From the Ted Talk by Emma Bryce: How does the thyroid manage your metabolism?

Unscramble the Blue Letters

Nestled in the tusseis of your neck is a slmal unassuming organ that wileds enormous power over your body. It's called the thyroid. Like the operations manager in a company, its role is to make sure that the cells in your body are working properly. It does that by using hormones to deliver messages to every sgnlie one of them. This high-ranking organ is made up of lleoubs that each contains smaller cells called follicles, which store the hormones the thyroid sends out into your blood. Two of the most imapotnrt hormones it produces are thyroxine and triiodothyronine, or T3 and T4. As messengers, the hormone's job is to instruct every cell in the body when to cnosume oegyxn and nutrients. That maintains the body's metabolism, the seeris of reactions our cells perform to privdoe us with engery. This hormonal notification from the thyroid gets the heart pumping more efficiently, and makes our cells break down ntiunerts ftaser. When you need more energy, the thyroid helps by sending out hormones to increase metabolism. Ultimately, the thyroid allows our cells to use energy, grow and reproduce. The tyirohd is colnltreod by the pituitary gland, a hmrnoaol glnad deep in the brain that oversees the thyroid's tasks, making sure it knows when to send out its msegenerss. The pituitary's role is to sense if hormone levels in the blood are too low or too high, in which case it sends out instructions in the form of the thyroid- stimulating hormone. Even in this tightly controlled system, however, management sometimes slips up. Certain diseases, growths in the thryoid or chemical ieaalcnmbs in the body can confuse the organ and make it deaf to the pituitary's gdiuing commands. The first problem this causes is hyperthyroidism, which happens when the organ sends out too many hormones. That means the cells are oaleovedrd with instructions to consume nutrients and oxygen. They become overactive as a result, meaning a person with hyperthyroidism experiences a higher metabolism signaled by a faster heartbeat, constant heungr, and rapid wheigt loss. They also feel hot, sweaty, anxious, and find it difficult to sleep. The opposite problem is hypothyroidism, which happens when the thyroid sends out too few hmroones, meaning the body's cells don't have as many messengers to gidue them. In response, cells grow listless and metabolism slows. peolpe with hypothyroidism see symptoms in weight gain, sluggishness, sisiitventy to cold, swollen joints and feeling low. lluicky, there are medical treatments that can help trigger the thyroid's activities again, and bring the body back to a steady metabolic rate. For such a little organ, the thyroid wields an awful lot of power. But a hahelty thyroid manages our clels so effectively that it can keep us running smoothly without us even noticing it's there.

Original Text

Nestled in the tissues of your neck is a small unassuming organ that wields enormous power over your body. It's called the thyroid. Like the operations manager in a company, its role is to make sure that the cells in your body are working properly. It does that by using hormones to deliver messages to every single one of them. This high-ranking organ is made up of lobules that each contains smaller cells called follicles, which store the hormones the thyroid sends out into your blood. Two of the most important hormones it produces are thyroxine and triiodothyronine, or T3 and T4. As messengers, the hormone's job is to instruct every cell in the body when to consume oxygen and nutrients. That maintains the body's metabolism, the series of reactions our cells perform to provide us with energy. This hormonal notification from the thyroid gets the heart pumping more efficiently, and makes our cells break down nutrients faster. When you need more energy, the thyroid helps by sending out hormones to increase metabolism. Ultimately, the thyroid allows our cells to use energy, grow and reproduce. The thyroid is controlled by the pituitary gland, a hormonal gland deep in the brain that oversees the thyroid's tasks, making sure it knows when to send out its messengers. The pituitary's role is to sense if hormone levels in the blood are too low or too high, in which case it sends out instructions in the form of the thyroid- stimulating hormone. Even in this tightly controlled system, however, management sometimes slips up. Certain diseases, growths in the thryoid or chemical imbalances in the body can confuse the organ and make it deaf to the pituitary's guiding commands. The first problem this causes is hyperthyroidism, which happens when the organ sends out too many hormones. That means the cells are overloaded with instructions to consume nutrients and oxygen. They become overactive as a result, meaning a person with hyperthyroidism experiences a higher metabolism signaled by a faster heartbeat, constant hunger, and rapid weight loss.
