The liver is the largest solid organ in the human body, which is located above and to the left of the stomach and below the lungs. It normally shapes in triangular and keeps reddish-brown in hue with a rubbery texture. As the largest gland of the body, the liver carries out many vital metabolic activities like making important blood proteins and bile, converting the nutrients in our diets into substances for body taking in, and converting toxic substances in the blood into harmless substances or releasing them out of the body. When the metabolites from the body are out of the liver’s load, there may come up with kinds of disorders on this organ, such as hepatitis infection, fatty liver disease, and cancer. Common liver diseases could be diagnosed by a routine blood test which can evaluate the liver function to some degree. Furthermore, kinds of target molecules expressed on liver tissue are applied to some clinical diagnosis or basic research detections.
