Verified step by step guidance

Understand the levels of organization in the human body: The hierarchy includes cellular, tissue, organ, organ system, and organism levels.

Define the term 'organ': An organ is a structure composed of multiple tissue types working together to perform specific functions.

Analyze the structure of the skin: The skin is made up of multiple layers, including the epidermis, dermis, and hypodermis, each consisting of different tissue types such as epithelial, connective, and nervous tissues.

Compare the skin's characteristics to the definitions of the levels of organization: The skin is more complex than a single tissue or cellular structure, as it integrates multiple tissues to perform functions like protection, sensation, and temperature regulation.

Conclude that the skin is classified as an organ because it meets the criteria of being composed of multiple tissue types working together to perform specific functions.
