Digestion: Why The Mouth Takes Off The Digestive System

Digestion starts in mouth and it is going through several steps. Teeth which are a Mechanical digestion start tearing and crushing the food down into small pieces so that the food will smoothly run down our throat. The salivary glands are located underneath the back of our tongues and that’s what is creating our saliva. The saliva is the Chemical Digestion is helping soften the food in the mouth so it is easy to swallow. Also saliva is the first out of several chemicals that is breaking the food into smaller bits. The tongue is the muscle that works with the food and saliva to form something similar to balls that can be swallowed. Also tongue contains taste buds so that we know if the food is salt, sweet, sour or bitter. Esophangus is a simple transportation tube that is joining the throat with stomach. When swallowing we are closing a trap door in our throats called the epiglottis. By closing this trap we are preventing the food prom going to trachea and into our lungs. Also Food moves down the esophangus using muscles not gravity. Stomach is the first stop after the Esophangus. When the food gets into stomach the stomach uses chemicals to try to make the food smaller. These chemicals are called gastric juices and they include hydrochloric acid and enzymes. (Enzymes are

The oral cavity is very important when dealing with the digestive system. Digestion begins when food enters the mouth and is mechanically broken up by the chewing movements of the teeth. The tongue moves food around the mouth to be mixed with the saliva. Saliva contains digestive enzymes to break down carbohydrates and slippery lubricants to make food easier to swallow. Without a properly working oral cavity, food would be difficult to eat and digest to get the proper nutrients the body needs.

Probiotics are friendly, live bacteria that help maintain a natural balance of organisms in the intestines. Normally, the intestines have about 400 types of probiotic bacteria that serve to reduce harmful bacteria and keep the digestive system healthy. Each child (and adult) has trillions of different microbes living in him, and no two kids have the same mix of bacteria. Two of the most common categories of beneficial bacteria that naturally occur in our body are called Lactobacillus and Bifidobacterium. Whatever the benefit, it's important to note that probiotics' infection-fighting effects are only temporary. This is because the probiotics don't build up in your child's gastrointestinal system.

The mouth does both mechanical digestion and chemical digestion. Mechanically, your incisors cut food into small pieces, next your canines make the food pieces even smaller, than premolars and molars crush and grind the food, finally saliva moistens the food to a slippery mass. Saliva contains enzymes which speed the chemical reaction in the body, this part is the chemical digestion. Your mouth is the first in your digestive system.

The digestive system is composed of the mouth, pharynx, esophagus, stomach, small and large and intestine and is aided by the mouth’s salivary glands, liver, pancreas and gallbladder, which are considered the accessory organs (Tortora & Derrickson 2014). The system begins with ingestion, or the act of eating and drinking. Once the food enters the mouth, the salivary glands begin the increased enzyme production of salivary amylase in order help with the dissolving of the food and breaking down of polysaccharides into sugars (Tortora & Derrickson 2014). After a bolus has been formed, it is contracted by skeletal muscles from the pharynx to the esophagus where peristalsis contractions keep moving the mass downward until it enters the stomach. The stomach begins to prepare the bolus for digestion by a process called propulsion in which the food is churned and mixed with gastric juices until it becomes chyme, or a liquid substance able to pass through the pyloric sphincter (Marieb 1989). In the meantime, chemical digestion begins as well; parietal cells begin

One of those other parts is the mixing of food with saliva. Saliva contains enzymes which break down the cell walls of the food, and start breaking complex carbohydrates into simpler carbohydrates and sugars. When the food is sufficiently digested, we swallow it, and it goes through a tube called the esophagus until it reaches the stomach. A muscle just outside the stomach forces it inside, and will even work if you're upside

The mouth is where the digestion first begins as firstly the scent of the food will travel to the nose causing the salivary glands in the mouth to produce saliva as there are three pairs that do this. As you are chewing the food with your teeth the food starts to get broken down more saliva is produced along with the breaking down. The secretion will be transferred into the mouth and the tongue as the salivary glands are causing it to do this. Also, the digestive juice contains an enzyme which is known as salivary amylase which now begins the digestion of carbohydrates as well as lubricating the mouth in order to help with the bolus formation.

Human digestion starts in the mouth. A human chews food with 32 teeth, which have flat surfaces for grinding and breaking down food. Enzymes contained in the saliva contribute to this breakdown of the food, which is being digested before it reaches the stomach.

Firstly the food enters the digestive system via the mouth or oral cavity which is mucous membrane lined. In this process the food begins to break down due to the salvia in the mouth which contains mucus, a very effective lubricant that coats the food to help with swallowing. Before it is swallowed the food is also broken down by the teeth which are the incisors which cut food with their sharp thin edges, the canines which are responsible for holding and grasping food which have a pointed edge and they are very strong and stable teeth and behind the canines are the premolars which are designed to hold and grasp food like the canines but they also function to crush food. The teeth farthest back in the mouth are the molars and they are used to grind food. Once the food is swallowed it travels down the oesophagus where the muscles contract with a wave motion known as peristalsis.

The digestive system includes the organs involved in breaking down food we eat. When food enters the mouth, chewing begins this is the first steps for digestion to take place. Swallowing allows food to enter the esophagus. It travels down to the stomach by peristalsis where acids in the stomach breaks it down to form a liquid. Absorption of nutrients begins when food enters the small intestine. The smal intestines takes in foods breaks it down in the body converts some of the nutrients, back for reabsorption into the bloodstream, then what is not broken down continues to pass to large intestine or colon in which water and salts are absorbed causing the waste products to become firmer turning into stool. This is the final stage. Once stool

Probiotics also referred as "good bacteria" are considered helpful in suppressing potentially detrimental bacteria and in strengthening the digestive tract.

The small intestine absorbs most digested food molecules, as well as water and minerals, and passes them on to other parts of the body for storage or further chemical change. Hormone and nerve regulators control the digestive process.

The stomach is located between the oesophagus and small intestine. It is in the left upper part of

Fibre is the indigestible portion of plant foods that helps move food through the digestive system. It softens stools by absorbing water. Fibres, also known as “bulk “or “roughages” can be found in whole

Fiber has been connected to improving other markers of health as well. The American Heart Association promotes the consumption of fiber due to evidence that it decreases risk for cardiovascular disease and moderately reduces LDL cholesterol (AHA, 2016). The American Diabetes Association promotes at least 25-30 g of fiber consumption per day for diabetes management because it contributes to digestive health and satiety (AHA, 2013). Consuming a diet that may be higher in CHO and therefore also high in fiber may offer additional health benefits that could be compromised if CHOs were extremely restricted.
