Some liver questions..?

How does the liver control the amount of glucose in the blood?
What happens to excess amino acids? How is the kidney employed in this process?
How is the liver involved in regulation of the blood? Name 3 functions it undertakes.
What part does the liver play in the digestive process?
Where is alcohol detoxified and what happens to the by-products of this process?
How is the endocrine system involved in maintaining homeostasis?

That is a very complex question needing a detailed answer. How detailed an answer you need depends on what you need it for.
Glucose is converted to glycogen for storage by the action of insulin in the liver if blood glucose is too high. The liver maintains blood glucose level at about 90mg/100ml blood. If blood glucose level falls to 60mg/100ml blood, glycogen from storage is converted to glucose by a process called glycogenolysis.
Excess amino acids are deaminated because the body can’t store them. Deamination involves the removal of the -NH2 group from the amino acid along with a hydrogen atom to form ammonia. The ammonia can then be used in synthesis of nitrogenous bases for DNA formation. Or the ammonia is converted in the liver into urea for excretion. Urea is soluble in water which then can be excreted by the kidneys. The remainder of the amino acid molecule containing the carbon can be converted into carbohydrates for respiration.
Therefore the liver is involved in the metabolism of carbohydrates & proteins in the blood. Its also involved in processing & transporting lipids in the blood.
Carbohydrates, amino acids & lipids come from the first stages of digestion in the stomach by the action of hydrochloric acid. The liver breaks these down into even smaller molecules, just stores them or transports them, depending on whats needed.
I hope that goes somewhat to answering your question.
