Gastrointestinal System: The Digestive System

Good Essays
Digestive System The digestive system is also known as the gastrointestinal system, where the mouth is connected by a series of organs all the way through the body to the anus. This article stated, “digestion is the process in which the body breaks down our food and drinks into smaller particles to feed and nourish our cells” (“Your digestive system,” 2004). This process is important for the body to use the nutrients from food towards energy, growth, cell repair, as well as our overall well-being. In order for digestion to begin food needs to be entered into the mouth or oral cavity. This is where the teeth chew the food up and the tongue meshes the food particles together into a bolus or ball along with the help of the lips, cheeks, …show more content…
Gylys and Wedding (2013, p 122) stated, “that the pharynx serves as a passageway to the respiratory and GI tract and provides a resonating chamber for speech sounds.” In order to keep the respiratory tract free from food particles that pass into the esophagus there is a flap of connective tissue called the epiglottis that shuts the trachea off when we are swallowing to prevent choking. The trachea is the air conducting tube that connects to the lungs in order to breathe. The bolus of food is involuntarily pushed through the esophagus into the stomach by peristaltic contractions made by the muscles. The esophageal sphincter located between the esophagus and stomach acts as a regulator for what flows into the …show more content…
The major function of the large intestine is to absorb water and vitamins from the remaining indigestible food matter and transmit the useless waste material to the rectum. The large intestine can be separated into three different sections: the ascending colon, transverse colon, and the descending colon. The descending colon is connected to an S-shape figure known as the sigmoid colon and finally connected to the straightened canal of the rectum. The rectum function is to receive the stool from colon and hold there until it needs to be transferred out. The final step of the digestive system consists of the anus, where the stool is finally released from the

    Stomach When the chewed food has passed from the mouth the esophagus, it reaches the stomach where enzymes peruse the process of breaking down the food into usable substances and forms. The braking down is achieved through stomach acid which is released from the cell lining of the stomach, along with powerful enzymes which help to further break down the food. 4. Small Intestine The contents from the stomach reach the small intestine once they have been sufficiently processed. The small intestine is a long muscular tube that releases enzymes to further break down the molecules.…

    First step is ingested food is taken into the mouth where it is torn into smaller physical parts by the teeth. The salivary enzymes; amylase and lipase are activated beginning the chemical breakdown of food. Salivary amylase divides starch into smaller glucose molecules. Physically the saliva hydrates and compacts the food for ideal propulsion through the pharynx and esophagus. Propulsion is activated voluntarily when we swallow; the tongue moves towards the hard palate of the mouth thus pushing the food into the pharynx.…

    The food is taken into the digestive system by the mouth. The mouth itself contains many organs, such as the teeth, the tongue, and the salivary glands. When food enters the mouth it must first be broken down by the enzymes inside your mouth. These organs are all working together to help digest the food into smaller pieces. The teeth role is to helps the process of chewing, chewing the food into tiny molecules.…

    Amazingly the enzymes are not active until they pass into the bowel. If it were activated any sooner it would digest the pancreas. The functions described are very important to the overall function of the body. “The pancreas make a number of different enzymes to break down bile. The main enzymes are called amylase, they break down carbohydrates.…

    The two sphincters regulate how much goes in and out 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.…

    The organs that are involved in the digestive system include the mouth, oesophagus, stomach, small intestine, pancreas and liver (Fig 3). As food enters the mouth, the food is broken down by the method of chewing. Once the food is broken down it is swallowed and moves down the oesophagus at a slow pace. Afterwards the broken-down food enters the stomach where it is broken down even more by stomach acids. The upper muscle in the stomach relaxes to let food enter and lower muscle mixes the food with digestive juices.…

    How long does the food remain in each segment of the digestive tract and what physiological processing takes place during this time? • Chemical and mechanical digestion begins in the oral cavity. Temperature, taste, texture are sensed, and the saliva helps the chemical digestion because it is secreted by the salivary glands. The breakdown of the enzymes in the saliva helps the food to be swallowed. The mechanical breakdown of the food is from the teeth, and when the food is swallowed, the pharynx is where the food is passed.…

    Segmentation (the sloshing motion that mixes chyme with the enzymes and chemical fluids in the small intestine) and pendular movement (a constrictive wave that involves forward and reverse movements and enhances nutrient absorption) will be the main contributors to mechanical digestion in the small intestine. The liver, gallbladder, and pancreas secrete enzymes, fluids, and hormones which will help in the chemical digestion of the macronutrients into their simplest components so that they can be absorbed by the body via villi and microvilli (known as the brush border) and eventually circulated through the blood stream and lymph…

    2.1 Mechanical Digestion Mechanical digestion is the act of breaking down food into smaller pieces so that it can be processed more easily by the digestive system, an example of this is mastication (chewing), the stomach also carries out some mechanical digestion using muscular contractions to break down food. 2.2 Chemical Digestion Chemical digestion is the break down of food particles through chemical reactions, this also begins in the mouth with saliva, chemical digestion within the intra-abdominal digestive system is mainly via enzymes and hydrochloric acid. The stomach releases pepsinogen which turns into pepsin and breaks down proteins, the hydrochloric acid provides a low pH level in which the enzymes can flourish. The combination of enzymes and stomach acid also help to kill any bacteria that may habe been taken in with the food. (Kent, 2000) 2.3 Enzyme Table Enzymes are important molecules, they are particularly important in digestion as they help break…
