An Issue of Celiac Disease

Task 1 Pizza digestion starts at the mouth where it is chewed and broken down into smaller particles for easy digestion. The mouth has salivary amylase enzyme which digests the polysaccharides into disaccharides. The pizza particles are rolled into a bolus and swallowed into the stomach via the esophagus. The pizza boluses are broken down in the stomach by the gastric juice, pepsin, and several enzymes to break down the proteins. The proteins are broken down and the food […]

Rogerian Argument: Jejunocolic Bypass and Gastric Bypass

In 1963 the first Jejunocolic Bypass was performed, replacing barbaric procedures such as jaw wiring. The Jejunocolic Bypass was a type of bypass that rerouted and shortened the intestines creating weight loss by mal-absorption. Patients who had this procedure done would lose a substantial amount of weight in their first year after operation, but with complications. The complications were so severe that the procedure would be discontinued, and in 1969 the Jejunoileal Bypass was introduced. The first introduction of this […]

The Human Gut Microbiome

The human gut microbiome refers to the microbes found in the human digestive tract and their genomes. It is estimated that the number of microorganisms inhabiting the gastrointestinal tract exceeds 1014 (Bull & Plummer, 2014, pp. 17). The human gut microbiota is dominated by bacteria (Clemente et al, 2012, pp. 1259). Over 1000 species of microbes colonize the gut. The most abundant are Firmicutes, Actinobacteria and Bacteroidetes, others include Verrucomicrobia, Cyanobacteria, Proteobacteria and Fusobacteria (D’Argenio & Salvatore, 2015, pp. 98). […]
