The thyroid gland, a butterfly-shaped gland in the neck area regulates cellular metabolism. Its hormones--triiodothyronine or T3 and thyroxine or T4, acts on target tissues. They act on practically every cell in the body to increase metabolic rate and long bone growth, protein synthesis and metabolism of nutrients to obtain energy. This hormone leads to heat generation in humans therefore, its role affects body temperature. Iodine must be available in the bloodstream to produce thyroid hormones. Thyroid hormones affect the heart's output and heart rate, brain development in the young, the uterine lining in females during the menstrual cycle, breathing rate and metabolism. There is another hormone called calcitonin, acts on bones by enhancing calcium deposition into the bone, when blood levels of calcium are high.
The gland that regulates the body’s metabolism and energy consumption while also helping with bone construction and strength, is THYROID GLAND.
Basically thyroid gland are essential for cell functions, that produces hormones from iodine and stores them, in order to regulate growth and different chemical reactions in the body.
Thyroid gland is a part of endocrine system, whose function is to release hormones directly in the bloodstream of our body. Thyroid gland is in the shape of a butterfly, located in the lower part of the neck. It produces if hormones from iodine which is basically found in foods we have.
Thyroid gland performs a number of essential functions, some of them are as follows:-
- Regulates body's metabolism
- Helps in consuming energy
- Helps in growth and development of bones especially in young children
- Stimulates bones cells to add calcium to bones
- Essential in regulating heart rate and blood pressure
- Maintains body temperature
