Over the course of time there have been many pondering questions and theories about everyday life. Using Chemistry, the study of matter, those questions have been able to be answered. From the mixture of gases in the air we breathe to the organic substance of plastic, chemistry can be seen everywhere. However, most people misunderstand the power of chemistry in our own bodies. How is it that a simple loaf of bread, once consumed, can turn into fuel for the human body? Using the digestive system and its many organs through the process of digestion and metabolism is how our bodies receive the energy it needs to continue. Chemistry can be seen as food starts its process from entering to leaving the body, through the rate of our metabolism, and also by the transfer of energy. The chemistry in the digestive system is a very important process, because without it there would be no human life.

Compared to all other systems in the body, the digestive system is one of the most diverse and important. According to Robert Sullivan the digestive system is a set group of organs whose function is based on the process of turning food, absorbing nutrients for energy and getting rid of the bodies waste (Sullivan, 2008, p.33). The organs that are in the digestive system are the following: esophagus, stomach, small intestine, pancreas, liver, gallbladder, colon or large intestine, rectum and anus (Ballard, 2003). Imagine eating a nice dinner with delicious smelling food. Now, imagine eating the food. Have you ever wondered where your food has gone once you consume it? Through your digestive system where the mass of food undergoes a process called digestion. Digestion is the chemical and physical breakdown of food into forms such as ene...

... more. Even today more chemists are elaborating on new discoveries and important facts of the many process and reactions in the digestive system. Perhaps the latest discovery in this field would be the new diet plans that tend to speed up the process of metabolism which makes cells, including fat, break down faster resulting in a thinner waist. The digestive system is unique and different from all other systems in the body because it has many organs that each have their own important role, a specific process of where food travels, and finally multiple reactions through metabolism and other processes through ATP that convert the food we eat into fuel. Without chemistry the digestive system would fail and there would be no human life. Therefore, it is important to accept the essential role that chemistry plays not only a huge role in human life, but in all life.

Essay about The Human Digestive System - ... The advantage to this reduction in food size, all along the digestive tract, is to maximise surface area and make it easier and faster for our bodies to absorb the nutrients. Mucus also in saliva keep the mouth and upper digestive tract lubricated. As we swallow food, it passes through the mouth and starts its journey down the pharynx and is worked down the oesophagus into the stomach. A small flap of skin called the epiglottis prevents the food from entering our respiratory system by covering the entrance to the larynx, so the food has to travel down the oesophagus....   [tags: food, nutrients, pharynx, oesophagus] 776 words

Next in the line of torture it has moved past the inclosed windpipe by the epiglottis to the esophagus a long tube of darkness lined with slippery mucus. The esophagus has been using the motion of peristalsis a wave of muscle contractions that are so strong it can be done in any position to transfer food to the sphincter that leads into the stomach.The Pancreas disperses these enzymes such as amylase....   [tags: banana, died, mouth, system] 846 words

The Interesting, Complex Digestive System Essay - The human digestive system is a bodily process made up of many systems, organs and substances that break down food both physically and chemically for use by the body. But what exactly is human digestion and what happens to food as it moves through the digestive system. “…[digestion] is a group of organs working together to convert food into energy and basic nutrients to feed the entire body” (Tim Taylor). There are three major bodily mechanisms that contribute to the process of digestion. The first mechanism is the breakdown of food, the second mechanism is the process of extracting nutrients from food, and the third mechanism is excretion, or the body’s natural waste system....   [tags: body, enzymes, organs] 1538 words

The Importance of Digestive System Essay - ... The Process of the Digestive System This complicated process begins in the mouth as soon as you put the food in your mouth. Salivary amylase, which is found in saliva, starts the chemical digestion of starch by converting it from a polysaccharide to the disaccharide maltose. It functions best with a pH 6 or 7 which is slightly acidic. It then enters the pharynx and travels down the esophagus and into the stomach. The stomach is lined with strong muscular walls that contain millions of gastric glands....   [tags: foods, nutrients, waste] 1401 words

Food and The Digestive System Essay - Food is defined as a substance that can be metabolized by an organism to give energy and build tissue. The process of changing the food as the source of energy for human body is known as the digestive system. Digestive system is also important to take the food nutrient such as protein, vitamin, carbohydrate, minerals and so on. Human digestive system consists of two main digestion systems which are mechanical and chemical digestion. Human digestive system consists of seven crucial stages. The stages are mouth, pharynx and esophagus, stomach, small intestine, large intestine, rectum and lastly, rectum (refer to Figure 1 in Appendix 1)....   [tags: Metabolism, Large Intestines]

Understanding the Digestive System Essay - 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....   [tags: food, nutrition, stomach] 600 words

The Digestive System Essay - The Digestive System The digestive system is a group of organs that perform the process by which food, containing nutrients, is eaten and broken down into different components. This breakdown makes it possible for the digested material to pass through the intestinal wall into the blood stream. The digestive process contains many different steps that take place in many different organs.The first step of digestion begins at the mouth, where the food enters the mouth. Saliva is secreted from the salivary glands....   [tags: Anatomy Processes Eating Digestion Essays]

The Digestive System Essay - The Digestive System What are the main functions in digestion of the a) mouth b) stomach c) small intestine The mouth takes in the food and uses the teeth and the salivary glands do break down the food so it could move onto the next phase. The teeth chew food while the salivary glands, liver, bile duct and pancreas produce digestive juices to break down food. The stomach is a L shaped, organ situated on the left side of the abdominal cavity beneath the diaphragm. At either end of this organ is a sphincter muscle which contracts and relaxes to control the movement of food in and out of he stomach....   [tags: Papers] 696 words

Digestive System Essay - Purpose The digestive system prepares food for use by hundreds of millions of body cells. Food when eaten cannot reach cells (because it cannot pass through the intestinal walls to the bloodstream and, if it could would not be in a useful chemical state. The gut modifies food physically and chemically and disposes of unusable waste. Physical and chemical modification (digestion) depends on exocrine and endocrine secretions and controlled movement of food through the digestive tract. Mouth Mouth Food enters the digestive system via the mouth or oral cavity, mucous membrane lined....   [tags: essays research papers] 1034 words
