The digestive tract starts in the mouth and then goes to the pharynx. Then goes to the esophagus. Then from the esophagus then to the stomach. From the stomach it goes to the small intestines. Where the food is broke down using the enzymes of the pancreas and bile from the liver. Then thru the colon and the rectum and then out the
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 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 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 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 digestive system begins in the human’s mouth. With the use of the teeth, tongue, and, salivary glands the breaking down of food will begin to take place. The teeth are living organs that contain blood vessels and nerves under the dentin, which are
Picture this: you parents took you out for a family dinner and you order the Cheeseburger. Your stomach starts to growl while you are waiting for your food. You become impatient. Suddenly, you smell the warm freshly baked food that is coming you way. The waitress sets down the food carefully as you almost grab the plate out of the waitresses hands and start to eat. You ate that cheeseburger like that was you last meal. Of course you were hungry, but what is the REAL reason behind being so hungry?
This week reading deals with disorders involving the gastrointestinal tract (GI). There are several diseases of the GI tract that have clinical features that overlaps. The purpose of this assignment deal with three pacific disorders of GI tract, gastroesophageal (GERD), peptic ulcer disease (PUD) and gastritis, as a nurse practitioner, knowing the pathophysiology and similarities will assist in making a differential diagnosis in order to provide the appropriate
Primarily blood and blood products transmit the virus. The majority of infected individuals has either received blood transfusions prior to 1990 (when screening of the blood supply for HCV was implemented) or has used intravenous drugs. Sexual transmission between monogamous couples is rare but HCV infection is more common in sexually promiscuous individuals. Perinatal transmission from mother to fetus or infant is also relatively low but possible (less than 10%). Many individuals infected with HCV have no obvious risk factors. Most of these persons have probably been inadvertently exposed to contaminated blood or blood products. (Worman, M. D.)
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
The human liver is one of the most important organs in the human body. It has over 500 functions and is able to regenerate its cells. The liver, being an important part of the digestive system, functions to digest fats, filter drugs and poisons, store nutrients like vitamin A,D,E,K, and B12, secrete bile, and remove excess glucose from the body and store it until it is needed. Other functions of the liver include synthesizing proteins, production and regulation of chemicals such as globin (one of the chemicals in hemoglobin), and fibrinogen and prothrombin (for wound healing), and immune and clotting factors, just to name a few. The liver is unique because it can lose a majority of its tissue and still be able to function properly. Although the liver is able to regenerate itself, there may come a point when it suffers irreversible damages caused by disease, life style, or even a birth defect. When this happens many people either succumb to death or they fight for life and opt for a liver transplant (auuuu, 2015).
The abundance of our body’s ability to carry out the functions required to sustain itself, relies heavily on our diets. And not “diet” in terms of a fad you might read about in a health magazine, but rather in terms of the food we consume for the nutrient contents it contains. This is also referred to as a food’s nutrient density. In addition to the food choices we make, a vital system in our bodies is composed of several organs that work together to chew, swallow, breakdown, absorb, and expel what was once lunch, into usable energy for every day tasks (Yale, Kathleen). This system is known as our digestive tract, or our gastrointestinal tract (GI). Of the many important organs that make up the GI tract, our stomach acts as an intermediary
“Digestive diseases are disorders of the digestive tract, which is sometimes called the gastrointestinal (GI) tract” (Eisner, 2014). “The gastrointestinal (GI) tract is a flexible muscular tube that extends from the mouth, through the esophagus, stomach, small intestine, large intestine and rectum to the anus” (Whitney & Rolfes, 2012). During digestion, the body breaks down foods into nutrients to prepare for absorption. During absorption, the cells of the small intestine take the nutrients and send them to the blood or lymph cells (Whitney & Rolfes, 2012). After absorption, the body uses the nutrients for energy and building blocks for the cells. The digestive tract consists of: the esophagus, stomach, large intestine, small intestine,
When food is swallowed it passes from the pharynx into the esophagus, which lead to peristalsis (contractions) of the esophageal wall, which propel the food along toward the stomach. The pharynx extends from the base of the skull down to the sixth vertebrae only by some loose fibrous tissue and is about 12.5cm long. Pharynx is another name for our throat if anyone was wondering. As we approach Mr. Doe’s stomach, you should know that the stomach is a large, muscular and a somewhat J-shaped sac. Now that the stomach is in sight, you can see that it occupies the left side of the abdominal cavity. The upper part of the stomach that you see is called the cardiac. The middle dome-shaped area is the body and the distal part is called the antrum. The cardiac end is where the stomach connects with the esophagus and opposite from that is where the duodenum connects with the stomach. If you’re wondering how the stomach digests food, listen up! The smooth muscles in the stomach help push the food through. It breaks down the food with various chemicals in the process. It passes the food into the small intestine which surprisingly absorb most of the nutrients. I mentioned something about the duodenum a few moments ago if anyone remembers. The duodenum has a ‘C’ shape and is the first section of the small intestine where most absorption occurs. Also, it opens up into the jejunum. If you are paying attention,
The digestive system comprises of multiple organs like the mouth, which consists of the salivary glands, saliva, tongue and epiglottis; the Pharynx, Oesophagus, Diaphragm, Stomach, Spleen, Liver, Pancreas and the Lower gastrointestinal tract which includes the small and large intestine and the caecum. The major role of this system like it suggests is to digest food. It digests and provides nutrients to the body and passes on the waste to the excretory system to safely pass it out of the body. The Mouth breaks down the food into small components which are then accordingly absorbed and assimilated into the body. The salivary glands secrete saliva which also helps in the production of bolus which makes the task easier and it is then swallowed by the oesophagus and passed right down into the stomach. The saliva contains a catalytic enzyme called amylase which starts working on the food in the mouth itself and digestion is also helped due to the mastication of the food by the teeth and muscular contractions of the peristalsis.
The digestive system are one of the eight systems that keep the body functioning properly, the function of the digestive system is to break down macro nutrients which are large and soluble into small and soluble nutrients so that it can be absorbed into and used by the body. This process is played out in the alimentary canal which is the whole passage along which food passes through the body from mouth to anus during digestion.
