As I look at the ham sandwich sitting on the plate before me, I start to feel queasy with disgust. The slab of ham is laced with fat. The white solid stuff is just sitting there, taunting me. Daring me to eat it. The bread is stale, crumbling, falling apart. I know that as soon as I pick up the sandwich, the bread is going to disintegrate in my fingers, leaving me with nothing but the malicious ham. No, I think to myself. I will not eat this sandwich.
I just cannot bring myself to put this, this thing into my mouth. I know that if I make myself, I will only get it into my stomach, and then it would come right back up. I stand up and walk over to my kitchen sink. I open the cupboard door that is beneath, and I dump my sandwich into the garbage can. Now, I think to myself, what to do about lunch.
I walk over to the refrigerator and open the door. My eyes start scanning the shelves. Hmmm, no…no…yes! I will make myself a turkey sandwich. I like turkey. I like turkey a lot.
I take the turkey and set it on the counter. Then I grab the Buttermilk White bread, freshly made by my mom. She’s like Martha Stewart, you know. She grows the wheat herself. She uses some kind of mill we have in the back yard to grind it into flour. We have a cow. She milked it herself. Then she made the buttermilk to put into the bread. Anyway, that’s off the subject.
I take out two slices of bread and put them onto a wooden cutting board. I put a few thin slices of turkey onto one piece of bread. I then take the other piece and gently nestle it on top of the turkey. I put the sandwich onto a paper plate and take it to the table. I look at it and think to myself, job well done. But I can’t help thinking that I’m missing something. Oh yes! Miracle Whip.
I quickly jump up and run over to the refrigerator. You see, I’m very hungry by this time. I grab the jar of Miracle Whip. I run over to our silverware drawer and grab a butter knife. Taking the two things over to the table, I sit down. I delicately remove the top slice of bread, and apply a thin layer of Miracle Whip. Then I put the top slice of bread on the turkey. I pick up the sandwich and am just about to take a bite. Then I remember. I’m supposed to be eating a ham sandwich for this essay. Well, considering I don’t like ham, I won’t eat it. But…this essay is supposed to be about a ham sandwich. So, we’l...

...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 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.
That was only my the first bite of my "ham" sandwich. I have the rest of the sandwich to go. But I think my digestive system is a little screwed up. For most people, the whole digestion process takes quite a few days. The food stays in their stomach for up to eight hours, the small intestine for a long time, and in the large intestine for anywhere from three to five days. For me, this whole process took a little over five minutes. Mmmm, I’m looking forward to my second bite.
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.

inches). After the initial bread information is gathered, one may commence cutting. Simply slice the entire length of the bread, but do not cut all the way through, to create a hinge effect. The entrée is then ready to be dressed.

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
It measures about 1.5m in length, and 6.5cm in diameter, wrap around the small intestine, in a shape of an arch. It is made up of caecum, colon, rectum, appendix, anal canal and anus. About 90% of water is re-absorbed here, which is one of its major function. There are also bacteria in the large intestine that converts protein to amino acid. These bacteria produce gas, acid and vitamin B &K by breaking down amino acid. These vitamins are absorbed here. The content of the large intestine changes to a semi solid state called faeces due to water re-absorption. (Tortora G. and Derrickson B.
Peristalsis that was mentioned earlier in the oesophagus is also used in the small intestine to help move food through and mix it with digestive secretions from the pancreas and the liver. Its first responsibility is the process to continuously breakdown, then the second and third responsibility is the absorption of nutrients into the bloodstream. As chyme moves through the small intestine, many of the molecules are absorbed in to the bloodstream and the small intestine has a very efficient way to help in this process. The inside of the small intestine has finger-like projections called villi and these raise the surface area of the gut. The contents of the small intestine begin semi-solid and then finish in a liquid form after passing through the organ. Bile enzymes, water and mucus contributes to the change in consistency. Then once the nutrients have been absorbed and any leftover food residue liquid has been passed through the small intestine, it will then move onto the large intestine through the ileocecal
Large Intestine- The large intestine is made of 3 parts; the cecum, the colon, and the rectum. Some refer to the large intestine as the colon, because the colon contains four separate parts; the ascending colon, the transverse colon, the descending colon, and the sigmoid colon (WebMD (2).) The cecum connects the small and the large intestine, acting as a transition area for food to travel. The ascending colon takes feces from the cecum to the transverse colon, during this process, bacteria digest fecal matter for the release of vitamins. The longest part of the colon, the transverse colon, is where the most absorption within the large intestine takes place. The descending colon transports feces from the transverse colon to the sigmoid colon. The descending colon walls also absorb water, nutrients, and vitamins from the feces, and can store the feces until it is read to be eliminated. The sigmoid colon can also
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.
The three parts of the small intestine, the duodenum, jejunum, and ileum extend all the way from the pylorus to the beginning of the large intestine or colon (The Digestive Sytem and Body Metabolism). The small intestine is where the majority of nutrient absorption occurs (The Digestive Sytem and Body Metabolism). Peristalsis in the small intestine mixes the food with the digestive juices from the pancreas, liver, and intestine (Diseases). Then the walls of the intestine absorb the digested nutrients into the bloodstream so that the blood can deliver the nutrients to the rest of the body (Diseases). This is the final digestion process of proteins and starches but the bacteria that are in the small intestine only produce some of the enzymes needed to digest carbs (Diseases). The remaining liquid waste is pushed from the end of the small intestine into the beginning of the large intestine, the cecum, after it is processed (The Digestive Sytem and Body
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.
Everything that cannot be broken down further goes into the large intestines and will eventually be eliminated out of the system.
“Don’t Blame the Eater” is an article by David Zinczenko that explains to Americans, specifically overweight young Americans, about the risks eating at fast food restaurants and its cause of affecting one’s health. In his article, he tries to address the issue about America’s food industries by using literal devices such as tone, logos, ethos, diction, and organization in order to spread his message. He begins his article by addressing the topic and as he continues writing, he supports his topic by writing about personal experience and moves onto the reasons why his topic in a serious issue. Although he shows an overall clear progress, he does tend to have a few problems with his writing that could be improved.
