Stomach cancer

1. What enzyme in the infant is lacking? Explain your answer The lacking enzyme in the infant is glucose-6 phosphatase. When blood glucose is low, glycogen breakdown in liver produce glucose-6-phosphate. G6P release glucose into blood using glucose-6-phosphatase enzyme. This patient is lacking this enzyme so the blood glucose level is low. 2. What is the metabolic reason for elevated levels of blood lactate in this patient? What are the biochemical sources of lactate? Because of the deficiency…

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…

breaks down carbohydrates (Taylor). This chewed food then enters the esophagus which pushes it down through a process called peristalsis, in which the walls of the esophagus contract to perform movement similar to kneading. The food then enters the stomach which…

sores anywhere along the alimentary tract. Oral sores in the mouth or pharynx, along the esophagus can also happen in the rectal area. These lesions greatly compound anorexia because eating is very uncomfortable. Some medicines used to treat childhood cancer can have the neurotoxic effects of the extreme inability to have a bowel movement and jaw pain. Administration of opioid pain-relieving drugs can increase the inability to have a bowel movement. Nerve-related problems such as foot drop and…

viscous substance into a smooth liquid. Ingestion proceeds with the action of swallowing which transfers the liquid from the mouth through the throat and into the esophagus. Peristalsis begins and guides the liquid into the stomach by a downward contracting motion. The stomach is another major compartment of saccharide modification where amylases, secreted by the pancreas, further break down complex sugars to produce glucose, fructose, galactose and mannose. Absorption takes place when the…

into feces for defaction. There is an acidic fluid that passes from the stomach through the small intestine, consisting of gastric juices and partly digested food called Chyme. This acidic, Chyme reaches the lower GI tract through the pyloric sphincter of the stomach. Chyme passes through the pyloric sphincter and enters the duodenum. The duodenum is apart of the small intestine and is located inferior to the right of the stomach. Absorptions of nutrients also takes place in the walls of the…

The digestive system is one of the systems in the human body. Playing a role to maintain homeostasis, it is also known as the Gastrointestinal System. The Essay will inform; the functions and structure of the digestive system, a system that the digestive system is dependent too, how the nervous system and endocrine system control with the digestive system, advanced technology and diseases that such advanced technology can be used to cure. The digestive system has two main functions; nutrients…

As evolution of digestion has occurred, the ways organisms gain their energy from food has also evolved into much more complex processes. From the intracellular digestion process of single-celled organisms to multicellular organisms, such as humans, morphing into extracellular digestion, digestive systems have had to evolve with us so that our bodies allow us to easily absorb nutrients from our food. The simplest digestive system takes place in the subkingdom Protozoa, where organisms are made…

a ulcer may penetrate through all of the layer creating a hole. This is then called a perforation and becomes a emergency situation. The name of the peptic ulcer can be broken down further depending on the location. If the ulcer is located in the stomach it is then…

proteins that speed up chemical reactions without change to themselves. • Esophageal sphincter – the opening between the esophagus and he stomach that relaxes and opens to allow the bolus to travel into stomach and then closes behind it. Prevents the reflux of gastric contents. • Pyloric sphincter – a circular muscle that forms the opening between the duodenum and the stomach. It regulates the passage of food into the small intestine. 2. Mouth Digestive process starts in the…
