The Digestive System Of The Human Body

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 digestive system is a group of organs working together to convert food into energy and basic nutrients to feed the whole body. To achieve the goal of providing energy and nutrients to the body, six processes take place in the digestive system.

The main functions of the digestive are taken in carbohydrates foods which enter the mouth is where it is chewed and mix with saliva which contains an enzyme called amylase. This enzyme breaks down the carbohydrates in to small molecules which are small sugars called glucose they move to the stomach. In the stomach there is enzyme which is called pepsin this enzyme is strong its function is to digest proteins when this is done the glucose goes on to the small intestine. The glucose then moves to the start of the small intestines which is called duodenum this part of the intestines function is two finish the first stage of digestion the food that comes from the stomach is mixed with enzymes that come from the pancreas and bile from the gallbladder these enzymes help to break down the glucose further. The glucose then moves into the middle part of the intestine which is called ileum this is where the glucose gets aborted into the villi which then gets the glucose into the bloodstream.

The digestive system is the process of turning food that we eat into nutrients that the body uses for energy. This system also creates waste that the body needs to eliminate. We are now going to talk about the journey of food through the digestive system to see how everything works together to reserve the nutrients of the food we take in everyday and how the body removes all the remaining substances from our body.

The digestive system consists of the gastrointestinal tract and other organs such as the liver, pancreas, and gallbladder. The GI tract has organs joined in a long tube from mouth to anus. There are hollow organs including the mouth, esophagus, stomach, small intestine, large intestine and anus. Food enters the mouth and passes to the anus through the hollow organs of the GI tract. There are also solid organs such as the liver, pancreas, and gallbladder

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

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

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.

The digestive system helps the humans break down food and turn it into nutrients. The digestive system is made up of a lot of different organs such as salivary glands, pharynx, mouth, esophagus, stomach, liver, gallbladder, small intestine, large intestine, and pancreas. Salivary glands produce saliva, which keeps the mouth and other parts of the digestive system moist. The pharynx role in the digestive system is to connect the nose and mouth to the esophagus. The mouth is used for putting in food and also eating the food. The esophagus has only one function and it is to carry food, saliva, and liquid. The stomach receives the food from the esophagus and secretes acid and enzymes that digest food. The liver regulates the composition of blood,

The digestive system has many functions that allow people to live out their daily lives including the production of energy through nutrients in a functioning digestive system. The first function of the digestive system is the ingestion process. Ingestion is the intake of food performed by the mouth. Then, the mouth and stomach are responsible for storing the food until digestion. After ingestion, the digestive system secretes fluids, in order to soften the food and protect and lubricate internal organs, through a means called secretion. The food is then sent through a procedure of mixing and movement. Mixing and movement move the food to the intestines for digestion. Digestion is the most known function of the digestive system. Food is turned into chemicals and broken down into building blocks. When the digestive system has its building blocks, absorption takes place in the small intestines. The small intestine contains microscopic blood and lymphatic cells which carry the chemicals all over the human body. Once the chemicals are dispersed, the final process of the digestive system takes place. The overall progression is called excretion. Defecation is the process within excretion. Defecation takes indigestible substances from the body, so it

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 digestive system is the body’s system of organs that provides our body absorbable nutrients and excretes waste. Our digestive system is used to process these nutrients and turn it into energy. The parts of the digestive system include the salivary glands, mouth, esophagus, stomach, liver, gallbladder, pancreas, small intestine, colon, and rectum.

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

The stomach, being the size of a smartphone, will be responsible for the storage of food so that there is enough time to properly digest larger meals (Taylor). Within the stomach, there are enzymes and hydrochloric acid that will be secreted to continue the breaking down of the food (Taylor). This breaking down of the food will disintegrate the food making it into a source of energy that will be slowly absorbed until getting into the small intestine. After the meals have been broken down, the stomach will slowly empty the substances inside into the small intestine and this process is called “chyme” (“Your Digestive System & How It works”). The small intestine, being twenty feet long in length, is divided into three parts which are the duodenum, jejunum, and ileum (Robinson). The duodenum is responsible for continuing the breaking down of the food, while both the jejunum and ileum are responsible of extracting all of the nutrients from the food (Robinson). As the food leaves the small intestine, 90% of the nutrients will be extracted to be absorbed
