Try to imagine yourself, sitting at lunch, enjoying your sandwich and a few strawberries along the

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

Research: When we chew something, we break down the piece we are chewing into smaller pieces, making what we are chewing easier to digest. The longer we chew, the more enzymes in our saliva breaks down our food. Chewing is an important part of digestion, and it's important to chew your food thoroughly. According

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.

Swallowing is the movement of food from the mouth into the Esophagus. The esophagus secretes mucus and transports the food to the stomach via peristalsis.

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

Trace and discuss the complete movement of a bolus of food entering and exiting the human via the digestive system.

There aren’t many compartments the food has to travel through. Food travels down the esophagus into the stomach, where it is met by stomach acid and food is broken down and passed through the small and large intestine, nutrients are absorbed, and the waste is

As you can see, it is a tubelike structure made of muscle and lined with mucous membrane. The pharynx functions as part of the respiratory and digestive system because it is located behind the nasal cavities and the mouth. It is the structure that we refer to as the throat. It is about twelve and a half centimeters long and consists of three parts; the nasopharynx, oropharynx and the laryngopharynx. (Anatomy.tv, n.d.) The esophagus branches off of the pharynx which carries food to the stomach. Swallowing takes place in the pharynx partly as a reflex and partly under voluntary control. The tongue and soft palate pushes food into the pharynx, which closes off the trachea. The food then enters the esophagus. The esophagus is a muscular tube extending from the pharynx to the stomach. . (Mohan, 2010). It is about 25 centimeters long. The production of mucus by glands in the mucosal lining as you can see lubricates the tube to permit easier passage of food moving toward the stomach. (Thibodeau & Patton, 2008). Food is pushed through the esophagus and into the stomach by a series of contractions called peristalsis. The lower esophageal sphincter is just before the opening to the stomach. It opens to let food pass into the stomach and closes to keep it there. (Mohan, 2010).

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 digestive system is the process that involves the mouth, esophagus, stomach, small intestine, large intestine and rectum. For the body to function, the body`s cells needs energy and that energy will come from the food we eat. All the food we eat contains nutrients, carbohydrates, glucose, lipids, protein and many more other substances. The only way the body can absorb and convert these nutrients into energy to our cells is through breaking down the large molecules into smaller pieces and moist by the action of enzymes.

I chose the oral cavity to describe for this discussion board. The oral cavity ingests, chews, and swallows the food so that it may enter our bodies. The oral cavity is the place where digestion begins. Before it goes anywhere in the body it has to enter our mouths first so that it may be mechanically broken down with the help of our teeth and saliva. Saliva contains digestive enzymes that help break down the food particles so that it's easier for us to swallow. Hanging at the back of the throat is the uvula which is there to serve for more than one purpose. The first purpose being it has a role in speech production, and the second one being the gag reflex. The reflex is stimulated when food enters the throat without swallowing. This prevents

We start with the mouth, in the feature, I am chewing on a bit of bread from a sandwich, the sandwich softens up two distinct ways, mechanical and concoction absorption. Mechanically, teeth are utilized to bite sustenance into little pieces and blend it with salivation with the tongue's assistance. The tongue then sends this pounded up sandwich down the throat to the stomach. Synthetically, Salivary organs in the mouth produce spit, containing the protein amylase to separate starch, is blended with sustenance, making it gentler and smoother prepared for its adventure down to the stomach.

Digestion starts in the mouth. Chewing mechanically breaks down the food with saliva. Saliva moistens the food and is an essential enzyme for the digestion of starch. Saliva contains ptyalin, which is capable of breaking down starch into simpler sugars such as maltose and dextrin that can be further broken down in the small intestine. About 10-15 seconds after chewing has begun, the food bolus passes through the pharynx and in the oesophagus. When you swallow, the epiglottis closes to prevent the food from entering the respiratory system. The soft palate closes to prevent food from entering the nasal cavity.

The digestive system is very important in digesting food and breaking it down so it can be digested easily. The digestive system turns food into energy. Throughout the process there are nutrients which are absorbed. There are many things that contributed to the digestive system such as the mouth which produces saliva which helps to break down food and nutrients such as carbohydrates with the help of an enzyme called amylase. The major food groups which are called macro nutrients include carbohydrates, proteins and fats. All of these nutrients play an important role in the body. There are also many micro-nutrients which include vitamins and minerals which provide the body with health and well-being. The digestive system is made up of the mouth, which includes the teeth (the teeth are used to cut and grind food into smaller pieces, they contain blood vessels and nerves), tongue (the tongue is a muscle that has a rough surface including the taste buds), salvia glands (they produce salvia which moistens the food to make is easier to digest), the pharynx (this helps the food travel to the stomach, the pharynx also plays an important role in the respiratory system. It also contains 2 different flaps to separate the 2 functions), esophagus (this connects the pharynx to the stomach and transports chewed food to the stomach), stomach (this is a muscle that is
