The Digestive System Essay

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.

The above explanation of digestion occurs in a ‘normal’ functioning body. There are several dilemmas involving digestion that the human body may encounter with progressed age, disease, or improper mechanics, such as lack of teeth. A major threat involving a decrease in digestion ability is malnutrition. Malnutrition does not simply refer to not eating, but also encompasses insufficient absorbance of nutrients once food has been eaten. There is a wide array of factors that may lead to malnutrition in an individual. Mechanically, the lack of teeth is a simple but yet common reason of decreased nutrition intake. Though salivary glands are stimulated upon the introduction of food to the mouth, a person with no teeth tends to avoid the more strenuous foods to chew, such as meats, carrots, lettuce, and nuts, and become partial to a lot of soft foods like potatoes and eggs, which may not necessarily be the most nutritious or balanced. Individuals with gum disease may have all their teeth, but it can become sore for them to chew their meals and, as a result, the eating dwindles. Jaw injuries or surgeries can cause discomfort and may temporarily hinder proper

The organs needed for the dissection from the digestive system contains the liver, stomach, the small and large intestines, also the tongue. The function of the liver is to clean and detoxify the blood but also to store vitamins and iron. The function of the stomach is to receive food from the esophagus and mix food with the gastric juices. Small intestines extend from the stomach to the large intestines. It is responsible for absorbing most of the nutrients into the bloodstream.

The large intestine functions to absorb the remaining water from the indigestible food matter and then to pass the matter out of the body.

The digestive and excretory systems help the body with the wonderful task of food. The digestive system is composed of the stomach, mouth, liver, pancreas, and the large and small intestine. It digests food and provides the

The colon also known as the large intestine is an important contributor to the gastrointestinal tract. After food is absorbed in the small intestine it is pushed into the large intestine where the remaining water and vitamin k is absorbed. This is where the absorption water is most important in the G.I tract in keeping excretions regular. Also, the colon is a rich source of microorganisms. Bacteria in the colon assist in the digestion of nutrients we are not able to do because we lack those enzymes that specifically breakdown carbohydrates. To disrupt the balance of the microorganisms or bacteria would in fact cause more harm to your health.

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

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

Your digestive system in particular plays a major role in your overall well being and a poor functioning digestive tract can show up through a wide range of symptoms including skin issues, headaches, energy levels or mood, you name a symptom and it can usually be traced back to something not right within your gut. Two major system linked to your guts health are your immune system and your hormone function – both can take a major hit if your gut

Your digestive system is amazing—it is comprised of a complex network of organs that work together to provide you with the nutrients from the food you eat, while eliminating harmful substances from your body. Unfortunately, the importance of digestive health is greatly underappreciated.

The digestive tract is a very resilient system, but there are some changes that occur which may cause you some distress. There is a gradual slowing of the system as well as a decrease in the secretion of saliva and enzymes which are necessary for digestion. As a result, there may be problems with indigestion, elimination and adequate absorption of nutrients.

The abdominal cavity which contains the stomach, most of the large intestine, the small intestine, the gallbladder, spleen, kidney and liver. The small intestine is very important and its job is to digest food and also take nutrients from food to help give back to the body. The gallbladder is a small storage organ also needed in digestion and holds bile products produced by the liver until needed for digesting fatty foods. The kidney is also vital because it helps aid in essential processes such as regulating blood pressure. The liver is very vital and performs multiple critical functions to keep the body pure of toxins and harmful substances. Without a healthy liver, a person cannot survive. Then the pelvic cavity which will contain also portions of the large intestine, reproductive organs, and the urinary bladder. The large intestine is also known for helping during digestion by taking undigested food and absorbing as much water as it can and expels the waste. The reproductive organs play a vital role in the survival of our species. Lastly, the urinary bladder functions as a storage vessel. It is one of the most elastic organs and is able to increase its volume

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

If the small intestine were damaged or dysfunctional, food would not be digested or absorbed into the blood stream and this could result in starvation and malnutrition. (Audesirk, T., & Audesirk, G. (1999). Retrieved November 21, 2015 from Chapter 29: Nutrition and Digestion. In Biology: Life on Earth (5th ed., p. 585, 586). Upper Saddle River, N.J.: Prentice Hall.)

The Liver the largest and heaviest organ makes bile then stores it in the gallbladder. Which stores the bile then squirts it into the small intestine to break down fatty foods if needed. Banana squeezes through the Duendom the beginning part of the small intestine connecting the small intestine to the stomach. The small intestine is a 600cm long tube, and does the most absorption in the whole digestive system through little finger like sponges called villi. Villi have capillaries located through them that absorb nutrients then leak the nutrients into the bloodstream. The nutrients are leaked into the bloodstream because cells need nutrients to be able to do their jobs for the body. Nutrients and
