Intestine

molecules through the oesophagus. Contractions in the oesophagus transport food into the stomach where gastric juices containing both hydrochloric acid and enzymes break down molecules further. Further contractions move the molecules to the small intestine…

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. The Mouth The digestive process begins before the cookie even enters your mouth.Once you take a bite, your teeth initiate the mechanical digestion process.Your teeth…

Digestion of a cheese burger? Step 1. When you chew, saliva is added. In addition to being a liquid which moistens, softens and lubricate food, saliva contains enzyme called amylase, which breaks down starch. In the mouth the Meat patty and the bread could be broken down and digested. Step 2. The oesophagus has two layers. Its interior is lined with cells that are packed very closely together creating a smooth surface. The circular muscle around the outside of the oesophagus is also smooth…

Eating green vegetables and fruits can keep our digestive system healthy because it contains dietary fibers and it helps to stimulate our large intestine. Doing exercise can keep our digestive system healthy because it can improve blood flow to the intestine and colon. 5.0 Disease that affect the system Gastroesphageal Reflux Disease (GERD) is a disease which affect the digestive system. Weakness of the valve between the esophagus and stomach may…

The body makes secretin when chyme enters the duodenum of the small intestines. Like others, secretin is made by special cells in the duodenum. As we have learned for some of the other hormones, secretin targets the stomach to make less enzymes and acid, and to make the mixing action slow down. More importantly, though…

Crohn’s disease is a recurrent infection that affects primarily the digestive system. It involves inflammation of the intestines both the small and the large intestines. It affects only the digestive tract of human beings. To enable one understand Crohn's disease, it is important to understand the whole digestive system and how it works in the process of digestion. The digestive system is made up of the digestive tract, the pancreases, liver and the gall bladder. Track refers to hollow organs…

In the small intestines, the pancreas and the liver contributes digestive juice which travels through a duct leading to the duodenum as well as the small intestine containing intestinal juice. The intestinal juice consists of bile, bicarbonate, and digestive enzymes. Pancreatic juice is an example of digestive enzymes that helps digests fats, carbohydrates, and proteins. The bicarbonate is used and a buffer to neutralize the acidic chyme as it enters the small intestines. Bile is secreted…

which consists of the small intestine, large intestine, and anus. Several accessory organs, such as the liver and pancreas, assist the lower GI tract with the digestion of food to release nutrients. The food is digested completely and at this time all of the nutrients have been absorbed into the bloodstream. Bacteria also assist the digestion of food and its converting into feces for defaction. There is an acidic fluid that passes from the stomach through the small intestine, consisting of…

bowel disease (IBD), of which there is no cure, only manageable treatments with possible remissions. It causes inflammation of the digestive or gastrointestinal tract (GI), although it can affect any part of the GI tract, it is mostly the small intestine. Most of the time it begins between the ages of 15-35, but can affect people of any age, men & women equally. Crohn’s was named for Burill Crohn, the American gastroenterologist who first described the disease in 1932. The exact causes of…

Abstract The purpose of this experiment was for the researcher to study one of the process of digestion which is absorption, and seeing if starch and glucose could diffuse through the dialysis tubing, and could the two be absorbed by the small intestines, and if so or not, why? To begin, in this experiment, the researchers gathered different solutions, such as, starch and glucose, filling half of each mixtures in a single dialysis tube. The researchers carefully then rinsed and pat dry the…
