Large intestine

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…

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…

organs that work together to enable the body to digest and absorb numerous substances. It is often described as a long muscular tube starting at the mouth, and ending at the anus. The esophagus, stomach, small intestine (consisting of the duodenum, jejunum, and the ileum), and the large intestine (consisting of the cecum, ascending, transverse, and descending colon, the sigmoid, rectum, and anus), all make up the gastrointestinal tract. The esophagus is the starting point for the…

from the stomach to the small intestine. Duodenum- The duodenum connects the stomach to the small intestine. Partially digested food from the stomach gets digested in it. Bile from the liver and gallbladder,…

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…

The main job of the small intestine is to break down digested material (assimilation) with the use of chemicals in order to break down large molecules of food into little molecules and to absorb most of the nutrients from everything we eat or drink through the intestine walls via the process of diffusion. As written in IvyRose Holistic website, “Digested material may be transported into blood vessels in the wall of the small intestine by the processes of simple/passive diffusion, facilitated…

make lactase. It results from a drop in or disruption of the production of lactase in the small intestine. The small intestine is a primary part of the digestive system, and is the longest part of the gastrointestinal tract and makes up about three quarters of the digestive system. It is a hollow tube like organ that connects to the stomach one end and the large intestine on the other. The small intestine is also about fifteen to twenty feet long and one inch in diameter. It is coiled and…

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…

invaders or antigens. Antigens can be viruses, bacteria, or other foreign invaders. In normal individuals, the normal bacterial flora of the intestines is protected from the attacks from the immune system. Individuals with Inflammatory Bowel Disease these beneficial bacterial flora are mistaken as a foreign invader. Cell then travel from the blood to the intestines and cause inflammation. “When the inflammation does not subside it leads to chronic inflammation, ulceration, thickening of the…

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…
