Describe The Structure And Function Of The Digestive System

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 alimentary canal is where the digestive system takes place; it has different components in order for food to be thoroughly processed. The digestive system is composed of an enteric nervous system and has four layers of tissues; the mucosa, submucosa, muscularis externa, and serosa. Food enters through the mouth and passes through the esophagus, stomach, small intestine, and the large intestine before exiting the body through the anal canal. This occurs within the digestive system in four main steps; ingestion, where food enters through the mouth, digestion where food is broken down physically and chemically, absorption where nutrients are taken to their desired organ for use in the body, and elimination where waste is removed from the body due to being useless or toxic.When it comes to the human body there are plenty of components that we take for granted. Think about it, when was the last time you dwelled upon the function of your saliva or pondered on the responsibility of the esophagus? If you are like me, the answer to the question is simple, never. It is because our body is one of the greatest and yet most underappreciated machinery known to man. Within that system, which tends to get a lack of appreciation, stands alone one main process that we utilize on a daily basis and rarely give credence to its importance. This process is known as digestion, which occurs in the alimentary canal also known as the digestive system. The digestive system consists of 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.

What are the three sections of the large intestine and what roles does each play in digestion or absorption?

Once again we have been miniaturized in the submarine to continue the fantastic voyage of the digestive system. We will be touring a 55-year-old male. The host will be having a hamburger, French fries, and a root beer. We will be tracing lunch through the digestion process. Digestion is the process of turning the food that is ate into energy needed to survive and involves creating waste to be eliminated. (Mohan, 2010). The digestive tract is a long twisting tube that starts at the mouth and ends at the anus, called the alimentary canal. The wall of this tube is fashioned of four layers of tissue. The layers are listed from the inside coat to the outside coat: mucosa or mucus membrane, submucosa, muscularis, and serosa. The hollow space

The Earthworm, starfish, frog, fetal pig, and human all have much in common; however, some have more in common than others. Many have a matching digestive system but not a matching skeletal or circulatory system. Thought numerous dissections we can compare and contrast the various animal systems and gain knowledge on more than just the external side of an animal.

Main components in the digestive system include the teeth, tongue, salivary glands, liver, small intestine, stomach, and pancreas..The function is to digest food.

I feel as though this reading opened my eyes; I was not aware of the misinformation that was available through varies entities. Before reading this information, I would have easily googled nutrition information through the internet, and I would have trusted most of the information that would have come up. I would not have even questioned the authenticity of the information; I would have been like most people and believe what I have read. Now when I am looking for nutritional information, I will answer the five “W” questions before I so readily trust the information.

The stomach is an influential organ within the digestive system that converts the entered bolus into a semi-liquid paste like substance called chyme before it progresses further into the small intestine. This process is attained through the interplay of stomach muscles which churn the food and the mixture of gastric acid, mucus and digestive enzymes. There are numerous substances found in the stomach which contribute to the digestive process such as parietal cells that create hydrochloric acid and intrinsic factor, exocrine cells that produce mucus, chief cells and G cells. These substances aid in the chemical digestion process which represents the chemical alteration of larger molecules into its smaller subunits. Among the various substances,

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 major stages of the digestive system are ingestion, digestion, absorption, and elimination. Ingestion is the process of taking in food and water into the form of swallowing, and digestions is when the food that was consumed begins to breakdown into smaller pieces so it’s easy to be absorbed into the body. Digestion can happen with two phases, when the food is breakdown by teeth and the second phase which is the chemical breakdown, which is the breakdown of food by enzymes. The next stage of the digestive system is absorption, which absorbs the food of the digestions. The nutrients such as amino acids and simple sugars travel in the blood when then goes to the body cells, that can be broken down more or used to build a cell’s large molecule.

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

Your digestive system is distinctively designed to transform the food you eat into nutrients, which the body uses for cell repair, energy, and growth. It includes the organs associated with the alimentary canal and several accessory structures. Here's how it works.

The Digestive System is basically consist of organs that works together to help transfer food into energy to help nourish the body. The food then passes through, what is called the Gastrointestinal Tract (GI Tract). The GI Tract’s job mainly is to digest the food taken in, consume the nutrients and get rid of waste. This process is an impactful part of the immune system, which plays an important role with helping fluid not to enter the blood stream that’s due to a sore or inflamed tissue. Gastrointestinal Agents which are also known GI Agents are basically a combination of diseases and/or disorders that attacks part of the body such as the anus, liver, pancreas, bilary tract and the mouth. These agents are a part of many sub-classes of drugs such as H2 Antagonist; Laxatives; Antidiarrheal; GI Stimulants; Anticholinergic/Antispasmodics and also PPI’S (Proton Pump Inhibitors). The class of H2 Antagonist drugs which are also known as H-2 Blockers, are used to treat gastric ulcers, duodenal ulcers, GERD, or stomach bleeding.H2 Blockers works to the effect of decreasing the amount of acid produced by the stomach. These conditions may cause pancreatic problems which is damage caused by certain medications or even

Since this student had a bag of chips which is carbs and turkey sandwich which is considered protein and fat and water. The first stage in the digestive system is ingestion when the student enters his lunch in their mouth. In this stage there is mechanical and chemical digestion taken place. The mechanical digestion is take place by biting and tearing the food into smaller parts which would then be known as bolus. Chemical digestion is occurred when the three salivary glands sublingual, submandibular, and paratoid gland that secretes saliva which contains amylase. Amylase is used in this case to breakdown starch. In the mouth the carbohydrates and fat are broken down. In carbohydrates the starch and disaccharides are mixed with the salivary amylase, and in fats the unemulsified triglycerides are mixed with lingual lipase. Once mechanical and chemical digestion is complete in the mouth food continues its route to the digestive system going through deglutition. In deglutition the esophagus sphincter begins to contract in which the tongue forces the bolus upward towards the hard palate making the bolus to enter the oropharynx. Once it enter the oropharynx in order to prevent the bolus to enter the trachea the uvula and larynx rise upward and the superior esophageal sphincter starts to relax which would then allow food to enter the esophagus. Once that occurs the muscles of pharynx contract making the bolus to travel down the
