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 do kupffer cells 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.
What else can I help you with?
Why are elevated liver enzymes and abnormal liver functions a concern?
It is a concern because it indicates the liver is impaired in some way. Which will lead to an inability to excrete toxins from the body, as well as the livers hundreds of other functions.
Is human spleen the same as liver?
NoThe spleen is an organ found in virtually all vertebrate animals with important roles in regard to red blood cells and the immune system (Wikipedia)The liver is a vital organ present in vertebrates and some other animals. It has a wide range of functions, including detoxification, protein synthesis, and production of biochemicals necessary for digestion. The liver is necessary for survival; there is currently no way to compensate for the absence of liver function.(Wikipedia)
Functions of a liver?
The liver has many functions. Some of the functions are: to produce substances that break down fats, convert glucose to glycogen, produce urea (the main substance of urine), make certain amino acids (the building blocks of proteins), filter harmful substances from the blood (such as alcohol), storage of vitamins and minerals (vitamins A, D, K and B12) and maintain a proper level or glucose in the blood. The liver is also responsible for producing cholesterol. It produces about 80% of the cholesterol in your body.
What causes a liver to be enlarged?
Liver enlargement can be caused by various factors such as fatty liver disease, hepatitis, alcohol abuse, liver cancer, or congestive heart failure. It can also result from certain medications, infections, or genetic disorders. It is important to consult a healthcare provider for proper diagnosis and treatment.
Major organs in the human body?
Some major organs in the human body include the brain, heart, lungs, liver, and kidneys. These organs play critical roles in maintaining bodily functions and supporting overall health. Any dysfunction in these organs can lead to serious health issues.
What is the importance of human resourese in an organization?
The human resources department in any company has a number of important functions. Some of these include hiring, firing, and taking care of organizing repairs to be made.
What is the evolution of the liver?
The liver has so many functions that it would have to be a very comprehensive study, documenting all the different mechanisms that developed over time, and how that gave the humans a selective advantage against pathogens and metabolisation of different foods. Talking about the regenerative capacity of the liver, I believe malaria and some other pathogens played an important role in selecting out human with a regenerative capacity in their liver.
Are the human organ are important than others could you survive without some of the organe?
Some organs are more important and necessary than others. You can't live without a heart or a liver but you can survive just fine with only one kidney.
Compare sheep organs with human organs?
Sheep and human organs have similar structures and serve similar functions. However, there are differences in size and relative proportion of organs, as well as some variations in specific anatomy and physiological processes. Both species have vital organs like the heart, lungs, liver, and kidneys that perform essential functions for sustaining life.
What are the risks of hepatitis C a?
Hep.B can cause severe Liver malfunctions that lead to death if not treated. The Liver is the "sanitary" system of the human body. It cleans impurities out of the blood before the blood recirculates to the body. Hep B slows or even stops some of those functions. It can also lead to cirrhosis of the Liver which is a break down of liver tissue. The Liver is a self healing organ and if the Hep B is found and treated in time, the liver will regenerate many of it's normal mass.
What are some human body parts?
Heart, liver, brain, small intestine, etc.
What are some of the human vital parts?
The most vital is the central nervous system and the axial skeleton. After that the heart in lungs would also be important. This can be deduced from the fact that they are the most protected parts of the body, surrounded by bone and bony structures.
