Diabetes: The Step-By-Step Process

The digestive system absorbs the minerals and nutrients from the foods that have been eaten. The break down of food beings in the mouth, where the

The esophagus receives food from the mouth after swallowing and then delivers it to the stomach. The stomach holds food which it is being mixed with enzymes which continue the process of breaking down the food into a useable form. When the contents of the stomach are processed they are released into the small intestine. In the small intestine food is broken down by enzymes released from the pancreas and bile from the liver, the food is moved through and mixed with digestive secretions. The small intestine is made up of three segments the duodenum, jejunum and the ileum, the jejunum and the ileum are mainly responsible from the absorption of nutrients in to the bloodstream. These contents start out semi-solid and end in a liquid form after passing through the organ. Water, bile, enzymes and mucous change its consistency, one the nutrients have been absorbed it then moves onto the large intestine. The large intestine connects to the rectum and is specialised in processing water so that emptying the bowels is easy.

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 process of digestion first begins in the mouth by in taking food (bolus). The teeth help with masticating (chewing and breaking food particles down) allowing for swallowing and increasing surface area for chemical digestion. Enzymes found in saliva also facilitates with the chemical break down of food primarily starches and fats. The food swallowed then enters into the esophagus (a tube connecting the mouth and stomach). Peristalsis helps the esophagus to push the food in the direction of the stomach. The stomach contents are highly acidic (doesn’t affect the stomach mucosa since cells secrete mucus allowing the stomach wall to be protected) with pH levels between 1.5-2.5 allowing microorganisms to be killed, breaking down of food, and activating digestive enzymes producing a thick substance known as chyme. However, breaking down of foods further occurs in the small intestine consisting of: bile created from the liver, enzymes formed from the small intestine, and the pancreas facilitate with further digestion as well as HCI denatures (unfolds proteins) allowing them to be available to attack by digestive enzymes (also responsible in breaking down the protein). The pyloric sphincter separates the stomach from the small intestine allowing the chime to drop into the small intestine. The small intestine is the primary site for

Food is digested by being broken down, by a variety of enzymes, into useful nutrients, which are transported around the body to places where they can be of use, and into waste products, which are excreted from the body. The digestive system is made up of a number of organs, oesophagus, stomach, liver, pancreas, gallbladder, and small and large intestines, these are then separated into the digestive tract and the digestive organs. The digestive tract is, essentially, a single continuous tube that begins at the mouth and ends at the anus, in a fully grown adult it is approximately seven metres long. Food travels through the digestive tract and the digestive organs produce the enzymes and chemicals that are responsible for

Meanwhile, the salivary glands in your mouth are producing saliva, lubricating the food so it can make it’s way down your esophagus and into your stomach. Saliva contains enzymes, substances that make chemical reactions faster and that breaks down large starch molecules into smaller molecules of sugar. The first step of digestion is complete. Once your food gets to your stomach, the stomach starts to furtherly digest your food. Food in the stomach is digested chemically, with chief and parietal cells. Chief cells produce pepsin, which breaks down protein. Parietal cells produce hydrochloric acid (HCI). These cells and their products help to chemically break down food in the stomach. Once food has been mechanically and chemically digested, the food goes into the small intestine duodenum, which  is the upper section of the small intestine. Attached to the duodenum is the pancreas and gallbladder. The pancreas is an organ that produces a variety of digestive enzymes, and the gallbladder is a storage sac that holds the bile produced in the liver. Bile is a chemical that breaks down fat droplets. The duodenum is also the organ that allows nutrients and water to pass through its walls. After completing its rounds in the duodenum, your digested food makes its way down into the small intestine, and then the large intestine. Villi in the small intestines absorbs nutrients into the bloodstream. The large intestine

The small intestine continues breaking down the food and absorbs most of the nutrients. The liver and the pancreas release bile and enzymes into the small bowel to aid in this process. The small intestine joins the large intestine or large bowel, a muscular tube about five feet long. The first part of the large bowel, called the colon continues to absorb water and mineral nutrients from the food matter and serves as a storage place for waste matter. The waste matter left after this process goes into the rectum, the final 6 inches, or so of the large bowel. From there, it passes out of the body through the anus.

