Cytokines are frequently used by immune system cells to communicate with one another.
<h3>What impact do cytokines have on the body?</h3>
- Small proteins called cytokines play a key role in regulating the development and activity of blood and immune system cells.
- They stimulate the immune system to function once they are released.
- All blood cells as well as other cells that support the body's immunological and inflammatory responses are affected by cytokines.
<h3>What creates cytokines in the body?</h3>
- Many different cell types create cytokines, although helper T cells (Th) and macrophages are the main producers.
- By resident and migrating macrophages, mast cells, endothelial cells, and Schwann cells during normal and pathological processes, peripheral nerve tissue may create cytokines.

Explanation:
Answer:
Homologous structures provide evidence for common ancestry analogous structures show that similar selective pressures can produce similar adaptations beneficial features Similarities and differences among biological molecules in the DNA sequence of genes can be used to determine species relatedness
