HARMONES and their functions Hormones are chemical messengers produced by various glands in the body that help regulate and coordinate the activities of different cells, tissues, and organs. They play a crucial role in maintaining overall homeostasis and controlling various physiological processes. Here are some important hormones and their functions: ▪️Insulin: Produced by the pancreas, insulin regulates the metabolism of carbohydrates, fats, and proteins. It helps lower blood glucose levels by facilitating the uptake of glucose into cells. ▪️Glucagon: Also produced by the pancreas, glucagon works in opposition to insulin. It raises blood glucose levels by stimulating the breakdown of glycogen into glucose in the liver, a process called glycogenolysis. ▪️Thyroid hormones (T3 and T4): Produced by the thyroid gland, these hormones regulate metabolism, growth, and development in the body.
