Digestion

1. Introduction This illustrated report will be concentrating on the digestive system and the detail of digestion, including mechanical and chemical digestion, extracellular and intracellular digestion. It will highlight how enzymes work within the digestive system, which ones and where they are produced. It will show the importance of metabolism and its two categories anabolism and catabolism, there will also be an illustration of how nutrients are processed during anabolism and catabolism. It…

The Gastrointestinal System The gastrointestinal tract is a collection of organs that work together to enable the body to digest and absorb numerous substances. It is often described as a long muscular tube starting at the mouth, and ending at the anus. The esophagus, stomach, small intestine (consisting of the duodenum, jejunum, and the ileum), and the large intestine (consisting of the cecum, ascending, transverse, and descending colon, the sigmoid, rectum, and anus), all make up the…

The nervous system carries data to and from the brain and spinal cord to various bodily parts. There are three main functions of the nervous system, including sensory input, integration of data and motor output which occurs in the Brain and/or Spinal Cord. Sensory input is described as when the body gathers information of data, which correlates with the human senses such as touch, taste and sight. Integration of data occurs in the brain only once the brain has processed the information and is…

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…

is the first or base chakra and is located in the pelvic floor and corresponds to the coccygeal plexus of nerves. In the masculine body it lies between the urinary and excretory openings, in the form of a small dormant gland termed the perineal body (or central tendon of perineum). In the feminine body it is situated inside the posterior surface of the cervix. This chakra is considered an embryonic form of consciousness because it is primarily active from about three months in the fetal stage…

enterobacterium, koalas would not be able to utilise proteins bound to tannins which would result in the koala suffering malnutrition (R. Osawa et al, 1993a). The retention time is extremely long for the koala in the hindgut which increases the digestion of nutrients, decreases the possible loss of microbial protein through faeces and breaks down large contents of fibre which is achieved by the caecum for maximum absorption. Hence, a slow retention time is an advantage to the koala to utilise a…

the oral cavity and salivary glands. The function of the oral cavity is the ingestion of liquids, solids and the chewing of solids to break them down ready for the stomach. Salivary glands in the oral cavity secrets saliva in order to aid smoother digestion down the oesophagus and amylase starts breaking down any starch. As authors Marieb and Hoehn(2015) states the submandibular and Minor salivary glands secrete saliva, serous fluid and Mucus, but the Von Ebner’s Gland secrete a fluid which…

addition to hormonal secretion, the pancreas contributes to digestion by releasing enzymes. The pancreatic enzymes include trypsin, chymotrypsin, carboxypeptidase, amylase and lipase. Protein digestion occurs with trypsin and chymotrypsin. Amylase is a starch to disaccharides and fat digestion occurs with lipase (Lewis et al., 2014). The proteases (trypsin, chymotrypsin and carboxypeptidase) are secreted in the inactive form so digestion of the pancreas does not…

We chew our food to break it into smaller pieces, so that it is simpler for the body to digest. During digestion, the esophageal lumen is occupied with the food and liquids we swallow. However, when we are not swallowing, the elongated folds of the mucosa and submucosa work to close the lumen. There are two sphincters located within the esophagus. The sphincters maintain a circular shape, and act as a door shutting channels when appropriate (Circus, 2015). I will be focusing on the lower…

Mixing and movement • Digestion • Absorption • Excretion Inside the mouth, there are several accessory organs (teeth, salivary glands, and tongue) that aid the process of digestion. These organs breakdown…
