The Human Hormones Quiz – Chemical Messengers

Hormones are chemical messengers made by glands of the endocrine system and carried in the blood to target organs. They control growth, metabolism, sleep, mood, reproduction and how the body handles stress.

Key glands include the pituitary, often called the master gland, the thyroid in the neck, the adrenal glands on the kidneys and the pancreas, which makes insulin to control blood sugar. The pineal gland releases melatonin to help regulate sleep.

Hormone imbalances can cause conditions like diabetes or thyroid disorders. The discovery of insulin in 1921 saved millions of lives, and today many hormone conditions can be treated effectively.
