What role do endocrine glands play during development?

Endocrine glands are crucial during development because they secrete hormones directly into the bloodstream, which play a vital role in regulating growth and maturation processes. During different stages of development, hormones such as growth hormone, thyroid hormones, and sex hormones influence various aspects of physical growth, metabolism, and the maturation of organs and systems. For instance, growth hormone encourages the growth of bones and tissues, while sex hormones are essential for the development of secondary sexual characteristics during puberty. This hormonal regulation ensures that development occurs in a coordinated and timely manner, allowing an organism to transition through different life stages effectively.
