Verified step by step guidance

Understand the role of the innate immune system: It is the body's first line of defense against pathogens and includes physical barriers, immune cells, and various proteins.

Identify the function of defensins: Defensins are small antimicrobial peptides that play a crucial role in the innate immune system by disrupting the membrane of pathogens, leading to their destruction.

Differentiate between the options: Antibodies are part of the adaptive immune system, cytokines are signaling proteins, and complement proteins are part of the complement system, which aids in pathogen clearance.

Recognize that antimicrobial peptides, such as defensins, are directly involved in the innate immune response by providing a rapid defense against a wide range of pathogens.

Conclude that among the given options, antimicrobial peptides are classified as defensins in the innate immune system.
