Verified step by step guidance

Begin by understanding the concept of immunity. Immunity is the body's ability to resist or eliminate potentially harmful foreign materials or abnormal cells.

Recognize the two main types of immunity: innate immunity and adaptive immunity. Innate immunity is the body's first line of defense and is non-specific, while adaptive immunity is specific and involves the body's ability to recognize and remember specific pathogens.

Identify the role of skin and mucous membranes in the immune system. These structures act as physical barriers to prevent the entry of pathogens into the body.

Understand that skin and mucous membranes are part of the innate immune system. They provide immediate defense against infection and do not require prior exposure to a pathogen to be effective.

Conclude that skin and mucous membranes are involved in innate immunity, as they provide a non-specific defense mechanism against pathogens.
