The skin is made up of three layers, each with its own important parts.
1. The top layer of the skin is called the epidermis and it is responsible for making new cells, protecting the body and giving skin its colour.
2. The middle layer is called the Dermis, and is filled with elastic connective tissues. It has a number of functions; this layer is responsible for the stretchiness of the skin.
The dermis is where you'll find the root of each tiny little hair on your skin. Each root attaches to a tiny little muscle that tightens and gives you goose bumps. It contains lots of nerve endings which help make you feel things, it brings blood to the skin and the tiny sweat glands of the dermis are responsible for making you sweat.
3. The lower layer and the thickest, is known as the Hypodermis (subcutaneous tissue). Temperature control is the main function of the Hypodermis because fatty deposits and collagen are found here, which insulate our bodies and make sure that we stay warm. This layer also stores water and nutrients.
