Task 4 - Chemical Digestion - 1880 Words

Task 4 – Chemical digestion The digestive system is the process that involves the mouth, esophagus, stomach, small intestine, large intestine and rectum. For the body to function, the body`s cells needs energy and that energy will come from the food we eat. All the food we eat contains nutrients, carbohydrates, glucose, lipids, protein and many more other substances. The only way the body can absorb and convert these nutrients into energy to our cells is through breaking down the large molecules into smaller pieces and moist by the action of enzymes. Features of each organ Mouth:-It contains the teeth, gums, soft palate, hard palate, the tongue and the lip. The soft and hard palate`s functions of prevent the large pieces to enter the body and mainly separate from trachea and esophagus. The tongue is where the saliva is mixed with enzymes and watery content to moist the food and allow the movement during mastication. The teeth breaks down food. Esophagus:- It is located inside of the trachea, near the windpipe that is responsible for the respiratory system, these two structures are separate by the epiglottis. A muscular movement that pulls the food downwards is called peristalsis. Stomach:- It has a J-shaped structure that can increase or decrease its surface area by the rugae and contain a rich quantity of digestive juice that breaks down large molecules Liver:- It is made up of two parts called lobes. The right and the left lobes are supplied by the hepatic artery andShow MoreRelatedNutrition and Digestion876 Words   |  4 Pagesenzymes? What specifically is the role of an enzyme in digestion? Enzymes are working proteins that facilitate chemical reactions without being changed in the process. Organs of the digestive system excrete digestive juices, which contain enzymes that break the bonds of nutrients that can be absorbed. 2.

Its processes include: food ingestion, enzyme secretion, digestion, absorption and defecation. Its organs form the gastrointestinal (GI) tract. Main digestive organs: Mouth (oral cavity): Beginning of the GI tract, â€Å"the roof of the mouth forms the hard palate, which leads into theRead MoreHuman Digestive System1103 Words   |  5 Pagestypes of digestion: Mechanical and chemical. The teeth carry out mechanical digestion. There are 4 types of teeth: Incisors: 8 front teeth 4 on the top and 4 on the bottom. Shaped for biting and cutting. Canines 4 teeth located on either side of the incisors. 2 on the top and 2 on the bottom. Shaped for tearing food. Pre molars: 8 located behind cuspids. 4 on the top and 4 on the bottom. Shaped for crushing food. Molars: 8 - Double rooted teeth with bumpy chewing surfaces. 4 on the top and 4 on theRead MoreEnzymes Of Health And Industry1695 Words   |  7 Pagesnot be the same. We need enzymes for almost every chemical reaction that occurs in our bodies. Many industries rely on enzymes to help in their industrial chemical processes. Without enzymes we wouldn’t have cheese, detergent, or bread. We wouldn’t be able to drink milk or digest our food. Enzymes are often a forgotten part of our daily lives, but we couldn’t live without enzymes. Enzymes are natural catalysts that play a crucial role in the chemical processes of both our health and modern industryRead MoreThe Mouth Is Where It All Begins2331 Words   |  9 Pagesresponses to food, mastication, chemical digestion, swallowing, speech, and respiration† (Saladin, p 958). The mouth has many anatomical landmarks, which include, cheeks, lips, palate, tongue, oral fissure, fauces, and squamous epithelium (Saladin, p 958). The mouth is located at the bottom center of the face, and is controlled by the mandible. 1. Digestion: Before digestion even begins, the way food is cooked breaks down macromolecules. The mouth begins digestion through mastication and use ofRead MoreEnergy Crisis and Environmental Pollution Essay example1488 Words   |  6 Pagesmicrobial fuel cell (MFC) has been introduced to directly produce electrical current from waste streams based on the ability of particular bacteria, to bio-catalyze an oxidation and/or reduction reaction at an anodic and cathodic electrode, respectively (4–6) (Figure 1).

Therefore, when the sound is heard at other time, the brain’s amygdalae will send fear-related signals upon hearing of the sound (â€Å"What Causes Fear† par 4-5). The painful experiences cause amygdalae to become more sensitive to sensory signals (images, sounds, words and situations) as well as all the details involved by the danger, which accompanied the horrors of injury, the pain of social rejection, ridiculeRead MoreTaking a Look at Polylactic Acid Polymers1509 Words   |  6 Pagessuch as the ability to transform them back into feedstock for plant material thus aiding in the reproduction of new materials; this is why it is referred to as a closed loop cycle [4].

These type of organisms require organ systems to carry out the life process. Organ systems are group of anatomical structures that work together to perform a specific function or task. These anatomical structures are found in all multicellular organisms such as worms and pigs. In these complex multicellular animals, cells are organized into tissues, tissues are organized into organs, and organs are organized into organ systems.
