There are several key hormones that play important roles in the body:
Estrogen: This hormone is primarily associated with the development of female sexual characteristics and the regulation of the female reproductive system.
Testosterone: Known as the male sex hormone, testosterone is responsible for the development of male reproductive tissues and the maintenance of male secondary sexual characteristics.
Insulin: Insulin helps regulate blood sugar levels and facilitates the uptake of glucose by cells for energy production.
Thyroidhormones: These hormones, including thyroxine (T4) and triiodothyronine (T3), regulate metabolism and influence growth and development.
Adrenaline (epinephrine) and noradrenaline (norepinephrine): These hormones are involved in the body's "fight or flight" response, increasing heart rate and mobilizing energy in times of stress.
Progesterone: Progesterone plays a key role in the menstrual cycle and pregnancy, as well as in the development of the mammary glands.

Hormonal factors have a wide range of functions in the body, including:
History and Nature of Science: A student should understand the history and nature of science. A student who meets the content standard should:
Develop an understanding that historical perspectives of scientific explanations demonstrate that scientific knowledge changes over time, building on prior knowledge.
Develop an understanding that scientific knowledge is ongoing and subject to change as new evidence becomes available through experimental and/or observational confirmation(s).
