No guts, no digestion! By Shavinda Fernando Hi there. My name is Albert and this is my adventurous story of my journey through a human. I was a delicious gourmet hamburger with fresh ingredients like salad, mustard and an angus beef pattie. I was dumped into a family feed box labelled with a massive golden arched ‘M’. Now, I’m quite an intelligent burger, unlike my other food companions and I love studying about the fascinating human digestive system when I went to Burgerton College. I’m here to tell you first-hand about my digestive journey into the human body! Here is a map of the human digestive system for your convenience to pinpoint where I am in my journey as I am recounting my story. The Digestive System Diagram Mouth The human’s sweaty hands grabbed me into his mouth and his unflossed molars grinded me to pieces. The mouth was the gateway to the digestive system. It takes the food (me!) and breaks it down into tiny pieces for energy. Humans have four kinds of teeth: …show more content…
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 …show more content…

...ould make someone choke. Also, if the esophagus was not working food would get stuck causing it not to transfer food to the stomach to break it down, and it would block the windpipe so the human couldn't obtain oxygen. Another catastrophe would be if the liver wasn’t working because it would cause the gallbladder to be affected because there would be no bile, and if the gallbladder wasn’t working bile wouldn’t be released. Proteins wouldn’t be broken down without a pancreas so we need that. Also if the large intestine wasn’t doing its job waste would still be full of water making it runny, and if the rectum wasn’t working there would be no storage of waste. Lastly if the anus wasn’t working there wouldn’t be any release of waste which could cause a person to get sick. That is why all parts of the digestive system is important, and what journey it takes.
The radiolab program “Guts” the cast talk about the fascinating world that is our intestines. They begin by introducing William Beaumont an army doctor at fort mackinac, who saves Alexis Saint Martin from a gunshot wound that had left a giant hole in his stomach. Being a doctor and a scientist in 1822 Beaumont was intrigued with he had seen coming out of this hole; guts, lungs, and food. A year after the GSW the hole hadn’t gone away, Alexis had grown a fistula with just a flap of skin covering the hole. After noticing this Beaumont offers him a job, not just out of kindness but to study Alexis and his fistula. Beaumont then begins his experiments; he began by inserting different kinds of food attached to a string into the fistula and recorded
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
...ve eaten, to break down the food into a liquid mixture and to slowly empty that liquid mixture into the small intestine. Once the bolus has entered your stomach it begins to be broken down with the help of the strong muscles and gastric juices which are located in the walls of your stomach. The gastric juices are made up of hydrochloric acid, water, and mucus- and the main enzyme inside of your stomach is what is known as pepsin, which needs to be surrounded in an acidic setting in order to do its job, that is to break down protein. Once the bolus has been inside of your stomach for long enough it begins to form into a liquid called chyme, and what keeps the chyme from flowing back into our esophagus are ring shaped muscles known as sphincters located at the beginnings and ends of the stomach and they have the task of controlling the flow of solids and liquids.
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.
The waste of my "ham" sandwich keeps going. The haustra removes any excess water that was not absorbed in my small intestine. It doesn’t have to do much work, because there is hardly any area for absorption. The waste then travels down my sigmoid colon to my rectum. There the waste, now called fecal matter (A.K.A. feces) is stored until I have enough to defecate through my anal sphincter.
The digestive system is made up of several organs that all work together so that the body can get the energy it requires to go about its daily tasks. The initial way the gastrointestinal (GI) system does this is by breaking down the food we eat into smaller and smaller pieces so that the body can use the energy from the food to help repair and build new cells. The pathway that the food takes to go through the body is called the gastrointestinal tract. The GI tract is a series of organs that begins in the mouth and goes all the way to the anus, which, in adults, is about thirty feet long and takes anywhere from twenty four to seventy two hours, depending on the individuals digestive factors, for food to travel through.
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. The saliva contains enzymes such as Ptyalin, which starts sugar digestion. The enzymes also provide lubrication to help in the chewing and swallowing of the food.
The esophagus is a thick-walled muscular tube located behind the windpipe that extends through the neck and chest to the stomach. The bolus of food moves through the esophagus by peristalsis, a rhythmic series of muscular contractions that propels the bolus along. The contractions are assisted by the pull of gravity. Nucleases digest nucleic acids into nucleotides in the small intestine. Most absorption in the small intestine occurs in the jejunum.
The excretory system is a passive biological system that removes excess, unnecessary materials from the body fluids of an organism, so as to help maintain internal chemical homeostasis and prevent damage to the body. The dual function of excretory systems is the elimination of the waste products of metabolism and to drain the body of used up and broken down components in a liquid and gaseous state. In humans and other amniotes most of these substances leave the body as urine and to some degree exhalation, mammals also expel them through sweating.
The digestive system is a very important system in the human body. It is a group of organs that work together to turn food into energy and nutrients in the entire body. The food that was chewed in a humans’ mouth now passes through a long tube that is inside of the body that is known as the alimentary canal. The alimentary canal is made of the oral cavity, pharynx, esophagus, stomach, small intestines, and large intestines. Those few things are not the only important accessories of the digestive system there is also the teeth, tongue, salivary glands, liver, gallbladder, and pancreas.
As you can see, the digestive system is a very unique complex system. It is also extremely critical for the human body and each part has to work correctly in order to keep the digestive system working properly. It isn’t something we think about daily, but in reality it is something that we should be appreciative for every day. Without this system we would not have life.
