Location & Structure The liver is the largest organ of the body weighing in at about 3 pounds and about 6 inches thick. With this size the liver is very resilient. The liver is a red-brownish organ that is shaped like triangle. The liver is located at the top of the abdomen on the right side of the body just below the diaphragm. The structure of the liver is built up of four lobes. The two main lobes are the right and left lobe. The right lobe consist of the two remaining lobes the quadrate and the caudate lobe. Each lobe is composed of thousands of units called lobules. Without the liver we wouldn’t be able to survive. The liver serves as the body’s main chemical factory. The liver stores glycogen, amino acids, and proteins along with …show more content…
This can be life threating. The liver usually has to go through a few stages before reaching such a life threating state. Many other diseases will develop into cirrhosis if not treated in time. For example fatty liver is disease that can develop into hepatitis or cirrhosis. This disease is most commonly developed by through acute alcohol abuse or substance abuse. This disease can be reversible with absence before developing into cirrhosis, but 20% of heavy users will fail to stay absent and develop cirrhosis. A second disease you might develop before getting to cirrhosis is hepatitis A, B, or C an infection of the liver can develop into cirrhosis. These viruses cause few symptoms that most of the time they go unnoticed developing into a life threating stage. All these can occur at the same time, but if cirrhosis is reached and the cells of the liver are damaged and unable to repair themselves and being to die off causing a scar to form creating blood clots. If this happens poison and waste will accumulate and if this continues for a long period of time it will lead to a hepatic encephalopathy, a condition in the brain causing confusion, change in behavior and worst case scenario a coma. A way to detect cirrhosis would include ruining some blood work, biopsy, an ultrasound, or a CT scan. If cirrhosis is detected in the liver there will be nothing that will be able to be done and as of now there aren’t any known cures. However; there are treatments available that can delay its progress. For cirrhosis caused by alcohol abuse, the person must stop drinking to stop cirrhosis from advancing. A doctor most commonly will prescribe steroids or antiviral drugs to reduce liver cells from being injured and progress to cirrhosis. Cirrhosis can be reversed depending on how the person follows their treatment plan. If they follow the plan they
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.
You look in the mirror and see that your skin and eyes seem a yellowish color, your legs and ankles are swollen, you have abdominal pain and swelling, your skin is also itchy, you have dark urine, and notice that your stool is a pale color. What do these symptoms mean? These are symptoms of damage to the liver. There are many ways to damage your liver like the use of alcohol, but a way you may not be aware of is the use of medication. Some medications when used repeatedly can cause liver damage, such as acetaminophen, also known as Tylenol.
Hepatitis is the inflammation or swelling of the liver. The inflammation can happen from different injuries or viral forms of a disease. People who experience hepatitis have the symptoms of malaise, nausea, vomiting, loss of appetite, fever and jaundice. There are six known forms of Hepatitis which are Hepatitis A, Hepatitis B, Hepatitis C, Hepatitis D, Hepatitis E and Hepatitis G. The presence of hepatitis in the body can be very risky and cause severe death if not taken care of. Hepatitis is a severe issue that affect many people around the world like third world countries and cross contamination can occur mainly in health care places due to the exposure of patients with the disease and accidents handling blood or instruments, Hepatitis A,B,C,D,E and G are distinct diseases that differ in transmission and vaccines to prevent them or cure them.
The sonographic appearance varies depending on of the Hepatitis is acute or chronic. In acute hepatitis you will see a normal texture or portal veins will be more prominent. The liver appears hypoechoic. Attenuation might be present in acute Hepatitis. Gallbladder walls are thickened and hepatosplenomegaly. In chronic Hepatitis the parenchyma will appear coarsed with decreased brightness of the portal triad. Attentuaion is not as great in chronic Hepatitis. Fibrosis may occur with soft shadowing. The size of the liver is decreased and appears hyperechoic.
The signs and symptoms of blood borne pathogens vary based on the type of disease it is and the ability of a person’s immune system to fight it off. In most cases hepatitis B does not need to be treated and the body can fight it off on its own. However a long-term infection can develop in some people that can cause liver damage. There is a vaccination available to prevent acquiring the disease. The signs and symptoms for hepatitis C are usually mild. It can take two weeks to six months after contact before signs begin to show, or there may not be any symptoms at all. Hepatitis C typically becomes is a long-term infection and after many years will cause liver ...
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).
Alcohol not broken down by the liver goes to the rest of the body, including the brain. Alcohol can affect parts of the brain that control movement, speech, judgment, and memory. These effects lead to the
two pleural lobes on the sides. The three main parts of it's body are called the
What is hepatic cirrhosis? According to the medical dictionary hepatic cirrhosis is when scar tissue replaces the liver’s healthy tissue. This disease changes the structure of the liver and blood vessels that nurture it. It reduces the liver’s capability to produce proteins and process hormones, nutrients, medications, and poisons. Cirrhosis is an illness that gets worse over time and possibly can become life threatening. This serious illness is ranked as the ninth leading cause of death in the U.S. It is the third most common cause of death for adults between 45 and 65 years of age. It occurs in more than fifty percent of undernourished chronic alcoholics. Unfortunately it kills about 35,000 people per year. In other country’s such as Africa and Asia death from cirrhosis is usually caused by hepatitis B.
There is a disease spreading out in the world called Hepatitis C. It affects the liver and may cause the liver to fail. This disease is caused by a virus called Hepatitis C virus which is also known as HCV. About 32,000 people are affected with this disease per year only in the United States area. Some It’s a disease with many symptoms and many causes. of these symptoms are easy bruising, upset stomach and fever. These are just some of the many symptoms that come from the virus. Hepatitis Cs nature of the causative agent is determined by many things. The biological data of this disease is filled so much information. It is estimated that over 180 million people have gotten Hepatitis C and it is growing.
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).
The pancreas is located in the middle of the abdomen. It’s surrounded by the stomach, small intestine, liver and spleen. It’s about six inches long and shaped like a thin pear, wide at one end. It has three sections: wider right end is the head, the middle is the body and the left end is the tail.
The liver is the largest internal organ in our body, weighing about 3 pounds. It is reddish-brown and rubbery to the touch (WebMD, n.d.). Our liver is one of the most important organs in our body. It exists to process nutrients from the food we eat, make proteins, make bile, and remove toxins. These processes can get interfered with due to liver failure, when the liver is damaged to an extent that it won’t function normally for months or years.
The role of the liver is to filter toxins and remove them from the body in the form of nitrogenous waste. Nitrogenous waste is ammonia, urea and uric acid. In the human body only ammonia and urea are produced and the liver quickly changes the harmful ammonia into the tolerable urea for excretion from the body.
Alcohol in the form of alcoholic beverages has been consumed by humans since pre-historic times, for a variety of hygiene dietary, medicinal, religions and recreational reasons. According to the NIH Senior Health, drinking too much alcohol affects many parts of the body. It can be especially harmful to the liver, the organ that metabolizes (breaks down) alcohol and other harmful substances. People who drink heavily for a long time can develop diseases such as liver inflammation (alcoholic hepatitis) or severe liver scarring (cirrhosis). Alcohol-related liver disease can cause death. According to the statistics in the year 2010 by the CDC (Centers for Disease Control and prevention) the number of discharges with chronic liver disease and cirrhosis as the first-listed diagnosis was 101,000 persons, while the number of deaths has been 31,903 persons.
