Hormones: Adrenaline and Thyroxine

The video explains the roles of two hormones: adrenaline and thyroxine. Adrenaline, produced by the adrenal glands, prepares the body for fight or flight by increasing heart rate, blood pressure, and blood sugar levels. Thyroxine, produced by the thyroid gland, regulates metabolic rate and is controlled by a negative feedback mechanism involving TRH and TSH. The video details how these hormones function and their effects on the body, emphasizing the importance of maintaining balance through negative feedback.
