  1. ASSIMILATION OF DIGESTED FOOD

  2. ASSIMILATION OF DIGESTED FOOD • Some of the digestion product are brought to the liver for processing, and undergo for metabolic processes or assimilation. • The liver act as a checkpoint. It will control the amount of nutrients release into the blood circulatory system. • In animal, most of the glucose will be converted to glycogen and stored in the liver. • There are three process that take place in the liver. 1. assimilation 2. deamination 3. detoxification

  4. GLUCOSE • Glucose are used in the cellular respiration to produce the energy. • Excess glucose will be converted into glycogen and stored in the liver. • when the blood sugar level falls and the body needs energy, the stored glycogen is converted back into glucose. • When the glycogen stored in the liver is full, the liver will converted the glucose into lipids.

  5. AMINO ACID • Amino acid also must pass through the liver before reach the circulatory system. • Liver will synthesis plasma protein from amino acid. Plasma protein involved in blood clotting and osmoregulation. • The amino acids also can be converted into glucose if there is a short supply of glucose and glycogen. • Amino acids also be used to synthesised new protoplasm and repair damage tissue. • Excess amino acids cannot be store in the body. • So, it will be broken down in the liver by a process called deamination. The urea are transported to the kidney to be excreted.

  6. LIPID • Lipid are transported in the bloodstream to the body cell. • Excess lipids are stored in the adipose tissue. • When the body lacks glucose, fats are oxidize to release the energy. • Some lipid, such as phospholipid and cholesterol are the major component of plasma membrane.

  7. Other function of liver • The liver also involved in detoxification process. • This is the process which the liver remove harmful substances from the blood to convert the compounds which are less toxic. • All the harmful product are then eliminated from the body through the bile or urine.
