The Human Skin and Its Layers
Skin is the largest organ of human body. It protects us from microbes and the elements permits the sensation of hot, cold and touch as it is one of our five sense organs. Basically, our skin has three layers: –
- The Epidermis: – It is the outermost layer of skin which is relatively thin but tough. It provides a waterproof barrier and creates our skin tone. This layer is known as stratum corneum. It keeps making new cells.
- The Dermis: – Dermis is a thick layer of fibrous and elastic tissues. This layer has a lot of tasks like: – producing oils and sweat, growing hair, bringing blood to the skin etc.
- The Hypodermis: – It is the innermost layer of our skin, also known as the fat layer. It controls your body temperature, stores your fat.
