Did you know that the skin is the largest organ of the body? Human adults carry around 3.6 kg and around 2 sq. mt of it! The main function of the skin is to protect the body from external factors such as heat, light, injury and infection.
The skin has multiple layers, each with its own unique function. Before we look at them, can you identify and label these layers correctly? Drag & drop the names in the right boxes.
Layers of the skin
Epidermis: It is the thin outer layer of the skin. It consists of 3 types of cells: Squamous cells (the outermost layer that is constantly shed); Basal cells; and Melanocytes (make melanin that gives the skin its colour.)
Dermis: The middle layer of the skin which contains the blood vessels, hair follicles, sweat glands and nerves, among others. They are all held together by a protein called collagen. This layer gives the skin its flexibility and contains pain and touch receptors.
Subcutaneous tissue (fat layer): It is the deepest layer of the skin helps conserve the body’s heat and protects the body from injury by acting as a shock absorber.
