Essophagus Analysis

2. Name the structure that is a double fold of peritoneum and holds the colon to the abdominal wall.

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.

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

1. Describe the anatomic location of the pancreas relative to the other organs in the upper portion of the abdominal cavity. - The pancreas is about 6 inches long and sits across the back of the abdomen, behind the stomach and liver, leveled with the top of the small intestine and it also borders the liver, spleen and kidneys. The head of the pancreas is on the right side of the abdomen and is connected to the duodenum (the first section of the small intestine) through a small tube called the pancreatic duct. The narrow end of the pancreas, called the tail, extends to the left side of the body.

1. The general anatomical features of the alimentary canal are listed below. Fill in the table to complete the information.

Colon and rectum are both located in the digestive system. There are two parts of the digestive system. Upper part of the digestive system included stomach and small intestine, in which their job is to digest food for energy. Lower part of the digestive system are called gastrointestinal system, where colon and rectum are located. Its function is to absorb fluid to form solid waste then passes from the body as a stool. Small intestine made up of the most part of the digestive system, it is about 20 feet long. It break down the foods and absorb most of the nutrients. Then it pass to the large intestine which is mainly made up of a muscular tube, colon, and it is about 5 feet long. The colon can be divided into 4 section. Ascending colon, it is the beginning of the colon that included the cecum, where the appendix attaches to the colon. Transverse colon, the second section of the colon. It located in the upper abdomen and from the right to the left. The next section is called descending colon, the lower abdomen and from the left to right. The last section,

Response: The epigastric region is of the abdominals that is superior to the transverse colon. It goes up to just about the xiphoid process of the sternum. The width of a person’s neck is the approximate width of the epigastric region, so if someone were to draw two lines starting at both ear lobes going straight down the body and then draw a line horizontally that would line the top of the transverse colon and another line that would horizontally line up with the xiphoid process, that square made would be the epigastric region. The organs associated with digestion located in that region are the liver, gallbladder, stomach, and pancreas.

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

The peritoneum is a membrane located in the ventral body cavity. It surrounds the abdominal digestive viscera. The three structures of the peritoneum include the mesentery, the greater omentum and the lesser omentum. When the peritonemeum is inflamed this is called peritonitis.

Duodenum is the first section of the small intestine, this is where the first part of digestion is completed. Food is mixed with bile and enzymes both of which help break down the food. Jejunum is where the foods nutrients are absorbed.

Consist of oral cavity, esophagus, gallbladder, liver, stomach, duodenum, pancreas, colon, cecum, appendix, jejunum, and rectum.

In between the esophagus and stomach there is a valve called the LES valve. The

Firstly, in hopes of understanding what esophageal cancer is, one must first understand what the esophagus is. The esophagus is a muscular tube connecting your throat to your stomach. It’s primary purpose it to transport food to the stomach and is usually between 10 – 13 inches long. Furthermore, the esophagus is lined with smooth muscle tissue, which causes contracts without conscious thought, moving the food along to the

The Liver the largest and heaviest organ makes bile then stores it in the gallbladder. Which stores the bile then squirts it into the small intestine to break down fatty foods if needed. Banana squeezes through the Duendom the beginning part of the small intestine connecting the small intestine to the stomach. The small intestine is a 600cm long tube, and does the most absorption in the whole digestive system through little finger like sponges called villi. Villi have capillaries located through them that absorb nutrients then leak the nutrients into the bloodstream. The nutrients are leaked into the bloodstream because cells need nutrients to be able to do their jobs for the body. Nutrients and

Colon is located in the digestive system. There are two parts of the digestive system. Upper part of the digestive system included stomach and small intestine, in which their job is to digest food for energy. Lower part of the digestive system are called gastrointestinal system, where colon and rectum are located. Its function is to absorb fluid to form
