The hormones testosterone, cortisol, and insulin are all classified as hormones that are secreted by glands directly into the bloodstream. Once released into circulation, these hormones travel at the speed of blood flow throughout the body.

Testosterone is produced by the testes in males and by the ovaries in females, and it plays a key role in the development of male characteristics as well as influencing various physiological functions in both sexes. Cortisol, produced by the adrenal glands, is crucial for regulating metabolism, the immune response, and assisting the body in responding to stress. Insulin, secreted by the pancreas, regulates blood glucose levels, allowing cells to absorb glucose for energy.

Since all three hormones are released directly into the bloodstream, they can rapidly circulate and exert their effects on target tissues. Therefore, the choice indicating that all of them travel at the speed of blood is indeed accurate.
