Outline the four main organs of the endocrine system?

1. Pituitary gland: Often referred to as the "master gland," the pituitary gland is located at the base of the brain and is responsible for regulating the function of other endocrine glands in the body. It produces and releases hormones that control various bodily functions, including growth, metabolism, and reproduction.

2. Thyroid gland: Located in the neck, the thyroid gland produces hormones that regulate metabolism, energy levels, and growth. It plays a crucial role in maintaining the body's overall balance of hormones.

3. Adrenal glands: Situated on top of the kidneys, the adrenal glands produce hormones such as cortisol and adrenaline that help the body respond to stress, regulate blood pressure, and maintain fluid balance.

4. Pancreas: In addition to its role in digestion, the pancreas also plays a key role in the endocrine system by producing insulin and glucagon, which help regulate blood sugar levels. These hormones are essential for maintaining proper energy levels and preventing conditions such as diabetes.
