Integumentary System Concepts

The video explores the integumentary system, focusing on skin's role in protection, temperature regulation, and sensory functions. It details the layers of the epidermis, dermis, and hypodermis, explaining their structures and functions. The video also covers accessory structures like sweat and sebaceous glands, hair, and nails. It highlights the importance of the integumentary system in preventing conditions like skin cancer and managing burns.
