Digestion

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…

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…

The digestion process begins when we bite into our food. We chew our food so that we can break it into smaller pieces, which make it simpler for the body to digest. The following four layers create the esophagus: the mucosa, submucosa, muscularis, and tunica adventitia. Collectively, the mucosa and submucosa build elongated folds. During digestion, the esophageal lumen is occupied with the food and liquids we swallow. However, when we are not swallowing, the elongated folds work to close…

(HCI) is a clear, highly corrosive liquid which is released in our stomach once we start consuming any food or drinks. The main role of HCI and other gastric juices is to break down the food we eat and cause the release of enzymes that further aid digestion. However, HCI has another important function; it protects our body from illness by destroying pathogens that are commonly found in foods. This ensures that we are protected from the food poisoning caused by salmonella and other harmful…

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…

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…

energy and nutrients that are needed in the body. The digestive system is made up of the alimentary canal which include the mouth or oral cavity, pharynx, esophagus, stomach, small intestines, and large intestines including the accessory organs of digestion which involve the teeth, tongue, salivary glands, liver, gall bladder and the pancreas. The alimentary canal and the accessory organs perform the following functions which include; ingestion, secretion,…

neutralizes acid chyme from the stomach. Pancreatic amylase which is digestive enzymes digests starch, trypsin digests protein, and lipase digests fat. 5. Describe the location(s) in the digestion tract where each of the major types of nutrients (Carbohydrates, Lipids, and Proteins) are broken down.…

where she could. While she did this, Ziki was being slowly churned inside her restless stomach, stewing in her digestive juices and being sloshed around as she moved. That night, the large zebra decided to take a hot bath as it usually helped her digestion. She bathed for hours, massaging her belly and relaxing in the heated water, she was still feeling quite full, even though her meal had been digesting for several hours now. That night the zebra queen went to sleep feeling relaxed and…

digestive enzymes that are released into the duodenum through the common bile duct along with bile from the gall bladder. 1 Some of the enzymes the pancreas secretes include bicarb, lipase, amylase, trypsin, and proteases all to help aid in the digestion of food as it travels through the gastrointestinal tract. Pancreatitis occurs when…
