids or triglycerides. Hydrolysis of triglycerides occurs in the duodenum and the PH rages are from 7.1 to 8.2. • Phenol red was used as a PH indicator of the samples.…

Methane is the final product of Anaerobic Digestion. A mixture of methane and carbon dioxide is called a biogas and it can be used for heating and can be used as a natural gas. Anaerobic treatment systems are divided into “high rate” systems involving biomass retention and “low rate” systems without biomass retention. High rate systems are characterized by a relatively short hydraulic retention time but long sludge retention time and can be used to treat many types of wastewater. Low rate…

impede the process of digestion of food. What dietary changes would facilitate food intake for those with oral cavity problems? A common problem that may impede this process is hyposalivation. This may occur for many different reasons, including dehydration and use of certain medications (Division of Oral Medicine and Dentistry, n.d. para. 3). One result of hyposalivation is a reduced output of enzymes and hence a lack of hydrolysis. This spiraling issue may inhibit the digestion of…

of the stomach. What mechanical and chemical digestion occurs in the stomach? The muscles in the stomach act as a mixer and grinder of the food. This is the mechanical part of the digestion. The chemical digestion occurs when the acids are excreted from the lining of the stomach to break down the proteins. 3. Small Intestine and Large Intestine What are the three sections of the small intestine and what role does each section play in digestion or…

The experimental design for our project was to simulate the digestion of carbohydrates, lipids, and proteins. Using a certain medication called pancreatin we tested its effects on how it was able to break down these macromolecules. pancreatin is a mixture of pancreatic enzymes that help to aid in digestion; the enzymes that are present in this mixture include amylase (breaks down carbohydrates), lipase(breaks down lipids), and protease (breaks down proteins). We had set up trials for these…
