What is the thyroid gland?

The thyroid gland is a small butterfly-shaped gland located at the base of the neck just below the center of the throat. It is part of a complex network of glands called the endocrine system. The endocrine system is responsible for coordinating many activities in the human body. The thyroid gland produces hormones that regulate the metabolism of the human body.

The thyroid gland is the largest gland in the neck. It is butterfly-shaped and has two lobes (one on each side of the neck). The entire structure is about two inches long, located just below the Adam's apple.

Glands are endocrine and exocrine. Because the thyroid works by secreting hormones directly into the bloodstream, it is considered our main endocrine gland and a key part of the entire endocrine system. The thyroid gland needs iodine to function, which it uses to make the thyroid hormones thyroxine (T4) and triiodothyronine (T3).

Blood circulates in the human body, one of the functions of which is to supply body cells with oxygen. Red blood cells called erythrocytes do this. They contain iron, thanks to which oxygen is transported.

Without enough iron, red blood cells will not be able to carry enough oxygen. However, too much iron is not good for the human body either. Both high and low iron levels can indicate a serious illness.

Ferritin is a blood protein that stores iron. Think of your body as a kitchen pantry. Most of the pantry is filled with food that you consume every day. But there are some things you keep in there for the long haul—an extra box of pasta or can of beans to have on hand when supplies run low.
