Research Paper On Esophagus

The esophagus receives food from the mouth after swallowing and then delivers it to the stomach. The stomach holds food which it is being mixed with enzymes which continue the process of breaking down the food into a useable form. When the contents of the stomach are processed they are released into the small intestine. In the small intestine food is broken down by enzymes released from the pancreas and bile from the liver, the food is moved through and mixed with digestive secretions. The small intestine is made up of three segments the duodenum, jejunum and the ileum, the jejunum and the ileum are mainly responsible from the absorption of nutrients in to the bloodstream. These contents start out semi-solid and end in a liquid form after passing through the organ. Water, bile, enzymes and mucous change its consistency, one the nutrients have been absorbed it then moves onto the large intestine. The large intestine connects to the rectum and is specialised in processing water so that emptying the bowels is easy.

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.

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 of a pig is classified as monogastric or non-ruminant, which is having a stomach with only a single compartment, like humans. In addition, the digestive tract of the pig has five main parts, including the mouth, esophagus, stomach, and small and large intestines. Furthermore, the mechanical breakdown of the food begins upon the entrance of the mouth in the digestive tract. Basically, the food is grinded into smaller pieces by its teeth. Next, saliva is produced in the mouth, acting to moisten the small food particles, along with an enzyme that starts the digestion of the starch. Then, the food is pushed towards the esophagus with the help of the tongue. Primarily, the esophagus carries the food from the mouth to the stomach, being a tube, which is carried out with the help of a series of muscle contractions that push the food towards the stomach. Subsequently, after the first of the contractions, swallowing, has taken place, the cardiac valve, located at the end of the esophagus, prevents food from passing from the stomach back to the esophagus. Likewise, the stomach comes next in the digestive tract; it serves as a reaction chamber, adding chemicals to the food. Also, hydrochloric acid and enzymes help break down food into small particles of carbohydrates, protein, and fats. Additionally, some particles are absorbed into the bloodstream, from the stomach, while others cannot be absorbed by the stomach, being passed to the small intestine through the pyloric valve. Moreover, the small intestine aids

Describe peristaltic movement. Also called mixing waves pass over the stomach every 15 to 25 seconds.

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

Gulp. Your favorite food, right in front of you. Mouth watering and eyes glued to the plate. A big inhale and the smell is even better than it looks. You just cannot wait to dive in and devour it, but how does one recognize what your favorite food is by just a sniff? Or what happens after you chew and swallow that meal? Mary Roach,“America’s funniest science writer”, will take you through the gates of the digestive system and explain everything one would ever want to know and more about what happens in the depths of the alimentary canal.

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

When we eat, food travels down the esophagus and passes through a flap (the lower esophageal sphincter) to drop into the stomach. This flap is only supposed to open to allow food to pass down or gas to pass up (a burp). It can also open when we need to regurgitate (throw up). If the opens to much or does not close properly, stomach acid may splash up,

This report will discuss how esophageal cancer affects the esophagus. I will discuss how the cancer affects the normal operation of the esophagus, what causes esophageal cancer, how the cancer can be detected and how this cancer can be treated, I will conclude with a discussion of how common esophageal cancer is.

According to Chabner, 2017, p. 145), “lower esophageal sphincter (LES) relaxes and shrinks and move food from the esophagus into the stomach.” Therefore, Acasia hyounggi (2010), mentions that the stomach mixes with complex nutrients and gastric juice to soup for digesting. After saving soup, it sends to duodenal. Then, absorb the first quarter settlement of alcohol in 30 minutes and dismantles protein and

As soon as you swallow, this little epiglottis flops down and blocks the windpipe and the larynx. It closes it off like the lid of a trash can so that food has only one choice and that is to go down the esophagus. Now the opposite is true when we're not eating or we're not swallowing, and we're trying to breathe, the epiglottis opens up and this will allow air to pass into our respiratory tract. Now whenever food does get into our respiratory tract, sometimes if we're eating too fast and we're not giving ourselves time to swallow, then food can get lodged down in the larynx or trachea and what happens usually is we begin to cough. Coughing is basically just pushing a big puff of air through the respiratory tract, which will hopefully pop out or dislodge that food particle.

In a way, the esophagus is kind of like a stretchy and muscular highway that is about 10 inches long but rather than transporting people from destination to destination it transports food from the back of your throat and into your stomach. Besides your esophagus, also located at the back of your throat is what is known as your windpipe, which is connected to your lungs and allows air to enter and leave your body. When you swallow a small bit of bolus, a special
