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.
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
•The forty five year old patient is diagnosed with the progressive cirrhosis inflaming the liver along with the parenchymal cells. The plain symptoms is manifested primarily because of the augmentation of edema internally in the lower abdomen.
Digestion have a function of breaking down all food into our body. Our body use all nutrients to help in the process been health and growth. Digestion supplied small molecules that will be absorbed into our bloodstream.
Glucose is needed to create the body’s source of energy, ATP, and is found in carbohydrates. Since heterotrophs are unable to produce the food, or glucose, they need for cellular respiration, they obtain this food by consuming autotrophs or other heterotrophs. When a carbohydrate is consumed it begins its journey by traveling through several digestive organs, including the stomach and the small intestine, where it is broken down into the glucose the body needs to create energy. An organ is composed of different tissues that have come together to function in a coordinated manner (textbook page 20, para 7). Therefore digestive organs are organs that work together to breakdown food into the nutrients needed for the organism to function. Once the carbohydrate has been broken down into glucose, through a process of absorption, it enters the blood stream and is transported to cells where it undergoes a chemical process where the glucose is converted to
The digestive system otherwise known as the gastrointestinal tract (GI tract) is a long tube which runs from the mouth to the anus. It operates to break down the food we eat from large macromolecules such as starch, proteins and fats, which can’t be easily absorbed, into readily absorbable molecules such as glucose, fatty acids and amino acids. Once broken down, these molecules can cross the cells lining the small intestine, enter into the circulatory system and be transported around the body finally being used for energy, growth and repair.
The origination of the digestive process occurs prior to the turkey sandwiches introduction in the mouth. The eyes and the nose are the beginning of the digestive process by seeing the food and smelling; this causes a response in this in the brain by nerves stimuli creating a visual and chemical sense. The visual stimulation causes the mouth to activate the salivary glands in preparation for the food. As we commencement to the consumption of a turkey sandwich, consisting of bread, turkey, lettuce, and cheese. Our eyes would see the sandwich, our nose would smell the aroma making our mouth water in anticipation of the food. With the mouthwatering the chemical digestion process has already begun with this secretion of saliva that contains the
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.
Digestion is defined as the process of transforming foods into unites for absorption. The Digestive System is a complex network of organisms that have six major processes: The digestion of food, the secretion of fluids and digestive enzymes, the mixing and movement of food and waste throughout the body, the digestion of food into smaller pieces, the absorption of nutrients, and the excretion of wastes (Inner Body (1).)

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. After the stomach, the liver, pancreas, and gallbladder produce, stores, and releases bile and bicarbonates. Bile is produced in the liver and aids in digestion and absorption of fat while the gallbladder stores bile and releases it into the small intestine when needed. Following the process into the small intestine, this is where nutrients will be absorbed into the blood or lymph (most digestion occurs here). Next is the large intestine this is where water and some vitamins and minerals are absorbed. Finally, it is the end of the road, the anus. At...
Our metabolism, “the totality of an organism’s chemical reactions”, manages energy usage and production of cells. We use energy constantly and our metabolism breaks down food through complex chemical reactions into energy our cells
The human body goes through many different reactions and processes that are necessary for humans to live. Chemical reactions by the human body are never seen with the human eye, but it is so vital that these processes are understood. Without this understanding, diseases and disorders can never be resolved or controlled. These processes may be small in size, but have a great deal of impact on the function of the human body.
There are many biological processes that take place within the human body, and each of these processes has its own role in maintaining the health and survival of the individual. The physiological process of healthy digestion, is a very important biological process that has a tremendous effect on an individual's health. During healt...
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...
The excretory system, which includes the rectum and anus helps the digestive system by getting rid of waste and the digestive system helps the excretory system by breaking down food to be eliminated from the body. Wow! The human body wouldn’t be able to work without one or the other. Anyways, I hope you enjoyed reading my journey throughout the human digestive system. I hope to write again from where my next journey from here will begin- perhaps it will be in the ocean or along Sydney Water pipes. Until next
