Layers of the Skin
In Layers of the Skin, evolutionary biologist Ben Garrod explores the fascinating science of skin and how mammals, amphibians, fish, reptiles, and birds share a similar basic skin structure, despite differences in appearance and function. Learn about the three main layers of skin: the epidermis, dermis, and subcutaneous fat layer. Each layer plays an important role in helping animals adapt to their environment, providing protection, flexibility, and sensitivity. See how skin can be tough, flexible, colorful, and capable of growing feathers, hair, and even teeth. This video is excerpted from BBC’s Secrets of Skin, a documentary series exploring the natural history of the body's largest organ.
Lesson Express
Q: What are the three layers of skin mentioned in the video?
A: The three layers are the epidermis (outer layer that provides protection), dermis (middle layer containing blood vessels and nerves), and subcutaneous fat (insulating layer that stores energy and helps maintain body temperature).
Q: How does skin help animals adapt to their environments?
A: Skin provides protection, flexibility, and sensitivity, enabling animals to survive in various climates and situations.
Q: Why do you think skin adaptation is important for the survival of different species?
A: Skin adaptations are vital because they help organisms survive environmental challenges such as temperature changes, predators, and physical conditions. These adaptations allow species to better fit into their ecosystems and continue evolving.
