Adrenaline and Thyroxine: Hormones and their Effects on the Body

The video explains the roles of adrenaline and thyroxine, two important hormones in the body. Adrenaline, produced by the adrenal glands, prepares the body for fight or flight during stress by increasing heart rate and boosting oxygen and glucose delivery. Thyroxine, produced by the thyroid gland, regulates basal metabolic rate and supports growth and development. The video also covers the negative feedback mechanism that maintains thyroxine levels, involving the pituitary gland and TSH. The session concludes with a recap of these key points.

What happens to adrenaline levels once the perceived danger is over?

Describe the process of negative feedback in relation to thyroxine levels.
