Verified step by step guidance

Understand the role of cytokines in the body: Cytokines are small proteins that are crucial in controlling the growth and activity of other immune system cells and blood cells.

Identify the primary function of cytokines: They are involved in regulating immune responses, which includes signaling between cells to trigger inflammation, immune responses, and cell communication.

Differentiate cytokines from other biological molecules: Unlike DNA or RNA, cytokines do not store genetic information. They are not involved in the direct breakdown of carbohydrates or the transport of oxygen.

Consider the context of immune system regulation: Cytokines help in the activation and regulation of immune cells, such as T-cells and macrophages, which are essential for the body's defense mechanisms.

Conclude by matching the function to the options provided: The correct function of cytokines from the given options is 'Regulating immune responses.'
