Recommended: Chemical and physical processes on digestion
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. This essay examines the various mechanical and chemical processes involved in the breakdown of a chicken sandwich. In order for this breakdown to happen, the ‘tube’ through which the food travels requires assistance from a number of other digestive organs starting with the salivary glands, and later receiving …show more content…
Our chicken sandwich has, by now, been broken down into digestible nutrients. The pancreatic juices have broken down the carbohydrates in the bread into monosaccharides (such as glucose and galactose) which leave the enterocyte by facilitated diffusion and enter the rich network of capillaries. They are transported in the blood stream and cross into the cytoplasm by Na+ cotransporters. Amino acids are moved to the circulation by facilitated diffusion. Lipids from the butter are broken down into fatty acids by lipases and are then absorbed across the cell membrane into the cytosol where they are reassembled into lipoprotein particles called chylomicrons. These are carried through lymphatic channels and into the circulation via the thoracic duct. The bloodstream carries simple sugars, glycerol, amino acids, and a number of salts and vitamins to the liver. The lymphatic system, a network of vessels that carry white blood cells and lymph fluid throughout the body, absorbs fatty acids and
Buffalo Wild Wings was founded in 1982 by two longtime friends, Jim Disbrow and Scott Lowery. Disbrow was born in Kentucky and moved to Cincinnati Ohio, when he turned 11 so he could live with figure-skating coaches David and Rita Lowery the two later became his legal guardians. Their son Scott Lowery who was 1 when Disbrow moved in with the Lowerys, grew up regarding him as a brother. Disbrow was a rather gifted skater, so much so that he was named an alternate to the 1968 Winter Olympics in France for the United States Skating team. In 1974 Disbrow moved to Buffalo, New York. In Buffalo he got a firsthand look and taste for the cities spicy local style of chicken wings, in a place called the Anchor Bar. Later in 1981, while judging a figure skating competition at Kent State University. Disbrow ran into Lowery and the two decided to get some Buffalo-style chicken wings. After looking everywhere in town and not finding a single
Gastrointestinal tract (GIT) is the portal through which nutritive substances; vitamins, minerals and fluids enter the body. The digestive tract is more than 10 metres long from one end to the other. It is continuous starting from the mouth, passing through the pharynx and the oesophagus, to the stomach, the small and large intestines, ending in the rectum, and finally into the anus. The GI tract is divided into two main sections: the upper GI tract and the lower GI tract. Upper GIT includes the mouth, pharynx, oesophagus and stomach. The lower GI tract includes the small and large intestines and anus. The accessory organs of digestions are the gallbladder, liver and pancreas. Diseases that may occur in upper and lower GIT can be divided as oesophageal diseases, gastric diseases and intestinal diseases.
Panera Bread is a “fast-casual” restaurant that provides a variety of sandwiches, soups, smoothies, and baked goods. They are in between the typical fast food restaurants and the sit down dinning. They offer high quality, healthier products at a fast pace. They are focused on the broad differentiation strategy. They differentiate themselves from their competition in many ways. You can chose to take it to go or sit down and dine in an alluring atmosphere. Some Panera Breads have fireplaces, cozy seating, higher quality furniture and gathering rooms to make you come in and relax or come in and do some work. With an advantage to their competition, Panera has the relaxed atmosphere, quick service, healthier options, at a reasonable price that puts them above others.
The digestive system, in organisms like the mink and human, is supposed to break down the food being eaten to transfer into energy. This energy helps other functions of the body that would in turn keep it alive. The digestive system includes organs such as the stomach, intestines, liver, etc. Digestion starts at the mouth, though.
4)Stomach: The stomach squeezes and mixes food with enzymes for hours before it releases the mixture into the small intestine.
Pancreas- The pancreas creates a juice that breaks down carbohydrates, fats, and proteins. "The pancreas delivers digestive juice to the small intestine through small tubes called ducts" (NIH (5).) The pancreas is not considered part of the GI tract, but it is a necessary organ needed for the digestion and absorption of nutrients.
Chick-fil-A recognizes that their brand promise starts the minute the customer enters the premises. When a store opens for the first time, the franchised operator doesn’t just see an opportunity to sell his food product, but rather a “chance to interact, build community, and engage with customers and the community at large. We do this in a variety of ways. First and foremost, we strive to provide 2nd Mile Service to each customer. As we work to continuously improve, we want customers to experience something unique. We want to build community and create relationships between our customers and our food, people and restaurants” [3].

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.
As the digestive system breaks down your food, after it's broken down it turns into energy. Your circulatory system takes some the produced energy and transports it around the body, delivering it and other blood, nutrients, oxygen, and more compounds to every cell in your body. The digestive depends on the circulatory as much as it does vice versa because they need the blood, nutrients, and energy (broken down food) that was produced from both systems. Many digestive organs need to use about 30% of cardiac output. Both the digestive and circulatory systems get rid of unwanted or unneeded materials (waste) and feces (poop). The vial substances are absorbed by the small intestine, where it is put into the bloodstream, so it can be circulated around the body. The most important thing is that with no nutrients and circulation, there's no 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
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.
...he Buttermilk White bread. The food makes its way to the transverse colon and extra nutrients are released form the cellulose of the undigested particles. It continues on to the descending colon. There I start to manufacture vitamin K and other B-complex vitamins. Those are then absorbed into my large intestine.
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
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...
