Verified step by step guidance

Understand the components of the integumentary system. The integumentary system is primarily responsible for protecting the body and includes skin, hair, nails, and associated glands.

Identify the primary organ of the integumentary system. The skin is the largest organ of the body and serves as the main barrier against environmental hazards.

Consider the functions of the skin. It provides protection, regulates temperature, and allows sensation, making it the primary organ of the integumentary system.

Compare the options given in the problem. The liver, heart, and lungs are not part of the integumentary system; they belong to other systems such as the digestive, circulatory, and respiratory systems respectively.

Conclude that the skin is the correct answer as it is the primary organ of the integumentary system, responsible for various protective and regulatory functions.
