Liver Anatomy And Physiology Essay

“Cirrhosis is a common cause of death worldwide. In the United States, about 35,000 people die of complications of cirrhosis each year.” (Civan) The liver is an expansive, substantial organ that sits on the correct side of the abdominal cavity. With this in mind, the liver roughly weighs three pounds, is rosy darker in shading and feels rubbery to the touch. Ordinarily, the liver cannot be felt, since it 's ensured by the rib cage, but is the biggest minimized organ in the human body. The liver 's primary activity is to channel the blood originating from the stomach origin, before passing blood to whatever remains of the body. The liver additionally detoxifies chemicals and processes drugs. As it does as such, the liver secretes bile that winds up back in the digestive organs. The liver likewise makes proteins essential for blood thickening and different capacities. A sound liver is

There is the right larger lobe and the left smaller lobe. There are 1.5 quarts of blood transported to the liver every minute through the hepatic artery and portal vein. Because the fact that the liver produces bile it is considered a gland. The liver is part of the digestive system. This system consists of the stomach, small intestine,large intestine, pancreas, liver, and gallbladder.

The Digestive System The digestive system is a system consisting of the mouth, oesophagus, stomach, gallbladder, small intestine, large intestine, the rectum and the anus. The functions of the digestive system are: • To break down food particles into molecules for digestion • To absorb into the bloodstream the small molecules produced by digestion • To eliminate un digested and unabsorbed foodstuffs and other waste products from the body The full digestive process begins at the mouth. The food enters the mouth and is chewed.

“The esophagus is a muscular tube that connects to the mouth, to the stomach that makes food easier to swallow and move along. The stomach is a j-shaped muscular pouch holds all the food that the body swallows. The gallbladder is an organ that stores bile passing through a tube from the gallbladder to the small intestines. Bile a

The liver is responsible for hundreds of functions; it is the largest and most complex organ in the body. Weighing in at three pounds it sits behind the ribs on the upper right side of the abdomen and almost covers the entire width of the body. Nutrients and energy, the body 's fuel supply, is processed, converted and distributed by the liver. So, if anything obstructs these processes it will have a serious impact on the body as a whole. And the biggest obstacle would be the presence of gallstones.

Introduction Living donor liver transplantation (LDLT) is a lifesaving alternative to deceased donor liver transplantation (DDLT) for patients with end stage liver disease. Best matching between graft size and recipient weight is crucial to avert small for size syndrome and its serious complications. Liver represents approximately 2% of the total body weight and liver graft required to meet metabolic demands should be 40-50% of liver weight which in parallel equals 0.8-1% of the recipient’s weight. This lead to the concept that graft to recipient weight ratio (GRWR) should be at least 0.8% for successful liver transplantation [1-9]. To obtain the desired GRWR of 0.8% or more, accurate estimation of graft weight is required.

The liver is the organ affected during an Hepatitis B infection. The liver is located in the right upper quadrant of the abdomen and has several important functions. The function of the liver is to remove excess glucose, which is also known as blood sugar, from the blood stream and stores it as glycogen ( a form of starch ). When the blood sugar level is low, the liver converts glycogen back into glucose and releases it for use by the body. The liver also destroys old erythrocytes, which are red blood cells, removes poisons from the blood, and manufactures some blood proteins. The liver secretes bile, a digestive juice containing enzymes that break down fat. Bilirubin is in bile. This is a pigment produced from the destruction of hemoglobin.

The blood seeps in the sinusoids on its way to the hepatic veins, and then to the vena cava. This filtration is ideal for hepatocytes to filter the blood, process and store nutrients, cleanse, and remove debris. 6. Cirrhosis leads to scarring and increased hydrostatic pressure in the hepatic portal vein. Explain why this increased venous pressure causes net filtration to increase in the hepatic capillaries, leading to ascites (swollen and fluid-filled interstitial space of the abdomen).

Within the organs of the fetal pig, its colon is different in structure than that of human since the fetal pig colon is spiral. The fetal pig uterus has two big horns in addition to the body while the human uterus has small uterine horns. The large uterine horns on the fetal pig allow for a litter of 8 to 10 pigs. In fetal pigs, “the brachiocephalic artery splits into the right subclavian artery and the bicarotid trunk which then splits into the right and left common carotid arteries” (“Human/ Pig Comparisons”). Nonetheless, humans do not have a “bicarotid trunk and instead the left common carotid artery branches directly from the aorta” (“Human/ Pig Comparisons”).

Liver – the human liver has four lobes: right, left, caudate and quadrate. The fetal pig liver has five lobes: right lateral, right central, left central, left lateral, and caudate. Intestines – there is a significant difference in the structure of the fetal pig colon compared to the human colon. The pig colon is spiral. (See p. 45 of the FPDG.)

Liver Cancer When a specialist for any disease wants to know about particular disorder they have to know about the whole disease like diagnosis , symptoms, and the proportion of people who are susceptible to effects of this disease .Liver cancer like any disease has many characteristics .Knowing the stages help the doctor to decide what kind of treatment is best and may help to predict a patients prognosis which is the chance of recovery. This essay will identify the main stages of development of liver cancer and some possible treatment options of each stage .The

Cholesterol is a waxy fat-like substance that is produced in the liver.40 Cholesterol is necessary to make hormones such as estrogen and testosterone. It is a key ingredient in cortisol which helps control the inflammation. Cholesterol is necessary for vitamin D production from sunlight. It also helps create bile acids that digests fats. Cholesterol also plays a significant role in the synthesis of cell membranes. Cholesterol is insoluble in water so it needs the transportation facility from a protein to move them around in the body through bloodstream to fulfill their role in the membrane biogenesis. Cholesterol circulates in the bloodstream and enters cells by receptor-mediated endocytosis. Instead of circulating freely, cholesterol molecules

In order for cells to energy stored in triacylglyceride, mobilization of triacylglyride into fatty acids and glycerol, activation of acetyl-CoA and their subsequent transport to the mitochondria and finally degration of fatty acid into acetyl-CoA and generation of ATP. Triacylglycerol is broken down into glycerol and fatty acids by the enzyme triacyglyceride lipase. The fatty acids binds to serum albumin and travels through the bloodstream to the mitochondria while the glycerol travels to the liver for metabolism because the fatty acids of the triglyceride is insoluble in water and therefore cannot travel through the bloodstream. The
