Verified step by step guidance

Understand the role of the subcutaneous layer: The subcutaneous layer, also known as the hypodermis, is the deepest layer of the skin in the integumentary system. It primarily consists of fat and connective tissue.

Identify the main functions of the subcutaneous layer: The subcutaneous layer is responsible for insulation, which helps maintain body temperature, and energy storage, as it stores fat that can be used as energy.

Differentiate between the functions of the subcutaneous layer and other skin layers: The synthesis of vitamin D occurs in the epidermis when exposed to sunlight, while sweat production is a function of sweat glands located in the dermis.

Consider the protection against UV radiation: This function is mainly attributed to the epidermis, which contains melanin that helps protect against UV damage.

Conclude the main functions of the subcutaneous layer: Based on the understanding of its composition and role, the subcutaneous layer's primary functions are insulation and energy storage.
