Anaerobic digestion

then to the large intestine. 2. How long does the food remain in each segment of the digestive tract and what physiological processing takes place during this time? • Chemical and mechanical digestion begins in the oral cavity. Temperature, taste, texture are sensed, and the saliva helps the chemical digestion because it is secreted by the salivary glands. The breakdown of the enzymes in the saliva helps the food to be swallowed. The mechanical breakdown of the food is from the teeth, and when…

at each station to assist any children if needed. The amount of space available is very important in keeping children safe, if too many activities are crammed into one space it could be dangerous and the risk of accidents may increase. First aiders should be available to ensure all children are kept as safe as possible and to ensure that any children who are injured get the assistance they require as soon as possible in a safe, calm and controlled way. Activity Two (2): The Age of the Children…

Meat is defined by the Oxford English Dictionary as the flesh of an animal or bird. Food is any nutritious substance that is being eaten by man, animal or absorbed by plants in order to grow and maintain life. Meat is one of the many foods consumed by man. Meat is healthy, nutritious and beneficial to the existence and survival of man. Survival of man is, therefore, reliant the availability of vitamins, minerals and the classes of food man eats. The United States Department of Agriculture…

nutrients. Without these vitamins, people on the diet will face deficiencies in things like iron, calcium, thiamine, niacin and more. Another risk of the diet is that since the amount of fiber taking in is so low, constipation and problems with digestion can be seen (Baker 2014). Acquiring to be gluten free not only changes your diet, but it also changes your vitamin levels, your digestive system, and your immune system as well. The gluten free diet takes a lot of label reading and caution when…

goes on a long journey through the digestive system and eventually is turned into waste after passing through the 6 primary organs of the digestive tract: the mouth, oesophagus, stomach, small intestine, large intestine and anus. The process of digestion starts when Bob the pizza is placed in the mouth. The main structures of the mouth are the teeth, tongue, salivary duct and oesophagus. Bob is killed, being chewed on by the teeth, enclosed in a dark area where he can’t escape. After Bob is…

website, “Digested material may be transported into blood vessels in the wall of the small intestine by the processes of simple/passive diffusion, facilitated diffusion, primary active transport, or secondary active transport.” (2016, para. 12). So digestion means the process where food and drink are broken down into very small pieces in order for the body to be able to use them sustain cells and for energy.…

Whipple Procedure Whipple procedure is a surgery to remove the head of the pancreas, the upper part of the small intestine (duodenum), and the organ that stores fluid (bile) made in the liver (gallbladder). Part of the stomach may also be removed during this procedure. The pancreas is a large gland located behind the stomach. It helps digest food and it produces hormones that regulate blood sugar. The head of the pancreas is the part that is connected to the duodenum. A Whipple procedure may…

and molars, cusps on teeth. The salivary glands produce saliva and the enzymes in the saliva contribute to the breaking down of food through chemical digestion. Similarly, the sharks mouth is composed of teeth and tongue, but sharks do not have salivary glands. Since sharks’ swallow food as a whole or as large pieces, very little mechanical digestion happens in the mouth. So, the teeth and tongue are basically useless regarding the digestive aspect of a…

Mealworms Response to Dark and Light Sujit Vankineni Introduction: Mealworms are baby versions of adult black beetles. Mealworms are also considered the larvae stage of the black beetles. The mealworm has a hard outer body called the exoskeleton which is used for burrowing. The mealworms shed their skins a few times as they grow in a process called molting. The mealworm has four stages of growth which include egg, larvae (the mealworm), pupa, and the adult (the black beetle). Mealworms enjoy…

Normal pathophysiology of gastric acid stimulation and production. Normally the stomach holds around 50cc of fluid. There are several stimuli that work together in the complex process of the digestion process (Huether & McCance, 2012). There are three phases of gastric secretion, first being the cephalic phase, which is stimulated by the thoughts , smells and taste of food. Stimulation releases acetylcholine and the release of gastrin-releasing peptide, thus indirectly stimulates hydrogen ions.…
