In human body which one among the following is the largest in size?
Explanation
Among the options provided, the liver is the largest organ in size and weight. It is classified as the largest solid internal organ in the human body, weighing approximately 1.36–1.59 kilograms (3–3.5 pounds) and being roughly the size of a football [t1][t2]. In comparison, the other organs listed are significantly smaller: the spleen has an average weight of about 175g, the pancreas weighs approximately 70g, and the thyroid gland is the smallest at roughly 20g [t8]. While the skin is the largest organ overall (covering the external body), the liver holds the title for the largest internal parenchymatous organ [t1][t2][t9]. It plays a critical role in the digestive system by secreting bile and processing nutrients [c1][c3]. Historical anatomical comparisons also confirm that the liver is roughly four times larger than the spleen [t10].