All cells need nutrient and energy to live and this energy provided by processes that called digestion. For example, when we eat some things like bread, meat, and vegetable, although they are delicious, but they are not forms of nourishment for the cells, therefore they need to change into an acceptable form such as smaller molecules to absorb by blood and carry to body cells. Digestion is break downing of food into appropriate form to absorb into the bloodstream. Digestion system contains the digestive tract called alimentary canal and associated glands that secrete digestive juices for digestion of food. The digestion or breakdown is started when food is taken in the mouth and mastication performed by the teeth and exposed to certain enzymes. The primary function of teeth is grasped and holds the food in the mouth cavity, they also modified to serve as a grinding mill for chewing food that mentions to mechanical digestion. With the help of the teeth, tongue, and jaw movement, food are chewed and mixed with saliva that secreted in the mouth and allowing chemical digestion to happen. The digestion of a ham, cheese, and lettuce sandwich begins in the mouth. The food in the mouth active the endocrine glands to secretion digestive enzyme that called salivary amylase. It helps to break down carbohydrates and starch. Thus, at this stage, the bread of ham and cheese sandwich chemically digested. Amylase is a starch digesting enzyme which breakdowns bread (starch) into maltose that

In the small intestine there are three segments that are called the duodenum, jejunum, and the ileum. The small intestine continues to break the food down. It does this by creating enzymes that are released by the pancreas. Bile from the liver helps in digestion of fat and it also eliminates waste. Next step in the digestion is the liver. There are also other things at work in the liver such as peristalsis. Peristalsis is when food moves through and mixes up in the digestive secretions. The functions of the duodenum is that it continues the process of breaking down food. The jejunum and ileum are responsible for the absorption of nutrients into the bloodstream. There are also three organs that have a major function in helping the stomach and small intestine to digest food. The pancreas helps digestion by releasing enzymes that the pancreas releases help break down protein, fat, and carbohydrates from what is eaten. The liver’s two main functions are to make and release bile and also to clean and purify the blood, that as came from the small intestine that is containing nutrients that was just

The saliva in the mouth starts to break down the food using saliva. When the food enterers the stomach, it is mixed with more chemicals, to quicken the break down of the food. When t has finished in the stomach, the food enterers the small intestine, where the nutrients are taken out of the food. The food then enterers the large intestine, where all the remaining nutrients can be taken out. After this stage the body excretes the remaining food.

The digestive system contains nutrients, water, and electrolytes that the body needs to maintain a healthy lifestyle. “The organs of this system ingest, and absorb food and eliminate the undigested remains as feces” (Human Anatomy and Physiology, 2012). The process of the digestive system first starts by eating food through the mouth. After the food has been eaten, it then breaks down into subunits, process called digestion. Next is the movement of the food along the GI tract so all functions can be fulfilled. Then the absorption of the nutrients in the GI tract are delivered to cells through the blood. The elimination of indigestible molecules is the last step in the process. The alimentary canal walls have four tunics (layers). “Each of these tunics has a predominant tissue type and a specific function in the digestive process” (Human Anatomy and Physiology, 2012). The mucosa is the innermost layer and is a “wet epithelial membrane abutting the alimentary canal lumen” (Human Anatomy and Physiology, 2012). The mucous membrane “consists of a surface epithelium, a lamina propia, and a muscularis mucosa” (Human Anatomy and Physiology, 2012). The

The small intestine then takes in the partially digested food and mixes it and absorbs the nutrients. Next, is the large intestine which has the job of absorbing water and adding mucus to the food. The anus is the end of the digestive tract and is where all the waste exists. The liver then produces bile which acts on the fat, the gallbladder stores the bile until it is needed. The pancreas produces insulin and digestive

The stomach is a strong muscular sac that is the mixing bowl of the body where food will be mixed with gastric acid making a liquid called chyme. Stomach muscles will continue to contract making chyme that will move to the pyloric valve, which is at the top of the small intestine, known as the duodenum. While pepsin starts the digestion of proteins and lipids begin to break apart called gastric lipase. Also very small amounts of fat-soluble molecules are absorbed through the stomach

Digestion begins when one sees food. Upon seeing food the brain sends signals for the salivary glands to release saliva. When food is first placed into the mouth by taking a bite it is masticated and broken down to increase the surface area so that food can be digested faster, as well as allowing it to be swallowed. While being masticated food is moistened with saliva, which contains Amylase, which begins the process of breaking down carbohydrates. Once thoroughly chewed saliva forms the food into a clump, which is called a bolus. Once food is chewed and formed into a bolus the tongue pushes the food to the back of the mouth into the throat so that it can be swallowed. Swallowing occurs by reflexes opening and closing the epiglottis, which

Inside your mouth is what is known as your tongue and it has the job of pushing around your food while you chew, in order to help out with the process. Once you have completely dissolved the food and are prepared to swallow what is at this point known as bolus, your tongue pushes it to the back of your throat and into the opening of your esophagus.
