Why is the adrenal gland called an emergency gland and the 3F gland?
The adrenal called the gland of emergency because they release Adrenaline hormone which is called an emergency hormone, When adrenaline is secreted into the blood it prepares our body for action. It speeds up heartbeat and breathing, raises blood pressure, and allows more glucose(Carbohydrates) to go into the blood to give us a lot of energy quickly to run or fight. Additionally, it is secreted in the body when the body is under severe physical/emotional stress or depression. It helps us to deal with the emergency by generating more energy in the body, thatswhy Adrenaline is called an Emergency Hormone. And Adrenal glands are called Glands of Emergency.
Epinephrine is called the 3F (it makes fright, fight & flight) hormone, and the adrenal gland that produces this hormone is called the 3F gland.
