Depending on how much food is consumed, the chyme will partially digest in the stomach and will empty out in approximately two to six hours. Once processed by the stomach, the chyme enters the small intestines. Secretions of bile come from the liver and the gallbladder (a storage place for the bile that is produced by the liver) to absorb all the vitamins, proteins, minerals, carbohydrates, and fats from the food. On the other hand, the pancreas aids the process of digestion by sending digestive enzymes to the small intestines. The left over waste, from the small intestines, transfers through the sphincter and into the large intestine.
When food enters our mouth it is moistened by saliva, salivary glands begin the digestive process from the sight and smell of food. The tongue aids in digestion by moving food around the mouth so it can be chewed property to break food down. The small intestine is 20 feet and takes 3 – 5 hours to digest food, it is dived into three sections, the duodenum, the jejunum and the ileum. It is responsible for absorbing most of the nutrients we eat in food. The small intestine breaks down most of the protein, fat, and carbohydrates we eat.
The oesophagus is a tube of muscles that contract to push the bolus down towards the stomach and this action is called peristalsis. When the food has reaches the stomach the strong walls of the stomach roll and churn the ham sandwich and add of secretions from the gastric gland. The ham sandwich now resembles a paste-like material and is called chime. The secretions of the gastric gland contain gastric protease and hydrochloric acid that further breakdown the food molecules. The small intestine is made up of three sections that help to break down food using enzymes released by the pancreas and bile from the liver.
The Digestive System The digestive system is made up of the digestive tract—a series of hollow organs joined in a long, twisting tube from the mouth to the anus—and other organs that help the body break down and absorb food. The process of digestion usually takes from 12 to 24 hours, from ingestion to elimination. Organs that make up the digestive tract are the mouth, oesophagus, stomach, small intestine, large intestine—also called the colon—rectum, and anus. Inside these hollow organs is a lining called the mucosa. In the mouth, stomach, and small intestine, the mucosa contains tiny glands that produce juices to help digest food.
oklahoma4h (2015) ptonthenet (2015) bbc.co.uk (2015) The tongue which is a muscle, works with me and saliva by pushing me around the mouth while you chew with your teeth. I am now a tiny bit of mushed-up food called a bolus when you’re ready to swallow I am pushed toward the back of your throat. Mandyparker (2015). Pharynx and oesophagus Copddysphagia (2015) Swallowing forces me through a tubular entrance which is called the pharynx this is responsible for passing me from the mouth to the oesophagus. The pharynx contains a flap-like valve called the epiglottis, this closes
CU2653 Prepare For and Carry Out Extended Feeding Techniques 1.1Anatomy and physiology of the gastro-intestinal tract: Digestion of food begins in the mouth. When you swallow, food is pushed down into the oesophagus, a muscular tube that carries food to the stomach where it is digested. From the stomach, food travels to the small intestines, where digestion continues and nutrients are absorbed into the bloodstream. 1.2 The importance of fluid and nutritional balance: Eating food provides you with nutrients that are necessary for your body to function, grow, and repair its self. We need to consume six types of nutrients to sustain life: carbohydrates, protein and fat, which all provide energy, but in different forms, vitamins and minerals,
The saliva which is contained in the mouth which is produces by the salivary glands begins to digest the food before the food is even swallowed. Saliva and the other chemicals which are produced along the way help speed up the digestive process which is called digestive enzymes. The mouth which is also known as the oral cavity is a specialized organ which receives food and breaks it into smaller pieces. The mouth is changed mechanically when biting and chewing food. In a humans mouth there are teeth and within a human they are four types of teeth which are used for different functions such as the incisor teeth are for biting and are found are the front of the mouth.
A2: 1. Mouth: The mouth starts mechanical digestion with the chewing that takes places there but also mixes amylase that is secreted from the salivary glands in with what is being chewed to start chemical digestion. (2) 2. Esophagus: The esophagus transfers food from the mouth to the stomach. (2) 3.
This tract is a series of hollow organs- the mouth, esophagus, stomach, small and large intestines. This long path extends from mouth to anus. On our tour we will concentrate on the upper gastrointestinal tract then make a left into the kidney where we will find our way to the exit out our urinary system. During eating, food passes from the mouth into the esophagus, then into the stomach from where it enters the small intestine. The small intestine comprises of the duodenum, jejunum and the ileum.
The Digestive System The digestive system is comprised of the alimentary canal and the accessory digestive organs, the digestive system breaks down food into soluble particles small enough to pass into body cells to be used for energy, growth and repair. Various chemical processes take place during digestion which enables absorption of nutrients and elimination of waste by egestion (process of eliminating undigested food from the body); the digestive process can take several hours and involves many different organs. The alimentary canal consists of the following parts: Mouth, pharynx, oesophagus, stomach, small intestine, large intestine, rectum and anal canal. The alimentary canal and the accessory digestive organs are supplied by two types of nerves, extrinsic (outside) nerves from the unconscious part of the brain or spinal cord and intrinsic (inside) nerves. Extrinsic nerves release the chemicals acetylcholine and adrenaline.
