The overall purpose of the digestive system The digestive system has of a chain of linked organs that work with each other to digest, and break down food into molecules that are put in the circulatory system. Then takes them to the body’s tissues. The most important structures in the digestive system are the tongue, mouth, intestines, esophagus, stomach, and anus. The liver, gallbladder, and pancreas are with the digestive system also. How does the digestive system function Food comes in the mouth, and chewing and saliva start to break it up and make it smaller to swallow. Then, the food goes down through the esophagus to the stomach. Moving of the stomach’s muscular wall keeps going to break down the food. The grinded up food eventually passes …show more content…
It holds a juice that contains digestive enzymes like trypsin,it helps digest protein foods, the juice is called, pancreatic juice. It also holds amylase and maltase, they mash down carbohydrates. And finally it also holds lipase, it works with bile from the liver to digest fat. Bile is made in the liver but held in the gallbladder, a little pitted organ found just below the liver. Bile does not have enzymes instead, it holds mostly acids, salts, cholesterol, and other materials that work with lipase to break down fats. The gallbladder can be surgically taken out without playing a major effect on the body. The liver, is crucial to live. It has a lot of important services, like getting rid of toxins from the body. The liver is needed part for metabolism, proteins and fats are incorporated here, sugars are transformed to glycogen. Then it is then kept in the liver until it is required for …show more content…
Celiac Disease is cells that line the small intestine are run down and hurt and they are incapable to take in foods regularly, specifically fats. People that have this disease are super sensitive to gluten which is a material that is found in basic grains like oats, wheat, rye, and barley.This happens because the small intestine usually digests and takes in the food and drinks that are consumed.Gluten just damages the cells lining, the small intestine is not clear, but a protein chunk of gluten named gliadin might be causing the damage. Celiac disease is usually a disease you may get if your parent has it. But sometimes you don 't know you have it until your adult years specifically after severe emotional stress, pregnancy, surgery, or a viral infection. The effected of the disease is very different in different places around the world. In Ireland 1 in every 300 people get the disease in North America around 1 in 5,000 people gets the disease. If a parent, brother or sister has celiac disease, the risk of getting the disease might be close to 10
The gallbladder according to Dorland’s Medical Dictionary is ‘the pear shaped reservoir for the bile on the posteroinferior surface of the liver, between the right and the left quadrate lobe, from its neck the cystic duct projects to join the common bile duct’. The function of the gallbladder in the human body is to solve and concentrate bile, which is produced by the liver and is necessary for proper digestion of fats.
Celiac Disease is an inflammatory disease that destroys the lining of the small intestines and prevents the absorption of nutrients and vitamins into the system. The patients' health suffers; their digestive system is unable to process gluten foods that contain wheat, barley, and oats. The cause of this disease is unknown; however, environmental factors and a genetic predisposition are suspected.
Celiac Disease was very unknown in the early 2000’s, making it hard for doctors to diagnose. Most people that develop the disease do so during adulthood, but I was born with it. From birth, my immune system would attack the protein found in wheat, rye, malt, oat, and barley; when attacking the protein, the walls of my stomach and intestines were also being damaged. I would have stomach aches and vomit almost every day. Because the doctors had not diagnosed the disease, I continued to eat gluten, and it continued to cause my body to destroy itself.
The gallbladder is a small organ that is located under the liver. The purpose of the gallbladder is to store bile and bile is a fluid made by the liver that helps digest fat. The gallbladder releases bile through a tube called the common bile duct. The common bile duct connects the gallbladder and liver to the small intestine. There are several conditions that can affect the gallbladder. This is called “gallbladder disease”, the term refers to any condition that affects the gallbladder. Gallstones and Cholecystitis, are two conditions that affect the gallbladder.
Pancreas: The pancreas is an oval organ located between the stomach and the small intestine. It makes fluids to protect the small intestine from the acid. It produces important enzymes and hormones that will ...
The digestive system otherwise known as the gastrointestinal tract (GI tract) is a long tube which runs from the mouth to the anus. It operates to break down the food we eat from large macromolecules such as starch, proteins and fats, which can’t be easily absorbed, into readily absorbable molecules such as glucose, fatty acids and amino acids. Once broken down, these molecules can cross the cells lining the small intestine, enter into the circulatory system and be transported around the body finally being used for energy, growth and repair.

