* Estrogen and progesterone: These hormones are produced by the ovaries in women and are responsible for regulating the menstrual cycle and fertility.
* Testosterone: This hormone is produced by the testes in men and is responsible for regulating male characteristics, such as muscle mass and facial hair.
* Insulin: This hormone is produced by the pancreas and is responsible for regulating blood sugar levels.
* Thyroid hormone: This hormone is produced by the thyroid gland and is responsible for regulating metabolism.
* Growth hormone: This hormone is produced by the pituitary gland and is responsible for regulating growth and development.
* Adrenaline: This hormone is produced by the adrenal glands and is responsible for preparing the body for fight or flight.
* Cortisol: This hormone is also produced by the adrenal glands and is responsible for regulating stress responses.
Hormones work by binding to receptors on cells and then triggering a cascade of events that leads to a specific biological response. For example, when estrogen binds to receptors on cells in the uterus, it causes the cells to grow and thicken, preparing the uterus for pregnancy.
Hormones play a vital role in maintaining homeostasis in the body and regulating a wide range of functions, from metabolism to reproduction. When hormones are out of balance, it can lead to a variety of health problems, such as infertility, diabetes, and thyroid disease.
