Verified step by step guidance

Begin by identifying the primary functions of the integumentary system. The integumentary system includes the skin, hair, nails, and associated glands.

Understand that the integumentary system's main role is to act as a protective barrier. It shields the body from physical damage, pathogens, and harmful substances.

Consider the other options provided in the problem. The production of hormones and regulation of metabolism is primarily associated with the endocrine system.

Recognize that transporting nutrients and oxygen is a function of the circulatory system, specifically the cardiovascular system.

Structural support and facilitation of movement are functions of the musculoskeletal system, which includes bones and muscles. Therefore, the integumentary system is best described as acting as a barrier to protect the body from the external environment.
