Which is the Largest Internal Organ of the Human Body
The liver is the largest internal organ in the human body and plays a crucial role in maintaining overall health. It is also the largest gland in the body, performing over 200 vital functions. When considering both internal and external organs, the liver is the second-largest organ, with the skin being the largest.
Size and Weight of the Liver
The liver is the largest organ in the body in terms of internal organs. In an average adult, it weighs between 1.35 to 1.59 kilograms, accounting for approximately 2% of total body weight. It is located in the upper right section of the abdomen, beneath the diaphragm and above the stomach, spanning across the width of the body.
Functions of the Liver
The largest internal organ of the human body is responsible for several essential functions, including:
Metabolism and Energy Supply: The liver helps regulate blood sugar levels by storing and releasing glucose as needed.
Detoxification: It filters toxins, drugs, and harmful substances from the bloodstream.
Digestive Functions: It produces bile, which aids in the digestion of fats.
Nutrient Storage: The liver stores iron, vitamins (A, D, E, K, and B12), and minerals essential for the body.
Immune System Support: It helps combat infections by breaking down bacteria and harmful substances in the blood.
The Liver's Unique Regeneration Ability
Unlike most organs, the liver has an incredible ability to regenerate. Even if 50-60% of liver cells are damaged, such as in cases of paracetamol (Tylenol) overdose, it can repair itself completely within 30 days, provided there are no further complications. This regenerative capacity is why partial liver transplants are possible, where a donor can donate a portion of their liver, and both the donor's and recipient’s livers can grow back to full size over time.
Interesting Facts About the Liver
Apart from being the largest body organ internally, the liver has some fascinating features:
