Small intestine

This third innermost oblique layer relates to the function of the stomach because it is the smooth muscle that is responsible for the churning function of the stomach that aids in its ability to digestive and move food from the stomach into the small intestine. The gastroesophageal junction is the junction between the esophagus and the stomach. The epithelium changes from…

from the mouth to the stomach then to the small intestine. In the mouth, some of the hard fats begin to melt as they reach body temperature. The salivary gland in the base of the tongue then releases an enzyme called lingual lipase. In the stomach, the churning causes fat with water and acid to mix. Very little of the digestion happens in the stomach because most of it happens in the small intestine. When the fat from the stomach enters the small intestine, then a hormone called cholecystokinin…

An enzyme is a biological catalyst; catalysts are substances that increase the rate of chemical reactions without being used up. Enzymes also make the reaction take place more often, and are needed in small amounts; they are also neither reactants nor products. Enzymes are also proteins that are folded into complex shapes that allow molecules to fit into them. The enzymes that are involved in respiration, photosynthesis and protein synthesis work within cells whereas other enzymes are secreted…

651-652. Moreover, the reason this is correct is due to the fact that in the mouth there is salivary amylase that digests starch to maltose. Within the small intestine, maltose is further broken down into glucose. Within the Protein digestion pepsin which is produced by the stomach digests protein to peptides and continues in the small intestine where trypsin carries out this same process. Lipids digestion end with monoglycerides (glycerol + one fatty acid) and fatty…

The digestive system is a series of hollow organs that form a long tube that extends from the mouth, through the abdominal cavity, and ends at the anus. It consists of the mouth, pharynx, esophagus, stomach, small intestine, large intestine, and accessory organs such as the salivary glands, liver, gallbladder and pancreas. The digestive tract contains food from the time it is consumed until it is either absorbed by the body or eliminated; muscular contractions of the digestive tract help to…

certain molecules. These molecules must be broken down small enough so that can enter the blood stream. In order for these foods to be broken down three separate digestions must take place. The three digestions are mechanical digestion, enzymatic digestion, and hydrochloric digestion. Mechanical digestion includes various functions in the oral cavity such as chewing, and also functions in various organs such as the stomach and intestines. The second type of digestion, chemical digestion, is…

entire system, Crohn’s Disease. Crohn’s disease is when the GI tract becomes inflamed causing swelling and irritable favors. Unfortunately, this disease places under the chronic category. Usually Crohn’s aims towards the small intestine and the first section of the large intestine but any area within the GI tract is fair game. The answer as to how Crohn’s disease developed is undiscovered. Although, “Researchers believe the following…

pear and lies above and is tipped over the urinary bladder. This is where the fetus develops, also known as the womb. The cervix is the narrow end of the uterus, which projects into the vagina. A vagina is a tube that lies at a 45 degree angle to the small in a woman’s back. The vagina is what receives the penis during sexual intercourse. It also is the birth canal (the mucosal lining lies in folds and also can fold) as well as an exit for menstrual…

The enteric nervous system (ENS) is primarily in charge of controlling most of bowel and gut movements and is a relatively new concept. The ENS is made up of multiple ganglia that function organs including: the small and large intestines, stomach, liver, gallbladder, appendix, and pancreas. Hirschsprung’s disease can result from a mutation of the ENS. Hirschsprung’s disease is a condition where the colon partially forms due to the mutant genes that have preceded it during the development of the…

the biliary system, primarily functions to receive, concentrate and store bile produced by the liver. which used to assist the breakdown and absorption of fat in the digestive system (Drake et al., 2009). When food is consumed and enters the small intestine, cholecystokinin is released which triggers the gallbladder to contract and secrete bile. The gallbladder is not essential for survival however, as the liver will instead drip bile into the duodenum during this process instead if the…
