I am a grilled cheese sandwich, ready to be eaten, and ready to go through digestion. I am made up of bread, butter, and cheese. My bread is made up of carbohydrates and fiber. My cheese is made up of fat, mainly, but also contains a bit of protein and some vitamins and calcium. My butter is also mainly fat. I am lifted up into the mouth. I am chewed while saliva is produced to make me into a paste. The amylase enzymes turn the starch molecules found in my bread into glucose. This is used by cells to give humans energy. When swallowed I enter the throat, where muscles push me down into the esophagus which joins the throat and the stomach. I enter the stomach where hydrochloric acids break me down further. Protease enzymes break my proteins
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 food digestion plays an undeniably important role in our body system, which is the main way for the human kind to gain nutrients and energy in order to growth, repairs the body cells, and carry out the daily routine (National Institutes of Health, 2013). The foods and drinks that people consume are required to be turned into the smaller nutrient-molecules before the blood absorbs and carries the various nutrients such as carbohydrates, proteins, fats, vitamins and minerals to the body cells (National Institutes of Health, 2013). According to National Institutes of Health (2013), the decomposition of food nutrients are completed through the digestive system which form by the gastrointestinal (GI) tract, also defined as digestive tract, and along liver, pancreas and gallbladder as well. The GI tract is made up of a series of hollow organs with the connection from mouth to anus, which consisting buccal cavity (mouth), esophagus, stomach, small intestine, and large intestine. Based on Batrisya (2013), the food digestive process are classified into four stages, that are ingestion, digestion, absorption, and egestion or elimination (refer to Figure 1 in Appendix 1).
...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.
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.
What happens to food once it is ingested? Where does it go? How is it broken down into smaller pieces? The digestive process is very complex, but simple to understand. It involves several steps that include from being chewed inside the mouth, to landing in the stomach for more breakdown, traveling through the intestines, and finally exiting the body.
Personal Narrative There lay her limp body staring up at us. Her cold eyes were no longer
Leaving the bodies for last we walked down the drive to take a look. Several rifles and shotguns were leaned carefully again the big oak. Two handguns and some knives were on the grass in front of them. Four people dangled from a branch of the tree close enough to each other to bump like a weird wind chime. A young couple and the other twice their age at a guess from the gray hair and styles of dress. They were probably parents and a married son or daughter with their spouse. Other than being hung there were no injuries apparent on any of the four. From the condition of the bodies they had been dead about a day.
On the Monday October 27th, 2014, for the first time in 4 years I did not wake up at 5:30 in the morning, I was not putting on a green skivvy shirt and shorts. There was no formation, no one that was higher command I had to report to, telling me where I had to go, what time I had to eat breakfast, what was I doing this day or what our platoon plans were for the day. There were no PT (physical training) I had to do this morning. Instead, I woke up grab a regular t-shirt, khaki shorts, and my two sea bags full of clothing and gear that I collected during my time in the Marine Corps. I threw everything in my vehicle and drove from Camp Pendleton, California to Quincy, Illinois. Within two weeks I was accepted to Southern Illinois University Carbondale. For three days, I stayed at the
As I walk into Hazen and begin my high school journey I think to myself what I want to accomplish when I leave. Hazen is like the older sister I never had, someone who you hate occasionally, but look up to and pushes you to achieve your personal goals. As I walk through those Highlander doors I was immediately surrounded by the brightest minds, talent, and innovative bunch of my generation. Each one unique and each one having something special to offer, and I soon realized that I want to leave high school like I was never leaving. By making the most out of my high school experience I want to gain maturity and the satisfaction of knowing I made a difference in my school and community. By becoming a member of the National
It was me and my friend in my car. We had drove over to St Louis, Missouri during the summer. We were 9 hours away when we had decided it was time to drive back home to Des Moines.
When I was younger I was not so smart and would do questionable stuff all the time. I would jump from boulders to other boulders, climb on top of chairs, and even try killing snakes I would find in our yard. One day I learned a lesson from going on one of my self proclaimed adventures with a good friend.
My diet does not give me the proper amount of calories, carbohydrates, and protein. However, I need to reduce my fat intake. To do all this, I could probably add some different things to my salad that I have for lunch, and have less red meat. I could maybe add some chicken instead of cheese to my salad. And instead of beef for some dinners, I could replace it with either chicken, or fish. Apparently I also have to eat more calories, so instead of bigger meals, I could have some snacks throughout the day that are a bit more filling then applesauce. I also noticed that I am eating too many of the bad carbohydrates. I could replace the white breads and pastas with whole wheat or whole grain breads. I could also change the white rice to brown or wild rice.
I was running, running as fast as I possibly could. I just couldn't get away. They were after me, I knew they were. I couldn't run forever, no one can. I knew they saw everything I did, but i didn't care. I was going to hide even if they saw it or not. I got tired of looking for a place to hide and ducked into a dark alleyway. My heart was racing, my body was shaking, and I had adrenaline coursing through my entire body. I was scared, more scared than i had ever been, and that made me worry about my chosen hiding place. I checked my wristwatch and waited for the time to come. Three......two......one...., I pushed my body off the cold, hard wall and dashed to the other side of the dumpster, but i was too late. They were right there, staring at
Everyone loves a thrill. We watch movies that make us rethink what is in the dark with us, jump off of bridges and cliffs with our only savior being a bungee cord that may or may not be 10 years old, and we create gravity defying, speeding cars without motors and brakes. The crazy thing is, we do it all for fun. I, however, didn’t have a fun time when I went on a roller coaster that went upside down for the first time.
much better, so you have to keep them close and near to you. A few weeks into summer Abi and I went over to Makenzie’s house to hang. We had not seen each other in a while so we sat and talked for awhile in Makenzie’s horse themed room. Little did we know what was going to happen later that day.
