mouth to the rectum. As food moves through this canal‚ it is ground and mixed with various digestive juices. Most of these juices contain digestive enzymes‚ chemicals that speed up reactions involved in the breakdown of food. The stomach and the small intestines‚ which are parts of the alimentary canal‚ each produce a digestive juice. Other digestive juices empty into the alimentary canal from the salivary glands‚ gall bladder‚ and pancreas. These organs are also part of the digestive system. Part

The Pancreas (M1) Structure of the pancreas The pancreas is an elongated digestive organ that lies next to the small intestine. Most of the pancreas is made of clusters of exocrine cells called Acini. The Acini are secretory and contain digestive enzymes which flow from the pancreas to the duodenum. Within this pancreatic tissue there are the Islets of Langerhans

Its severity depends on the region of bowel affected‚ the degree to which the lumen is occluded‚ and especially the degree which the vascular supply to the bowel wall is disturbed. Most bowel obstructions occur in the small intestine. Adhesions are the most common cause of small bowel obstruction‚ followed by hernias and neoplasms. Intestinal contents‚ fluids and gas accumulate above the intestinal obstruction. The abdominal distention and retention of fluid reduce the absorption of fluids and

that interfaces with the environment at both its origin ‚the oral cavities‚ as well as‚ at its termination‚ the anus. It is divided into different segments beginning with the oral cavity and followed by the pharynx‚ esophagus‚ stomach‚ small and large intestine‚ and the anus. There are also accessory digestive organs involved including the salivary glands‚ liver‚ pancreas‚ and gallbladder. Digestion begins in the oral cavity where the cheeks and lips press the food against the teeth‚ a process

than most of the ingested food and the end result of gastric protein digestion is a chyme of mostly polypeptides and some free amino acids to be absorbed in to the body. The Pancreatic Protease digests protein in the basic environment of the small intestine. Which pancreatic enzymes would Chloe need to break down the fats in her nutrition drink? Lipase works with bile excreted from the liver‚ and it breaks down fat molecules. Why might Chloe be at risk for gallstones (crystallized cholesterol which

“The Difference between the Human Digestive System & the Digestive System of a Cow” Digestion is the mechanical and chemical breaking down of food into smaller components‚ to a form that can be absorbed‚ for instance‚ into a blood stream. Digestion is a form of catabolism; a break-down of macro food molecules to smaller ones. Digestion begins in the mouth‚ for a cow the teeth structure is very different from humans. Instead of having two rows of sharp incisors‚ cows have a single‚ bottom row

Structures and functions of the Digestion System This essay aims to explain the structure and functions of the digestion system‚ starting from consuming a cooked dinner to chemical and physical changes within the body‚ to prepare or help absorption of vital nutrients and help disposal of waste. The structure of the digestive system starts with the gastrointestinal tract‚ it is a tube that runs from the mouth to the anus and because of this some scientist says it is an external organ; there

Include the names of vessels as you travel through them in the proper order. After‚ describe What produces bile (which cells)‚ the pathway it takes back to the GI tract‚ and its function (should include an enzyme). 3 main veins come together to form the hepatic
