**Topic: Immune System Overview**

**Innate Immune Response**

The innate immune response is the body's first line of defense against pathogens. It consists of non-specific mechanisms that quickly respond to invaders. This response involves various physical, chemical, and cellular defenses, which are always active and ready to combat infections.

**Physical Barrier - Skin**

One of the primary components of the innate immune system is the physical barrier provided by the skin. The skin acts as a protective shield, preventing microorganisms, viruses, and bacteria from entering the body. Its structure, along with secreted substances, maintains an environment hostile to pathogens.

**Activity: Talk and Describe**

Encourage students to engage in an activity where they *talk* about the concepts learned and *describe* how the skin functions as a barrier. This promotes deeper understanding and retention of the material.

This foundational knowledge of the immune system is crucial for understanding more complex immune responses and health mechanisms.
