In this lab report a number of tests and results will be discussed. Unknown labs are performed for many reasons ranging from figuring out the causative agent in a diseased patient, to knowing the correct microorganism to use when making certain foods and antibiotics. Unknown labs are a key to testing the knowledge a student has gained throughout the course.

• Peristalsis – rhythmic muscular contractions of the digestive track that move its contents along the digestive track. • Segmentation – contraction happening in the small intestine. It divide and mixes the chime (partially digested food and digestive juices) • Enzymes – 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…

In this essay both the digestive system of a shark and a human have been researched. While investigating, it has been found that there are many similarities and differences between both species of animals. To begin, sharks live in an aquatic environment surrounded by water and other aquatic animals. While humans live on dry land surrounded by multiple mammals in urban and rural areas. Sharks mostly prey on smaller fish . Some of the larger shark species feed on seals, sea lions, and other…

Constipation is usually not a dangerous condition but if someone has an impacted intestine this can cause bacteria to form therefore it ca’nnot kill you. Saliva is also brought up throughout the book and she tells us how saliva has enzymes such as amylase and ptyalin to help break down sugar and it is an innate immune response. My response to this book was that it is a really interesting book with many different topics for people who have the intentions of learning about the human body, with a…

Coeliac Disease And its effect on The Digestive System Introduction This report will examine the digestive system, its function in a healthy body and how it is affected in a patient who suffers from coeliac disease. http://www.entwellbeing.com.au/gluten-intolerance-vs-coeliac-disease/ The Digestive System…

The small intestine consists of three divisions: The duodenum is the uppermost division and the part to which the pyloric end of the stomach attaches. it is about 25 cm (10 inches) long and is shaped roughly like the letter C. The name duodenum , meaning " 12 fingerbreadths," refers to the short length of this intestinal division. The duodenum becomes jejunum at the point where the tube turns abruptly forward and downward . The jejunal portion continues for approximately the next 2.5 m (8…

Introduction Gibberellic acid(C19H22O6) was discovered back in the 1930s by Japanese plant pathologists. In the late 1800s, a disease called Bakanae, also known as the “foolish seedling” infected the rice crops in Japan, Taiwan and other Asian countries. The plants die after demonstrating extended growth patterns. Shotaro Hori, a Japanese plant pathologist, proved a type of fungus was the cause of the disease. The fungus was later named Gibberella fujikuroi. Years later in 1926, another plant…

Nutrients deficiency and higher competition for nutrients in the soil is a major problem in most ecosystems. In order to overcome this deficiency of nutrients, plants have developed symbiotic association with beneficial microbes and endophytes (Clark and Zeto 2000). Endophytic fungi have been reported to transfer soil limiting nutrients such as nitrogen and phosphorus (Govindarajulu et al. 2005; Guether et al. 2009; Behie and Bidochka 2014) to their host plant whereas fungi received…

Humans have been operating the genetic sequences of organisms for thousands of years by choosing organisms with the characteristics that are desired. Genetic manipulation, also called genetic engineering or genetic modification, is the process of removing a desired characteristic gene from a plant and transferring it to another plant through biotechnology (Study.com, n.d.). This technique has emerged and is still in use due to crop improvement, human nutrition, plants as Bio factories and basic…

food stimulate the salivary secretion (mouth), the food is chewed before its passage through the esophagus down to the stomach where mechanical and chemical digestion takes place. Pepsinogen from the chief cells helps with the digestion of protein, amylase from the saliva and pancreatic fluid helps with the digestion of carbohydrate, and a pancreatic enzyme known as lipase helps with fat digestion, but the protein digestion takes a longer time. Limited absorption takes place in the stomach, but…
