True or False: Hormones circulate to all tissues and can influence all cells.

The correct consideration is that hormones indeed circulate throughout the body and have the potential to interact with a wide range of tissues and cells. However, not every hormone influences every cell in the body. The action of hormones is specific to particular cells that express the receptors compatible with those hormones. For instance, insulin primarily acts on liver, muscle, and fat cells due to the presence of insulin receptors on those cells, meaning that while insulin travels the bloodstream, its effects are not universal among all cells. Thus, hormones do not influence every cell indiscriminately, supporting the idea that it is more accurate to state that the influence of hormones is selective rather than universal. This specificity means that the assertion is false, leading to the choice that indicates false as the correct answer.
