Liver, pancreas, and gallbladder, are the solid organs that make up ones gastrointestinal (GI) track – or digestive track. The digestive system helps our body take in and digest the food we eat, and get rid of the excess that our body doesn’t need. The pancreas supplies digestive enzymes for the small intestine to help break down carbohydrates, proteins and fats, while also producing the hormones insulin and glucagon to help regulate our blood sugar (Division of Gastroenterology). The liver produces a liquid called bile, which is stashed into the gallbladder. When needed, it releases the bile into the small intestine to help break down dietary fats (Division of Gastroenterology). The body breaks down nutrients from food and drink into carbohydrates, …show more content…
protein, fats, minerals, and vitamins and uses them for energy, cell repair and growth (NDDIC) to fuel the body. As the food we eat passes through the GI tract, our body makes digestive juices.
The enzymes in the juices are stimulated by hormone and nerve regulators which help them mix with the large pieces of food and breaks it down into smaller molecules. Then the body absorbs the smaller molecules through the walls of the small intestine into the bloodstream, and delivers them to the rest of the body (NDDIC).
Situations affecting the liver, pancreas, and gallbladder can affect the ability of our body to produce enzymes that help support digestion. Hepatitis, is when the liver becomes inflamed and possibly loses its ability to function. (Kids Health) There are different types of Hepatitis, such as hepatitis A, B, or C, and are very contagious and depending on how serious the liver is damaged, it may require hospitalization– however, mild cases of hepatitis A can be treated at home (Kids Health).
Cystic Fibrosis is a chronic illness that not only affects the lungs but also causes thick mucus to block the pathways in the pancreas. The mucus prevents digestive juices from entering the intestines, which makes it more difficult to digest proteins and fats and also causes important nutrients to pass out of the body unused (Kids
Health). A condition called Cholecystitis, is the gallbladder developing gallstones and becoming inflamed. Although gallbladder conditions are uncommon in kids and teens, they can happen in those who have sickle cell anemia or are being treated with certain long-term medications. (Kids Health). The digestive system is an important part of the body. It is how we get the protein, vitamins, minerals, and other things to help fuel our body. We can keep a healthy digestive system by eating healthy, reducing stress, maintaining a healthy body weight, staying active, and avoiding tobacco (Division of Gastroenterology). Getting a screening is also a great way to make sure things are running smoothly and to treat health risks early.
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.
Infections, for example, sinusitis, bronchitis, and pneumonia add to long-term lung damage. Cystic Fibrosis also causes damage to the pancreas because the thick mucus blocks tubes, and ducts, preventing enzymes from reaching the intestines. When this happens, the digestive system is unable to ingest fundamental fats and proteins, causing diarrhea, serious constipation, and intestinal blockage. As CF worsens, more serious manifestations rise like bronchiectasis, pancreatitis, hepatopathy, and diabetes. Treatment:
Gallbladder is a green pear-shaped muscular saclike organ measuring 7.5 to 10cm long. It is located inferiorly to the right lobe of liver as well as superiorly to the pancreas and duodenum. The main function of the gallbladder is to store a small amount of bile and release it into small intestine. Bile is produced in liver by hepatic cells, which contains cholesterol, bile salts, body salts and bilirubin. Gallbladder concentrates bile by absorbing water and salts. Bile then release into the cystic duct and moves down to the common bile duct in order to enter the duodenum.
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
Hepatitis A is a usually short acting virus that occurs in humans and monkeys. It is caused by the Hepatovirus and the species is Hepatitis A Virus. There are two major ways in which Hepatitis A can be transmitted. One way is from person to person. This transmission occurs when the fecal matter of an infected person gets ingested by another person. Other ways Hepatitis A can be transmitted from person to person are through direct contact with an infected person, such as sexual contact, and sharing of needles for intravenous drug use. Hepatitis A can also be transmitted through coming in contact with contaminated food or water. Also foods that are uncooked or undercooked and have been contaminated with Hepatitis A can transmit the virus. (Bennett,
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.
