Digestion of Cheetos
It’s a typical day. After school you get home and you are starving, but you just want a snack. “What should I eat?,” you ask yourself. Then, after looking through the cabinets for a few minutes, you find Cheetos and decide to eat a few. With just the presence of those Cheetos in your sight, the digestion process begins in your 9 meter long digestive tract.
Crunch, Crunch, Crunch. As you munch on those first few Cheetos the digestion process begins in your mouth. Here, mechanical digestion begins to reduce the size of the Cheeto and mixes the food particles with saliva. The tongue helps mix and move the pieces of Cheeto throughout the mouth. The salivary glands in the mouth also contribute to the breakdown of the Cheetos in the mouth. They secrete amylase and mucus. The parotid glands begin chemical digestion on the Cheetos. It secretes a clear, watery fluid that is high in amylase. The enzyme, amylase, begins to breakdown carbohydrates into disaccharides. The other two salivary glands, the submandibular and the sublingual, secrete saliva containing mucus, which binds and lubricates the Cheeto particles for easy swallowing. Now the food has been formed into a bolus with the help of saliva, the tongue, and teeth. Next the bolus travels into the pharynx, where the epiglottis closes off the top of the trachea so no food can enter. Then it moves on to the esophagus, where peristaltic waves push the food toward the stomach. The food enters the stomach through the cardiac sphincter at the end of the esophagus.
Now the Cheetos have entered the stomach. The process of breaking down carbohydrates has already begun in the mouth and now more chemical and mechanical digestion will take place in the stomach. Once the bolus has entered the stomach, it mixes with gastric juice, starts protein digestion, and absorbs a limited amount. Here the chief cells secrete the inactive enzyme pepsinogen and the parietal calls secrete hydrochloric acid. When mixed together, they create pepsin. The pepsin works to breakdown the two grams of protein present in the Cheetos. Hormones are also present in the stomach and aid in the digestion process. The hormone, gastrin, increases the secretory activity of gastric glands. In the stomach, some salt from the Cheetos is absorbed through the wall. The Cheetos that entered the stomach has no...

...the Cheetos are used as energy along with the carbohydrates that were broken down in the mouth and small intestine. The calcium from the Cheetos helps make bones and teeth healthy and strong, and iron is used in the blood. The two grams of protein were broken down in the stomach and small intestine by different enzymes. Fats were also broken down in the small intestine and used as energy or stored for later use. The pancreas and the small intestine played large roles in the breakdown of the Cheetos.
About five hours later, you feel the need to relieve yourself. You excuse yourself from the table and go to the bathroom. The waste left over from the Cheetos is mainly made of the little fiber the Cheetos contained, water, mucus, and bacteria. The feces are released from your body through the anal canal and out the anus. After several hours of traveling through your body, the waste products of the Cheetos finally exit the digestive track. Those fifteen Cheetos, you ate at three o’clock, went through a long journey through your body and later that night, at eight o’clock, were released from your body in a completely new form lacking much of the components they had before.
Since it’s rolled in cheese and fried, which is really unhealthy, the high amount of calories makes sense. We can now conclude that burning the food didn't really make much of a difference in calories, it still shows the cheeto as high in calorie no matter how much was burned off, in this case 1.38 grams was burned. While comparing the nutritional labels of marshmallows and cheetos, the cheetos ended having the highest energy content, as predicted since the fats and carbs are higher than the marshmallows. During the experiment, we only came across a few errors. One our calorimeter did not work so we had to switch to a thermometer for the rest of the lab, our ring stand kept falling over and our lighter stopped working at one point but none of these errors affected our data.
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
In Water for Elephants, the story is told through Jacob Jankowski at two different parts in his life: twenty-three year old Jacob who is out there exploring the world and, ninety-three year old Jacob who feels like he is wasting away his life in a nursing home. Water for Elephants is Gruen’s third book, it became one of the New York Times best sellers, it’s also available in forty-four different languages and it’s now a motion picture (Sara Gruen). Throughout the novel the reader is brought through both Jacob’s happy memories and ones that he wishes he could forget which shows its impact on the reader, a sense of catharsis and its social significance.
The pancreas can be divided into two sections when studying the histology. The pancreas has exocrine and endocrine functions, each with unique cell types. The exocrine pancreas serves to secrete digestive enzymes into the duodenum. Some of the specific enzymes and secreted substances are Proteases, lipase, amylase, bicarbonate, and water (Bowen, “Exocrine Secretions”). These enzymes are used to break down protein, fat, and carbohydrates respectively. The bicarbonate simply act as an acid buffer to prevent damage of the small intestine as the stomach acid must be neutralized. The enzymes are created in acinar cells and the bicarbonate is synthesized in epithelial cells surrounding pancreatic ducts (Bowen “Exocrine
The article “From counterculture to Sixties Culture” clearly demonstrates that the hippie movement was not just founded on pure rebellion from what their parents had prescribed. The article reveals that the 60s culture was a product of many factors including the youths reaction to the Vietnam War, the outpouring of self expression on college campuses around the continent, the constantly dynamic civil rights, and especially the rejection of the counterculture by the mainstream society.
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
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).)
Try to imagine yourself, sitting at lunch, enjoying your sandwich and a few strawberries along the way. Once you are done your delicious meal, you take one last drink of orange juice and head to your next class. In a few minutes you are thinking about your upcoming visit to the mall. You've completely forgotten about that sandwich you had just ate. But it is still sitting in your stomach!! Now how does this work, how did your body absorb all that food? It all goes back to the digestive system.
Once the rabies disease shows symptoms on the victim it becomes impossible to cure because the disease has already spread through out the entire nervous system. Did Zora Neil Hurston accurately portray the rabies disease in the novel as to real life? Because in the novel Hurston did portray the symptoms accurately. In Their Eyes Were Watching God, Hurston gave Janie's husband, Tea Cake, great characteristics of having contracted the disease. Some of the characteristics that were shown in the novel were Tea Cake gagging when drinking liquids, bad headaches and the time period it took for the symptoms of rabies to finally show up.
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.
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.
The exocrine function of the pancreas is that it produces enzymes that aids in the digestion of food. There are three important enzymes that are crucial in helping with digestion. The first digestive enzyme is amylase. Amylase function is to break down carbohydrates. The amylase enzyme is made in two places: the cells in the digestive tract that produces saliva and the main one specifically found in the pancreas that are called the pancreatic amylase (Marie, Joanne; Media Demand, “What Are the Functions of Amylase, Protease and Lipase Digestive Enzymes”). The amylase in the pancreas passes through the pancreatic duct to the small intestines. This amylase in the pancreas completes the process of digestion of carbohydrates. Consequently, this leads to the production of glucose that gets absorbed into the bloodstream and gets carried throughout the body. The next enzyme that aids in digestion of food is protease. While amylase breaks down carbohydrates, protease breaks down protein. Protease breaks down protein into the building block form of amino acids. The three main proteases that it produces are: pepsin, trypsin and chymotrypsin (Marie, Joanne; Media Demand, “What Are the Functions of Amylase, Protease and Lipase Digestive Enzymes”). Pepsin does not occur in the pancreas but it is the catalysis in starting the digestion of proteins. Trypsin and chymotrypsin are the two proteases that occur in
“He ticked off a dozen attributes of the Cheetos that make the brain say more. But the one he focused on most was the puff’s uncanny ability to melt in the mouth. “It’s called vanishing caloric density,” Witherly said. “If something melts down quickly, your brain thinks that there’s no calories in it . . . you can just keep eating it
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...
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.
