The thyroid is a butterfly-shaped endocrine gland located below the Adam’s apple in the lower part of the neck that wraps around the windpipe (trachea).
The thyroid plays a role in a number of bodily functions, including:
- Metabolism of fats, carbohydrates, proteins, electrolytes, and water
- Metabolic rate (oxygen consumption)
- Growth and development
- Resistance to infection
- Vitamin requirements
- Reproduction
- Playing a role in metabolic rate
- Maintaining bone health
- Maintaining muscle control
- Preserving brain function and development
- Maintaining heart and digestive functions
