The thyroid gland is an endocrine gland located at the base of your neck.
It is responsible for producing and releasing hormones which keep your metabolism under control and regulate different body functions, including body temperature, body weight, skin integrity, heart rate, breathing, cholesterol levels, muscle strength, menstrual cycle, and central and peripheral nervous system.
How the Thyroid Gland Works
It is well known that the thyroid is a component of the endocrine system. This system consists of glands responsible for producing, storing, and releasing hormones in the blood, allowing them to reach the cells in our body.
This gland uses iodine from food sources in order to produce Triiodothyronine (T3) and Thyroxine (T4).
The hypothalamus is responsible for producing TSH, a hormone which signals the pituitary to tell the thyroid to produce less or more of T3 and T4. To put it simply, it maintains a balance between T3 and T4.
Therefore, when there are low levels of T3 and T4 in the blood, the pituitary gland produces more THS in order to stimulate the production of more thyroid hormones.
If there are high levels in the blood, the pituitary gland releases TSH to the thyroid, which in turn slows down the production of thyroid hormones.
