The subcutaneous layer is mainly made of ___.
Gelneren [198K]

The subcutaneous layer is mainly made of  <u>fat tissue.</u>

One of the three layers of skin is the subcutaneous layer, which lies below the dermis. The deepest layer of the skin is primarily made up of fat. It also contains collagen, blood vessels and nerves. The body's fat creates a layer that protects the organs from damage and acts as insulation against the cold. Additionally, it gives the skin structural support.

The depth of the subcutaneous layer in the body's abdominal region, which frequently has higher percentages of fat, can reach three centimeters. The thickness is determined by the person's overall body fat percentage. Other places, like the eyelids, have a subcutaneous layer that is as thin as 1 millimeter and devoid of fat.

The subcutaneous layer has many functions, including insulation, thermoregulation, shock absorption, structural support, and energy storage.
