The statutory and indefeasible duty that all persons possess the built-in rights non to hold their zest in keeping their lives interfered with in whatsoever ways is frequently seen as an added statement against the development of embryos which otherwise are humans-to-be at construct. Embryonic root cells, pluripotent as they are in the early phases, offer a great chance of handling cirrhosis due to its ability to maintain on bring forthing new cells as needed whilst keeping a singular capacity to give rise to any types of cells except the trophoblastic cells of the placenta. They can develop into specialised tissue line of descents and therefore, they, in stead of donated variety meats, can be used as a replacement for those dysfunctional or damaged 1s. This irrefutably solves the liver deficit crisis, wherein patients on the improbably long graft waiting lists die expecting grafts since the givers available are evidently outnumbered by the patients in demand.
It weighs anywhere from 2. With its large size it is also a very resilient organ. It is red-brown organ roughly shaped like a cone. The liver is located in the upper right abdominal cavity immediately beneath the diaphragm. Without the liver, we could not survive. It serves as the body"s chemical factory and it regulates the levels of most of the main chemicals in the blood.
It is classified in the digestive system, because of the bile it produces. Bile is produced in the liver and stored in the gallbladder.
Although it contains no digestive enzymes, bile does dilute and neutralize stomach acid, and it increases the efficiency of fat digestion and absorption. The liver is the organ that allows us to drink alcohol. With the help of the kidneys, the liver clears the blood of Liver essay, alcohol, and other poisonous substances by absorption.
It then alters the chemical structure of the substance absorbed, makes them water soluble, and excretes it in the bile. From there, the bile carries waste, including the absorbed substance, to the small intestine, taking a pitstop at Liver essay gallbladder, where it also helps in the breakdown and absorption of fats present.
The liver also produces albumin, compliment, coagulation factors, and globin; all important proteins for blood plasma. Albumin regulates the exchange of water between blood and tissues. Compliment is a group of proteins that plays a part in the immune system"s defenses against infection.
Coagulation factors enable blood to clot when a blood vessel wall is damaged. Globin is a major component of the oxygen-carrying pigment hemoglobin. Yet another function of the liver is to produce synthesized cholesterol and special proteins that carry fats around the body.
Along with producing many important substances, it also stores a lot of important substances as well. It receives glucose ,not immediately needed, from the hepatic portal vein and stores it as glycogen.
When the body needs more energy and heat, the liver converts the stored glycogen back to glucose and releases it into the bloodstream to be used. As with the blood, the liver also regulates the blood level of amino acids, chemicals that form the building blocks of proteins.
After we eat a meal, our blood contains too high a level of amino acids. The liver converts some of these acids into glucose, proteins, other amino acids, and urea, which is passed to the kidneys for excretion in the urine.
Structure The liver contains two main lobes, left and right, which are separated by the falciform ligament, a connective tissue septum.
The liver also consists of two minor lobes, caudate and quadrate. Oxygenated blood flows into the liver through an artery called the hepatic artery and nutrient-rich blood via the portal vein. From there, the blood drains into the hepatic vein carrying carbon dioxide and plasma proteins.
Bile made by liver cells and carrying all of those harmful substances is excreted through a network of ducts called the bile ducts. As these ducts grow larger, they fuse to form fight and left hepatic ducts which join and carry the bile to the gallbladder.
The smaller bile ducts inside the liver, and branches of the hepatic artery an portal vein form the portal tracts, a kind of conduit system.
Compliments As the liver is one of the most important organs, it must be taken good care of. Liver abscesses are a common liver disorder. It is a localized collection of pus in the liver and can be caused by a diverticular disease or appendicitis and invasion by amebae, one-celled parasites; although, sometimes the cause cannot by identified.
The abscess can usually be drained through a needle inserted through the abdominal wall and guided by ultrasound. Abdominal surgery is the other option. Another liver compliment is liver cancer.
This is a malignant tumor in the liver. More commonly in the U. One way to fix this condition would be to completely remove the tumor where cirrhosis isn"t present, but that is a very rare condition.
Cirrhosis is a chronic disease of the liver characterized by the replacement of normal tissue with fibrous tissue and the loss of functional liver cells. More commonly used are anticancer drugs, which help victim survive longer.The free Biology research paper (The Liver essay) presented on this page should not be viewed as a sample of our on-line writing service.

The liver is a large, meaty organ that sits on the right side of the belly. Weighing about 3 pounds, the liver is reddish-brown in color and feels rubbery to the touch. Normally you can't feel the. Mar 31, · Liver cancer clearly has many different causes, and there are undoubtedly many different genes involved in its development.
It is hoped that a more complete understanding of how liver cancers develop will help doctors find ways to better prevent and treat them. Figure Location of liver in body. Alcoholic Liver Disease: Introduction Alcohol is used by approximately 75% of the population of the United States, with a 7% incidence of alcoholism.
Cirrhosis is caused by chronic (long-term) liver diseases that damage liver tissue. It can take many years for liver damage to lead to cirrhosis.
Chronic Alcoholism Chronic alcoholism is one of the leading causes of cirrhosis in the United States. Drinking too much alcohol can cause the liver to swell, which over time can lead to cirrhosis.
