Digestion

(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…

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…

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…

Body Fluids and Body Water Distribution Body Fluids What are body fluids? Body fluids, also known as bio fluids are fluids or liquids that are found and are created from the inside of animal and human bodies. These include fluids that are released by the body through excretion and secretion as well the water that is found in the human bodies. When it comes to body fluids, the majority percentage of liquid that makes up the body fluids in a person is body water. It is said that about 60% of the…

number of different mechanisms. However, this process is largely contrived through two means, parietal cells and drugs. Utilized each day in processes like digestion and metabolism, the role parietal cells and drugs play in regulating gastric acid secretion is fundamental to life. Gastric Acid Secretion by Parietal Cells Gastric acid aids digestion by creating the optimal pH for pepsin and gastric lipase and by stimulating pancreatic bicarbonate secretion. Acid secretion is initiated by food:…

Without a doubt, cellular respiration, the process of converting energy from nutrients into ATP and then releasing waste products, is important to the human body. In fact, many of our organ systems wouldn’t even be able to function if it weren’t for cellular respiration. These include the excretory, respiratory, digestive, and circulatory systems, which carry out some of the most significant actions. Additionally, the body needs mitochondria to produce ATP in order to power cells and enable them…

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,…

An enzyme is a biological catalyst; catalysts are substances that increase the rate of chemical reactions without being used up. Enzymes also make the reaction take place more often, and are needed in small amounts; they are also neither reactants nor products. Enzymes are also proteins that are folded into complex shapes that allow molecules to fit into them. The enzymes that are involved in respiration, photosynthesis and protein synthesis work within cells whereas other enzymes are secreted…

#1) A fish eats another fish. Starting in the stomach of a typical gastric fish, explain how the proteins are broken down and absorbed, as well as how the functional units are subsequently used as energy and what waste product is produced. Proteins undergo a series of steps when being digested from a full protein to amino acids. In the stomach, cells secrete pepsinogen along with H+ into the lumen. The excess of H+ ions lowers the pH of the stomach, activating pepsinogen and turning it into…
