This process converts the food into bolus. The bolus then enters the pharynx where it becomes swallowed. As the bolus passes the epiglottis (a valve-like flap that blocks the bolus from entering the lungs) it then makes it way down through the esophagus (a tube that attaches the pharynx to the stomach) and into the stomach. The minute the bolus enters the stomach it churns with acid secretions and forms into a chyme. 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.
In the mouth, stomach, and small intestine, the mucosa contains tiny glands that produce juices to help digest food. The digestive tract also contains a layer of smooth muscle that helps break down food and move it along the tract. Two “solid” digestive organs, the liver and the pancreas, produce digestive juices that reach the intestine through small tubes called ducts. The gallbladder stores the liver's digestive juices until they are needed in the intestine. Parts of the nervous and circulatory systems also play major roles in the digestive system.
A3: Mechanical digestion is the act of physically breaking down food into smaller pieces to aid with chemical digestion. Chewing is an example of mechanical digestion. Chemical digestion is the process where enzymes are introduced into the gut, where it mixes with the food there. The food is at that time, broken down to the molecular level allowing the body to absorb the nutrients for use throughout the body. A4: 1 – Amylase 2 – Lipase 3 – Pepsin 4 – Nucleases 5 – Lactase 6 – Trypsin A5: Research of experiments previously performed can be invaluable when one is looking to design their own experiments to perform.
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. This stage of digestion is where the chemical digestion begins. These enzymes can worth either on the surface or inside the epithelial lining. The ileum is the remainder of the small intestine that is used
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 small intestine comprises of the duodenum, jejunum and the ileum. Most if not all nutrients are absorbed in the stomach and small intestine. The remaining water and waste products then pass into the large intestine from where it leaves the body through the anus. The movement of food through the main digestive tubes is maintained by a series of muscular
HSC 3050 Prepare for and carry out extended feeding techniques. 1.1 Explain the anatomy and physiology of the gastro-intestinal tract in relation to extended feeding. Anatomy and Physiology Digestion of food begins in the mouth where food is chewed and softened by saliva to break down into pieces small enough for you to swallow. Food is then pushed down into the esophagus, 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.
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.
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.
