Verified step by step guidance

Step 1: Begin by understanding the question, which asks for the largest internal organ in the human body. The options provided are Kidney, Heart, Liver, and Lung.

Step 2: Recall the anatomical structure and function of each organ. The kidney is a bean-shaped organ responsible for filtering blood and producing urine, but it is relatively small compared to other organs. The heart is a muscular organ that pumps blood, but it is also smaller in size.

Step 3: Consider the liver, which is a large, reddish-brown organ located in the upper right abdomen. It plays a vital role in metabolism, detoxification, and storage of nutrients. Anatomically, the liver is the largest internal organ in terms of size and weight.

Step 4: Compare the liver to the lung. While the lungs are large in volume due to their spongy structure for gas exchange, the liver is denser and heavier, making it the largest internal organ by weight.

Step 5: Conclude that the correct answer is the liver, based on its anatomical size and weight compared to the other options provided.
