The importance of the liver is imperative to the whole body due to its many active roles. One of the purposes for the liver is to regenerate damaged or dead tissue. The liver has the greatest regeneration capability of any organ in the body. When injury from viral infection, chemical toxicity, or autoimmune inflammation damage or kill liver cells; the remaining cells can compensate by doubling their metabolic function, however, if liver injury or cell loss exceeds its ability to compensate, the liver functions will diminish (RnCeus, 2015). Another function of the liver is to filter blood coming from the digestive track. When blood enters the liver, it is rich in glucose. Hepatocytes absorb much of this glucose and pack it away until when it can quickly be released as hormone insulin between meals. Hepatocytes also can absorb and store fatty acids from digested triglycerides that help maintain the homeostasis of blood glucose. As mentioned earlier, the liver also makes …show more content…
Many of these cells form tissue, then, tissue to organ, organ to organ system. Without the combination of these cells and tissues, the functions of the body would not exist. All of these functions make the liver a vital organ, without which the tissues of the body would quickly die from lack of energy and nutrients (InnerBody, 2009). The advantage of having the combination of different tissue and unique cells is that they all play their own active roles. A perfect example would be that our body cannot use medicines we take, our liver convert’s medicine into a form accepted by our bodies. Without these functions of the liver, medicine would be useless. The liver is one of the most important organs in the body with playing active roles in the digestion, metabolism, detoxification, storage, production and immunity of the human body. It is critical for survival. Unfortunately, there are more people on the donor list than available
The Hematologic System is regarded as the body’s system that regulates the movement of nutrients, molecules (macro and micro molecules), and oxygen to tissues and metabolic waste products and carbon dioxide out of the tissues (Colbert, 2009). The overall role of the hematologic system is to deliver substances needed for cellular metabolism, temperature regulation, defend the body from injury and microbial infections, and maintain the homeostatic balance or acid-base chemistry of the blood and fluid-electrolyte balance. The Hematologic System is principally made up of the blood, blood vessels, and primary organs that manufacture blood cells such as the bone marrow, spleen, lymph nodes, liver, and thymus gland (Ignatavicius & Workman, 2009). Blood is made up of three distinct components: red blood cells, white blood cells, and plasma, and its role is to transport necessary substances for metabolism (nutrients, hormones and oxygen) to cells and to remove metabolic waste products and carbon dioxide, regulation of body temperature and fluid balance, and protect the body from infections. Blood vessels simply aid the transportation of blood throughout the body, simply in and out of the heart. Spleen on its part is the largest lymphatic organ and functions as the blood filtration system and reservoir, site for fetal hematopoiesis, and mounts immune responses that act against invading infections. Bone marrow is another important component of the hematologic system, and its role is to synthesize new blood cells (Red blood cells white blood cells, and platelets) that constitute a healthy blood count while the liver functions by detoxifying the blood (Colbert, 2009).
Personal Credibility: I have always held a curiosity about the anatomy and physiology of the body and all the parts that work together to keep us alive. Equally, it is extraordinary that medical advances have made it possible to undergo surgery to replace a failing organ with a thriving new organ, further saving a life. According to the United Network for Organ Sharing statistics: Every 10 minutes another name is added to the national organ transplant waiting list. At one point in your life, you will know someone who needs a transplant.
The development of the heart is a complicated process that implicates cell specification and differentiation, including tissue formation, shaping and alteration, to create a functional organ. The zebrafish has become a potential model system to disentangle the fundamental genetic, molecular, and cellular mechanisms of cardiac development and function. The liver is one of the essential organ in mammals. It performs many functions such as help the body digest food, store energy, and remove poisons. The liver also completes many regulatory functions that are critical to fetal development and to life in general. However, failure to perform theses function can result in many mammal liver diseases. Hepatomegaly is a symptom that associate with several liver disorders. Surveys had shown that a large number of the death in the US is caused by chronic liver disease. Liver cancer is another type of liver diseases that is one of the main cause of cancer-related death worldwide.
The Hepatitis A Virus affects many different systems within the body. The first being the digestive system and the gastrointestinal system because Hepatitis A causes an acute liver infection. The liver’s job is to process nutrients, filter the blood and toxin from your body, and fight infections. It produces important blood components, proteins, and bile which helps you digest food. The liver also stores glucose and vitamins. The Hepatitis A Virus causes inflammation that interrupts the liver’s ability to perform these vital functions. Having a healthy liver is crucial to your health because it supports many other body systems. For example, one function of the liver is to produce bile which is needed to break down fats. The body stores bile in the gallbladder and then sends it to the beginning section of the small intestine. Bile is then combined with other digestive
Organ transplantation is the process of surgically transferring a patient with end-stage organ failure to a healthy, compliant organ. This can be done when a patient’s organ has ceased working, or when the organ does not meet its opportune function. In the article Organ Transplantation: The Process, the author claims that end-stage organ failure can be the product of cardiomyopathy, cirrhosis, chronic obstructive pulmonary disease, coronary heart disease, cystic fibrosis, hepatitis, diabetes, hypertension, idiopathic pulmonary disease, and short gut syndrome.. Multiple organs can be transplanted at one time. In order for a patient to get a transplant, the patient as well as the donor, have to go through a series of tests.
