Verified step by step guidance

Understand the role of interferons and complement in the immune system. Interferons are proteins that are part of the body's defense mechanism against viruses, while complement is a group of proteins that enhance the ability of antibodies and phagocytic cells to clear pathogens.

Recognize the distinction between the innate and adaptive immune systems. The innate immune system provides a general defense against pathogens and is the body's first line of defense, while the adaptive immune system is more specific and involves memory cells.

Identify that interferons and complement are part of the innate immune system because they provide immediate, non-specific defense mechanisms against pathogens.

Consider the options given: Hormonal regulators, Cellular immune responses, Adaptive immune system components, and Innate immune system components.

Conclude that interferons and complement are examples of innate immune system components, as they are involved in the body's initial response to infection and do not require prior exposure to a pathogen to be activated.
