Objectives
The purpose of this report is to make a description of the digestive tracts of pigs and sheep and also to explain briefly the process of digestion on ruminant and non-ruminant organisms. Furthermore there will be an analysis of the results that have been observed on the dissection practical. The report will be finalizing with a comparison between the digestive tract of pig and sheep.
Introduction
Digestion is the process that the food brake down into smaller components in order to be absorbed easier from an organism. During the process of digestion food passes several stages. The process of digestion include: the brake down of food in smaller components, the absorption of nutrients that food contains from the organism and on the final stage the conversion of food into feces and urine in order to be expelled from the organism. There are two different types of digestion systems in mammals. The monogastric digestive system (mono=one, gastric=stomach) and the polygastric digestive system (poly=many, gastric=stomach). Pigs and humans are examples of monogastric organism.

    The digestive systems functions are to digest food, absorb any end products that were digested (including vitamins and minerals). The physiological processes of the digestive system are ingestion, propulsion, mechanical breakdown, digestion, absorption and defecation. Mechanical digestion means to use force in order to break down food for example the use of chewing or the contraction of muscles. Chemical digestion is when the food is broken down chemically into smaller particles such as the use of the saliva in the mouth.

    Mouth- Digestion begins in the mouth. Physical actions, such as chewing, breaks food into small parts so it can be easily digested. Next, salivary glands secrete an enzyme called saliva to mix with food to start the breaking down of carbohydrates (WebMD (2).) From the mouth, food travels to the pharynx, or throat, by swallowing,

  • The Digestive System And The Digestive System

    782 Words  | 2 Pages

    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...

  • digestion of a sandwich

    574 Words  | 2 Pages

    Imagine you are eating a sandwich containing wheat bread, ham, lettuce, and Swiss cheese. Do you ever wonder where the nutrients go from all of the previous listed ingredients? Well, when a bite of this sandwich is taken, the mouth produces a saliva enzyme called amylase. This enzyme immediately goes to work by breaking down the carbohydrates that are in the bread. Once, the bite is completely chewed, the contents then are swallowed and go down the esophagus and begin to head towards the upper esophageal sphincter and the is involuntarily pushed towards the stomach. The next passage for the sandwich is to go through the lower esophageal sphincter; which transports the sandwich into the stomach.

  • Fetal Pig Dissection Essay

    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

  • White Rat Dissection Lab Report

    The first step was to obtain the White Rat and to tie it in the supine position, anterior surface facing up in side the dissection pan. To tie the animal, we used butcher’s twine and secured the front and hinds legs using a “lasso” technique, careful not touch the sharp claws. To make the first insicion I had to locate the Xifoid Process of the rat (distal aspect of the sternum). Once I had located the Xifoid Process, I had to use forceps to pull the skin of the animal’s abdomen up and use the scissors to cut. The first incision is made from stem to sternum, cutting through the errectos abdomen muscle down to the groin. The second incision ion is perpendicular to the first below the diaphragm. Because of this technique we were able to open the abdominal cavity first. The third and forth incisions were made bilaterally above the legs. The last two incisions were made in upside down “V” shape on the collarbone, to expose the thoracic cavity. This dissection was both sharp, because of the use of the scissors and scapel and blunt because of the use of the probe and forceps to move organs and skin to expose other organs not yet identified.

  • The Digestive System of the Human Body

    1624 Words  | 4 Pages

    The digestive system is very responsible for taking the whole food that people eat and turns them into energy and nutrients to allow the body to function, grow, and fix itself. The six primary processes of this system are ingestion of food, secretion of fluids and digestive enzymes, mixing and movement of food and waste throughout the body, digestion of food into small pieces, absorbing the nutrients, and the elimination of wastes. Ingestion is the first function of the digestive system, which is also known as the intake of food. The mouth is the reasoning for this process because through the mouth is the way food enters the body. The stomach and the mouth store food until your stomach is ready to digest the food that was just eaten. The reason why people can only eat a few times a day is because your body can only allow a certain amount of food depending on your body weight and type, and it cannot ingest more food than it can process at one time. The next step in Secretion, this happens in the course of the day. The digestive system secretes about 7 liters of fluid daily, but these fluids include saliva, mucus, hydrochloric acid, enzymes, and bile...
