Verified step by step guidance1
Step 1: Understand the concept of an organ in the human body. An organ is a group of tissues that work together to perform specific functions. Examples include the liver, lungs, heart, and skin.
Step 2: Recognize that the skin is classified as an organ because it consists of multiple layers of tissue (epidermis, dermis, and hypodermis) and performs vital functions such as protection, temperature regulation, and sensation.
Step 3: Compare the size of the listed organs. The liver, lungs, and heart are internal organs, but the skin covers the entire external surface of the body, making it the largest organ by area and weight.
Step 4: Note that the skin has a surface area of approximately 1.5 to 2 square meters in adults and weighs about 8-10 pounds, which is significantly larger than the other organs listed.
Step 5: Conclude that the skin is the largest organ in the human body based on its size, weight, and functional importance.
