What role does the gallbladder play and how is it related to the liver?
The liver is connected by hepatic bile duct and the gallbladder by the cystic bile duct joining to form the common bile duct which joins with the pancreatic duct to form the ampulla of Vater, which opens into the duodenum.
A liver scan is usually ordered after blood studies and other imaging procedures have shown a liver abnormality. It is most often used to further evaluate masses or tumors. These may be benign growths in the liver, or cancer
What describes the purpose of the liver in the human body?
It changes the stuff you eat into the chemicals you need to live.
It also dumps a fair amount of waste aka bile salts and converts a number of poisons into water soluble salts that get removed by your kidneys
What are the names of the four lobes of the liver?
Following are the names of the 3 lobe liver of a frog such as:
1. right anterior
2. left anterior
3. left posterior
Where is the bile stored and secreted from?
The bile is secreted in the liver and then stored in the gall bladder. When the pancreatic juice is secreted by the pancreas, it gets mixed with the bile juice and some intestinal juice which helps in the digestion in the intestine.
Why were the lungs and liver and stomach and intestines removed from a body before mummification?
the brain was removed by a fire stick in to their nostrils. disturbing i know .
How does the liver help to regulate glucose levels in the blood?
When the blood sugar is very high in the body, the pancreas makes a hormone called 'insulin' this hormone tells the liver to take the excess glucose out of the blood. The glucose is stored as glycogen, a type of sugar, in the liver. The glucose in the blood falls to its correct level.
Also when we excercise, the muscles in our body use up a lot of glucose. If blood glucose falls, the pancrease makes another hormone 'glucagon'. This tells the liver to convert some glycogen into glucose and put it back into the blood. Glucose in the blood rises to its correct level.
What is the best pain killer to take when one has liver damage?
Most "off the shelf" pain killers damage your liver so you better consult a doctor. depending on where you are in the world you can consider smoking grass... You can ask your pharmacist as well. They know more about the drugs they handle than the doctor. There are also pain block specialists that may help and this is something you can discuss with your doctor. Always drink those 8 ounce - 8 glasses of water a day because it flushes out your liver and kidneys. Use bottled water!
Your liver is 27cm is that dangerous?
I just took an ultra sound the report stated my liver was enlarge it is 27cm. I am obese is 27cm considered dangerous to my health
How does the liver help maintain health?
When the blood glucose concentration becomes excessive; liver converts the glucose into glycogen. Liver converts the glycogen back to the glucose when energy is needed.
2: Metabolism
Liver is responsible for the metabolism of proteins and fats. It synthesizes blood clotting factors and stores various types of vitamins.
3:Bile secretion
The hypatocystes (cells) of liver secrete bile. The bile is stored in gallbladder.The bile duct of liver and cystic duct of gallbladder form common bile duct. The common bile duct join the pancreatic duct, the bile from common bile duct and pancreatic juice from pancreatic duct empty into duodenum (of small intestine) through the sphincter of oddi (valve) if it is opened. The opening of this valve is controlled by a hormone called Cholecystokinin.
Bile juice helps in emulsificaton of fats.
Bile is alkaline solution. Its molecules have dual nature (one end is attracted to water molecule while other is attracted to fat molecule). Thus its molecules remain in between water molecules and fat molecules (emulsification process).
If bile molecules were not present between fats and water, the fat molecules would be repelled by water molecules and be attracted to each other. The fat molecules would merge together because fats are insoluble in water. The merged fats would not be easily broken down with lipase (fat digesting enzyme).
4:Breakdown of old red blood cells
Liver breaks down the old red blood cells into bilurubin. Bilurubin is excreted in bile and urine.
5: Detoxification
Liver contains macrophages called Kupffer cells. These cells engulf and breakdown toxic matter such as microorganisms, dead cells and chemicals. Kupffer cells ingest microorganism by phagocytosis. The engulfed microorganism is called phagosome. Lysosmes in the cytoplasm of kupffer cell, fuse with the phagosome and release digestive enzymes. These enzymes breakdown and kill the microorganism.
But how does kupffer cell identify toxic matter?
There are receptors for the toxic matter on the surface of kupffer cells. The harmful particle and these receptors of kupffer cell can fit together like pieces of a puzzle. The harmful particle is then engulfed by kupffer cell.
How does the liver help to digest fats?
Bile is the liqued produced by the liver and stored and contrated in the gall bladder until needed for digestion. Bile acts like a detergent to break up large fat globules into smaller ones that pancreatic enzymes in pancreatic juice can break down small enough that fat can be absorbed through the small intestine wall. The enzyme that breaks down fat (lipids) is called lipase. When food, in the form of 'chyme', goes into the small intestine from the stomach, bile and digestive juices from the pancreus are added via the common bile duct (a tube that conveys the bile from the liver and the panreatic juice from the pancreus to the SI (small intestine)).
How long can a person live with cirrhosis with treatment?
The cure for cirrhosis is a liver transplant. If that is the treatment which you are offered/choose to take, your life expectancy should not be diminished. Life expectancy with cirrhosis is measured in adults with something called the "MELD" score (model for end stage liver disease) - it is an algebraic formula, based on results such as blood tests etc... you can work out your own life expectancy using the formula, should you wish to know. See related link for the MELD calculator.
The bile is stored in the gallbladder and after it leaves the gallbladder it travels to the duodenum. Bile is a very powerful antioxidant which helps in removingÊ toxins from the liver.
What is the function of liver gland?
Yes.
It is the largest internal organ and also a gland. It is considered a gland because it makes and secretes bile. Glands are organs or parts of organs that make and secrete substances. And bile is a fluid that both aids in digestion and transports fats as well as waste products into the intestine.
So that's why it is defined as a gland.
What does the liver do in a pig?
In New Zealand at least, the meat will be accurately described by the butcher. The usual liver will be either chicken or sheep/lambs. Cow's liver is enormous, and though I've never bought any, I seem to remember pig's liver being on sale.
How much glycogen can the liver store?
All together the avg. human can store approx. 500-600g of glycogen. Skeletal muscle holds twice that of the liver,, so approx. 200g for the liver and 400g for the muscle. In endurance type sports like cycling at 70%vo2max this equates to about 2 - 2.5hrs of exercise before glycogen depletion but this varies from individual to individual based on how well trained the athlete and the training protocols used. It is interesting to note that the body places a pref on liver glycogen over muscle glycogen during prolonged exercise and that fasted exercising increases overall glycogen storage capacity. whether in the muscle alone or liver or both is uncertain.
How many liver does human body h ave?
What is it general size of the liver?
In the average adult the liver weighs about three and a half pounds (1.6 kilograms). It measures about 8 inches (20 cm) horizontally and 6.5 inches (17 cm) vertically and is 4.5 inches (12 cm) thick.
What Asian Americans are most at risk in developing liver cancer?
Asian Americans with cirrhosis have four times as great a chance of developing liver cancer as Caucasians with cirrhosis, and African Americans have twice the risk of Caucasians.
It filters stuff, metabolises things, creates needed proteins and biochemicals for digestion. While having no liver won't kill you instantly, you do need these functions. Without it, you turn kind of yellow, your abdomen distends, your urine gets dark, your skin gets itchy, and then you die.
