The main function of the liver is to filter the blood coming from the digestive tract before passing it to the other body parts. Glycogenesis is the formation of glycogen from glucose. It takes place in the liver. The glycogen thus formed is stored in liver. Liver also has carrier molecules and enzymes that produces urea from the ammonia, toxic base. The destruction of dead and worn-out red blood cells takes place in the liver and spleen. When the red blood cells are destroyed in the liver, bilirubin is formed. Large intestine absorbs food and excess water from undigested food prior to releasing as a solid waste.
Thus, the correct answer is 'Absorption of food and excess water from the undigested food.'

The partially digested food coming from the stomach of a person enters a long and narrow organ A in his body. The organ A receives the secretion of two glands : liver and pancreas. Liver secretes a greenish-yellow liquid B which is normally stored in the organ C. Pancreas secretes pancreatic juice which contains three digestive enzymes D, E and F. The intestinal juice completes the process of digestion of food. The inner wall of organ A has millions of tiny finger-like projections G which help in the rapid absorption of digested food into blood stream. The undigested part of food then passes into wider tube H which absorbs most of the water from undigested food. The last part of tube H called I stores this undigested food (or waste) for some time. The undigested food is then passed out though opening J as faeces in the process known as K. (a) Name the organ A. (b) Name (i) liquid B, and (ii) organ C. (c) What are the digestive enzymes D, E and F? (d) Name the projections G present on the inner wall of organ A. (e) Name (i) tube H (ii) part I (iii) opening J, and (iv) process K.

During a meal, your liver will store sugar, or glucose, as glycogen for a later time when your body needs it. The high levels of insulin and suppressed levels of glucagon during a meal promote the storage of glucose as glycogen.
The liver is a critical organ in the human body that is responsible for an array of functions that help support metabolism, immunity, digestion, detoxification, vitamin storage among other functions. It comprises around 2% of an adult's body weight.
One of the liver's functions is bile production and secretion. The liver plays a role in carbohydrate metabolism, serves as a storage of carbohydrates, where they are broken down into glucose and siphoned into the bloodstream to maintain normal glucose levels.
The liver plays an important rôle in protecting the organism from potentially toxic chemical insults through its capacity to convert lipophiles into more water-soluble metabolites which can be efficiently eliminated from the body via the urine.
Glucagon helps blood glucose levels rise back up in multiple ways, including: Glucagon triggers your liver to convert stored glucose (glycogen) into a usable form and then release it into your bloodstream. This process is called glycogenolysis.
When your body doesn't immediately need glucose from the food you eat for energy, it stores glucose primarily in your muscles and liver as glycogen for later use. Your body creates glycogen from glucose through a process called glycogenesis.
The Liver and Its Functions. The liver is the largest solid organ in the body. It removes toxins from the body's blood supply, maintains healthy blood sugar levels, regulates blood clotting, and performs hundreds of other vital functions. It is located beneath the rib cage in the right upper abdomen.
Synthesis of carbs, proteins, and lipids. Regulates blood concentration of nutrients like glucose/amino acids. Makes bile acids which break down fat. Makes cholesterol.
