Verified step by step guidance

Begin by understanding the primary functions of the Integumentary system, which includes the skin, hair, nails, and glands. This system acts as the first line of defense against external harm by providing a physical barrier.

Explore the role of the skin in the Integumentary system. It prevents pathogens from entering the body and helps regulate temperature, while also providing sensory information.

Next, examine the Immune system, which is responsible for identifying and eliminating pathogens that manage to bypass the physical barriers of the Integumentary system.

Understand how the Immune system uses various cells and proteins, such as white blood cells and antibodies, to detect and destroy foreign invaders like bacteria and viruses.

Consider how these two systems work together: the Integumentary system prevents most pathogens from entering the body, while the Immune system targets and eliminates any that do manage to penetrate these defenses.