In the Shadow of Illness, the book describes different experiences of families who have or had children with cystic fibrosis (CF). CF is an inherited disease that is passed on from the mother or father who is a carrier, but doesn’t have the condition. Doctors have figured that in this scenario, the parents are likely to have a child with CF. Individuals with CF have to take Cotazymes to help the pancreas digest food. If the person does not take these enzymes, the food goes straight through them as diarrhea. Also, the person’s lungs are affected by a thick mucus that must be removed or thinned before it clogs. Doctors recommend the patient to perform daily breathing exercises that prevent the mucus from thickening; for example, swimming
Absorption is the way of digesting the food molecules into the small intestine. This process of absorption pass throughout the wall of the small intestine into the bloodstream. The bloodstream carried out all important nutrients to the
The pancreas is an elongated and flattened gland located within the abdomen. Not only is it a vital part of the digestive system, but it is also a key controller of blood sugar levels. (The Pancreas). The pancreas has been divided into four regions which are the head, neck, body, and tail. Being the widest part of the pancreas, the head is twenty-three millimeters. The part of the head that hooks towards the back of the abdomen is the uncinate (Chronic Pancreatitis Imaging). Between the head and body of the pancreas is the neck, which is about nineteen millimeters. The body of the pancreas is twenty millimeters, between the neck and the tail. The tail is the smallest part of the pancreas, measuring at only fifteen millimeters. (Parts of the Pancreas). The length of the pancreas in total ranges from four point seven to seven point one inches. The pancreas also weighs from seventy to one-hundred grams (How does the Pancreas Work?).
The digestive system, in organisms like the mink and human, is supposed to break down the food being eaten to transfer into energy. This energy helps other functions of the body that would in turn keep it alive. The digestive system includes organs such as the stomach, intestines, liver, etc. Digestion starts at the mouth, though.
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.
Insulin also tell the liver to shut down sugar production. It also influences the metabolism of fats and proteins. Second, glucagon is a peptide hormone secreted by alpha cells. If blood sugar a hormone is low, the pancreas releases glucagon that tells the body’s cell and liver to release stored sugars back into the bloodstream. Pancreas produce enzymes which is protein such as amylase, protease and lipases. It used to speed up the biochemical reactions and helps to digest macromolecules into much smaller molecules so the intestines can absorb them easily. Amylase is divide carbohydrates or starches to create energy-rich sugars such as glucose. Protease is helps to splits up proteins into amino acids. Lipases is helps break down fatty substances. Digestive enzymes are so strong, so a protective layer is need to wrap the enzyme while enzyme are travel to reach gastrointestinal tract from the pancreas. They travel through the pancreatic ducts and are eventually released into the duodenum at the most of papilla. The digestive enzyme become active after the protective layer is removed when they totally out of
The human digestion system is very complex. It starts with the mouth, salivary glands, pharynx, esophagus, stomach, liver, pancreas, gallbladder, small intestine, large intestine, then ends/exits with the anus. Each step is essential to the whole system. For example, the mouth chews food and mixes it with saliva produced by the salivary glands, and then the pharynx swallows chewed food mixed with saliva, this is followed by the food traveling through the esophagus to the stomach where the food gets a bath and mixes with acids and enzymes. After the stomach, the liver, pancreas, and gallbladder produce, stores, and releases bile and bicarbonates. Bile is produced in the liver and aids in digestion and absorption of fat while the gallbladder stores bile and releases it into the small intestine when needed. Following the process into the small intestine, this is where nutrients will be absorbed into the blood or lymph (most digestion occurs here). Next is the large intestine this is where water and some vitamins and minerals are absorbed. Finally, it is the end of the road, the anus. At...
The pancreas is one of the essential organs in the human body and belongs in the Digestive system. Out of all the internal organs, the pancreas is unique because the pancreas plays a role in both the endocrine gland and the exocrine gland. This means that the pancreas is a dual function gland in which is the reason why the pancreas is such a vital part of the digestive system. This research paper will talk about the anatomy, physiology, and the important functions the pancreas play to maintain homeostasis.
Cystic fibrosis (CF) is an inherited disease that the affects the exocrine glands. CF is located on chromosome 7 and is made up of 250,000 DNA nucleotides. This produces a large amount of sticky mucus which blocks the pathway of the Pancreatic ducts, Bronchi, Lungs, Digestion system and the Theintestines. CF controls the movement of chloride ions in and out of cells. This is important for the salt and water balance on epithelial surfaces, such as the lungs or the pancreas. The bacteria created by the mucus causes the damage to the affected areas. This will often result in respiratory system to be infected. This leads to irreversible damage to the body.