Pancreas- The pancreas creates a juice that breaks down carbohydrates, fats, and proteins. "The pancreas delivers digestive juice to the small intestine through small tubes called ducts" (NIH (5).) The pancreas is not considered part of the GI tract, but it is a necessary organ needed for the digestion and absorption of nutrients.
...ve eaten, to break down the food into a liquid mixture and to slowly empty that liquid mixture into the small intestine. Once the bolus has entered your stomach it begins to be broken down with the help of the strong muscles and gastric juices which are located in the walls of your stomach. The gastric juices are made up of hydrochloric acid, water, and mucus- and the main enzyme inside of your stomach is what is known as pepsin, which needs to be surrounded in an acidic setting in order to do its job, that is to break down protein. Once the bolus has been inside of your stomach for long enough it begins to form into a liquid called chyme, and what keeps the chyme from flowing back into our esophagus are ring shaped muscles known as sphincters located at the beginnings and ends of the stomach and they have the task of controlling the flow of solids and liquids.
What happens to food once it is ingested? Where does it go? How is it broken down into smaller pieces? The digestive process is very complex, but simple to understand. It involves several steps that include from being chewed inside the mouth, to landing in the stomach for more breakdown, traveling through the intestines, and finally exiting the body.
As the digestive system breaks down your food, after it's broken down it turns into energy. Your circulatory system takes some the produced energy and transports it around the body, delivering it and other blood, nutrients, oxygen, and more compounds to every cell in your body. The digestive depends on the circulatory as much as it does vice versa because they need the blood, nutrients, and energy (broken down food) that was produced from both systems. Many digestive organs need to use about 30% of cardiac output. Both the digestive and circulatory systems get rid of unwanted or unneeded materials (waste) and feces (poop). The vial substances are absorbed by the small intestine, where it is put into the bloodstream, so it can be circulated around the body. The most important thing is that with no nutrients and circulation, there's no life.
The gallbladder is inferior and posterior to the liver. The gallbladder and its connecting ducts are referred as the biliary system. The biliary system is involved in the production and transportation of bile2. Bile is produced in the liver and when it is secreted, it flows through the cystic duct to the gallbladder to be stored. The gallbladder is a storage unit for bile. The job of bile is to emulsify fat. Also in the gallbladder, hard deposits of bile can form. Those hard deposits are called gallstones and they can be quite painful.
During digestion, the body breaks down food into smaller molecules that could then be used by the body’s cells and tissues in order to perform functions. This starts off in the mouth with the physical movements of chewing and the chemical breakdown by saliva. Enzymes in the stomach break food down further after traveling from the mouth through the esophagus. The food from here then moves into the small intestine, where pancreatic juices and enzymes dissolve proteins, carbohydrates, and fibers, and bile from the liver breaks down fats into these small molecules. Any portion of the fibers or food that were unable to be broken down are passed from the small intestine to the large intestine, which is where the digestive tract transitions into the excretory tract, then the colon and out of the rectum. Any liquids that have been stripped of their nutrients by the body proceed from the stomach to the kidneys. In the kidneys, sodium ions (Na+), uric acid, and urea are exchanged with water, which moves urinary bladder and is excreted through the
The excretory system, which includes the rectum and anus helps the digestive system by getting rid of waste and the digestive system helps the excretory system by breaking down food to be eliminated from the body. Wow! The human body wouldn’t be able to work without one or the other. Anyways, I hope you enjoyed reading my journey throughout the human digestive system. I hope to write again from where my next journey from here will begin- perhaps it will be in the ocean or along Sydney Water pipes. Until next
The digestive system is a very important system in the human body. It is a group of organs that work together to turn food into energy and nutrients in the entire body. The food that was chewed in a humans’ mouth now passes through a long tube that is inside of the body that is known as the alimentary canal. The alimentary canal is made of the oral cavity, pharynx, esophagus, stomach, small intestines, and large intestines. Those few things are not the only important accessories of the digestive system there is also the teeth, tongue, salivary glands, liver, gallbladder, and pancreas.
