Which is the largest internal organ in human body–

Correct option is D

Sol. The liver is the largest internal organ in the human body. It weighs about 1.2 to 1.5 kilograms in adults and performs more than 500 vital functions, including detoxification, protein synthesis, and production of bile for digestion. It is located in the upper right portion of the abdomen, beneath the diaphragm. The liver is also responsible for storing glycogen and processing nutrients absorbed from the digestive tract. Its ability to regenerate damaged tissue is unique among organs.
Explanation of each option:
· (a) Brain – Incorrect. The brain is the largest organ in the central nervous system but not the largest internal organ overall. It weighs around 1.3 to 1.5 kg but has different function and structure.
· (b) Heart – Incorrect. The heart is a muscular organ responsible for pumping blood, but it weighs only about 250–300 grams and is much smaller than the liver.
· (c) Kidney – Incorrect. Kidneys are bean-shaped organs that filter blood, but they weigh around 120–150 grams each, which is much less than the liver.
· (d) Liver – Correct. The liver is the largest internal organ, performing hundreds of essential functions like metabolism, detoxification, and nutrient processing.