In order for the body to maintain homeostatic levels of energy, blood glucose regulation is essential. Glucose is one of the body’s principal fuels. It is an energy-rich monosaccharide sugar that is broken down in our cells to produce adenosine triphosphate. In the small intestine, glucose is absorbed into the blood and travels to the liver via the hepatic portal vein. The hepatocytes absorb much of the glucose and convert it into glycogen, an insoluble polymer of glucose. Glycogen, which is stored in the liver and skeletal muscles, can easily be reconverted into glucose when blood-glucose levels fall. All of the body’s cells need to make energy but most can use other fuels such as lipids. Neurons; however, rely almost exclusively on glucose for their energy. This is why the maintenance of blood-glucose levels is essential for the proper functioning of the nervous system.
One single organ donor can save the lives of eight people and that same donor can help to improve health conditions of fifty other people as said by an article on facts about donation. Organ donation is when a living or deceased person's organs are taken out by medical physicians and surgically inserted into another person's body to help improve their health condition. The receiver and donor of the organ are not the only people affected by the transplant. Families of the donor will often become relieved knowing that their loved one will be continuing to help needy people even after they are gone and the families of the receiver will also sleep better knowing that there is still a chance that someone could help the medical status of their loved one. Organ transplant has also overcome many scientific challenges. Jekyll’s actions in Dr.
Liver disease resulting from alcohol affects more than two million Americans and is one of the primary causes of illness and death. The liver frees the body of harmful substances, such as alcohol. While the liver breaks down alcohol, it produces toxins that can be even more dangerous than the alcohol consumed (“Beyond Hangovers: Understanding Alcohol's Impact on Your Health” 13). “These by-products damage liver cells, promote inflammation, and weaken the body’s natural defenses. Eventually, these problems can disrupt the body’s metabolism and impair the function of other organs” (“Beyond Hangovers: Understanding Alcohol’s Impact on Your Health” 13).
It harmonizes the blood, arranges nutrients, synthesizes proteins, and moves harmful substances out of the body. Prescription drugs, improper diet, and environmental factors can accumulate in the body causing the liver to malfunction. If the liver is not functioning properly serious illnesses and diseases can occur.
The three functions of the skeletal system are to support, to allow movement, and to protect. The skeleton is the framework of the body and also cradles its soft organs, with it the body would be just a jelly mass it wouldn’t have no definite shape and would just collapse. It supports the softer tissues and provides points of attachment for more skeletal muscles to hold all of the parts of the body upright. For example, the bones of the legs as pillars to support the body trunk we stand up. It also supports the body against the pull of gravity. The skeletal allows movement. The skeletal muscle attached to the bones by tendons and uses the bones as a simple mechanical lever system to move the body and its parts. All together with the muscles
Liver is a vital organ and performs several roles; produce proteins that help the blood to clot and removing body wastes; regulates the supply of substances such as glucose throughout the body (Potter et al., 2012). To be able to perform these functions the liver cells must function normally. Alcohol abuse is usually connected to alcoholic liver disease that permanently damaged the liver due to excessive drinking and continued excessive drinking can shorten lifespan. If liver cirrhosis has not yet occurred, the liver can heal once the patient stop drinking alcohol (ABS, 2010).
Organ donation is the surgical removal of organs or a tissue of one person to be transplanted to another person for the purpose of replacing a failed organ damaged by disease or injury. Organs and tissues that can be transplanted are liver, kidneys, pancreas, heart, lungs, intestines, cornea, middle ear, skin, bone, bone marrow, heart valves, and connective tissues. Everyone regardless of age can consider themselves as potential donors. After one dies, he is evaluated if he is suited for organ donation based on their medical history and their age as determined by the Organ Procurement Agency (Cleveland Clinic).
The main causes of liver failure include hepatitis B, hepatitis C, long-term alcohol consumption, cirrhosis and malnutrition (WebMD, n.d.). It is crucial that the affected person applies for a liver transplant. A liver transplant is an operation in which the patient’s damaged liver is replaced with a healthy liver from a donor. There are three main types of liver transplant: orthotopic transplant, the most common type of transplant, where the patient’s liver is replaced by a liver from a deceased donor; living donor transplant, where a living person willingly donates his liver for the patient; and split type of liver transplant: where the liver of a deceased donor is split into the two lobes and given to two recipients, applicable if the patients are an adult and a child ( The United States alone performs around 6,000 transplants a year (American Liver Foundation, 2013), and has performed 592,589 to date since 1988, according to OTPN (Organ Procurement and Transplantation Network) statistics. Patients have an 86% chance and a 78% chance of living one and three years after a transplant.
middle of paper ... ... en through the example of Nickolas Green, when you donate organs you not only save one life, but often numerous. Your body has so many vital organs and tissues that can be donated and given to many different people. For many of these people, what you donate to them, can be a matter of life or death.
The human body is very complex. It is like a job. You have to do a million things in one day to make it through the day. The body uses nine systems to do all of those jobs. They all have separate functions, but some work together. Each system is also made up of organs. There are many ways to care and protect the systems from the many different problems they can have. There are also many interesting facts about each system.
