juin [17]

Thyroid hormones regulate basal metabolic rate.

  • The hormone known as thyroid hormone regulates your body's metabolism, or how your body turns the food you eat into energy.
  • Thyroxine (T4) and triiodothyronine (T3), the two primary hormones your thyroid secretes, together make up thyroid hormone.
  • The thyroid gland creates hormones that control the body's metabolic rate, which affects bone growth and maintenance, heart, muscle, and digestive function.
  • Thyroid hormones regulate the amount of energy expended during activity to the extent that people with thyroid disorders exercise more or less.
  • They also have a direct impact on the basal or resting metabolic rate in humans and a permissive effect on small animals' adaptive thermogenesis.
