What Happen In The Myth Of Gulp By Mary Roach

A child came up to me today and ask me if he swallows a cookie what all happens to it. Once it enters the mouth, chemical and mechanical steps work to break the cookie into smaller pieces and remove its nutrients for use by the body. Tracing the digestion of a cookie involves a quick trip down your esophagus, a churn in the stomach and a slow, winding movement through the intestines.

“Gulp”, written by Mary Roach, is a book to educate the readers about the alimentary canal. The alimentary canal is a long tube which runs from the mouth to the anus; it is a part of the digestive system. Some of the organs include the mouth, stomach, intestine, and the anus. Roach makes a point that the nose is an underrated organ in the eating process because smell is where taste begins. This leads into a discussion about chewing and the taboo and ick factor of saliva. The act of not eating a plate of food after one has spit in it boggles the mind of Roach. The enzymes in our saliva prevent us from catching a cold when we drink from an infected person and breaks down food into the digestive system. Roach fills this book with interesting characters

Swallowing is the movement of food from the mouth into the Esophagus. The esophagus secretes mucus and transports the food to the stomach via peristalsis.

In previous studies, Frank and Byram’s article suggest that taste and smell interactions are dependent on taste and odor. In their experiments, they gave subjects strawberry

Digestion starts in mouth and it is going through several steps. Teeth which are a Mechanical digestion start tearing and crushing the food down into small pieces so that the food will smoothly run down our throat. The salivary glands are located underneath the back of our tongues and that’s what is creating our saliva. The saliva is the Chemical Digestion is helping soften the food in the mouth so it is easy to swallow. Also saliva is the first out of several chemicals that is breaking the food into smaller bits. The tongue is the muscle that works with the food and saliva to form something similar to balls that can be swallowed. Also tongue contains taste buds so that we know if the food is salt, sweet, sour or bitter. Esophangus is a simple transportation tube that is joining the throat with stomach. When swallowing we are closing a trap door in our throats called the epiglottis. By closing this trap we are preventing the food prom going to trachea and into our lungs. Also Food moves down the esophangus using muscles not gravity. Stomach is the first stop after the Esophangus. When the food gets into stomach the stomach uses chemicals to try to make the food smaller. These chemicals are called gastric juices and they include hydrochloric acid and enzymes. (Enzymes are

The digestive system is also known as the alimentary canal from the mouth to the anus.

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.

Once again my mini-sub and I will be miniaturized (8 microns long) and witnessing another ‘Fantastic Voyage’ in a human body. This time I will be swallowed by George, a 55 years old man, while he is eating his meal consisting of a hamburger, French fries and a soda. I will pilot my mini-sub through George’s GI (gastrointestinal tract), which is the tube that starts with the mouth and proceeds to the esophagus, stomach, duodenum, small intestine, large intestine (or colon), rectum and, finally, the anus (Pansky, 2007). Along this pathway I will describe the digestion of George’s meal and the major structures that I will encounter. Arrived to the distal

Trace and discuss the complete movement of a bolus of food entering and exiting the human via the digestive system.

Gulp: Adventures on the Alimentary Canal by Mary Roach is a truly fascinating novel that explores the body’s digestive system, beginning at the nose and ending with the rectum. Roach encaptures the reader with a not-so encapturing topic, and throughout the book uses humor and startling facts to keep the reader engaged. Gulp is not only about the human digestive system, but humans as people as well. Roach dives into cultural differences, provides interesting historical facts, and explores scientific investigations all while informing the reader on the human digestive system.

Thirty seconds ago I was in my blueberry bush as a blueberry enjoying the sun, but now I am in the mouth of the human, in the process of being digested. The enzymes in the saliva started to chemically digest me, at the same time I was being mechanically torn and crushed by all thirty two teeth. Teeth are used to break down large pieces of food into smaller pieces so it is easier to digest. I was now going down pharynx and moving my way into the oesophagus. I saw the epiglottis close up as I was being pushed down, in a way called peristalsis. Peristalsis is the contraction and relaxing of muscles which push food. I continue my way down the oesophagus and find myself in contact with the gastric juices found in the stomach. The gastric juices

McKinley’s gulp could probably be heard by everyone inside the courtroom. For the first time, Conor felt nervous and wanted to bolt from Walter’s grip. His eyes tried to read Rearin’s expression, as his mind thought.

Hello, I’m a sandwich (or, at least I used to be one), and I have recently been eaten and digested. First, I was ingested and mechanically digested in the mouth. The maxilla on top and the mandible on the bottom worked to chew me up into smaller pieces. Amylase started to chemically digest my polysaccharides. It also told me that it was from the salivary glands. I was then pushed back by the tongue, went through the oral and laryngeal pharynx, and was pushed down by the muscular esophagus through peristalsis. I entered the body of the stomach where gastric acid chemically digested more of my polysaccharides and proteins. The gastric acid told me it was made of hydrochloric acid and enzymes like pepsin. It also told me it came from the gastric

Inside your mouth is what is known as your tongue and it has the job of pushing around your food while you chew, in order to help out with the process. Once you have completely dissolved the food and are prepared to swallow what is at this point known as bolus, your tongue pushes it to the back of your throat and into the opening of your esophagus.
