What are the 3 functions of the thyroid gland?
What does the thyroid gland do? The thyroid gland produces hormones that regulate the body’s metabolic rate controlling heart, muscle and digestive function, brain development and bone maintenance. Its correct functioning depends on a good supply of iodine from the diet.
What does lack of thyroid do?
Hypothyroidism is a common condition where the thyroid doesn’t create and release enough thyroid hormone into your bloodstream. This makes your metabolism slow down. Also called underactive thyroid, hypothyroidism can make you feel tired, gain weight and be unable to tolerate cold temperatures.
How does the thyroid affect the body?
Your thyroid gland produces two main hormones, thyroxine (T4) and triiodothyronine (T3), that influence every cell in your body. They maintain the rate at which your body uses fats and carbohydrates, help control your body temperature, influence your heart rate, and help regulate the production of protein.
What are the signs that your thyroid is not working?
Symptoms. A person with mild hypothyroidism might feel fine and have no symptoms. But those with symptoms can experience a puffy face, sluggishness, weight gain, feeling cold, a slowed heart rate, constipation, depression, and thinning hair.
How does the thyroid gland work with other glands?
The thyroid releases them into your bloodstream, which takes them through your body. Another gland, called the pituitary gland, tells your thyroid how much of these hormones your body needs. Sometimes, the thyroid gland develops a problem. It might start producing too much or too little hormone.
What are the thyroid hormones?
The thyroid gland regularly secretes “thyroid hormones” that influence different aspects of the body. The “thyroid hormones” consist of triiodothyronine (T3), tetraiodothyronine (thyroxine or T4), calcitonin. The pituitary gland is responsible for triggering a response from the thyroid.
What is the function of the lobe of the thyroid?
Each lobe is filled with follicles that contain hormones the body needs to function. Two capsules surround the thyroid gland—an outer layer that connects to the voice box muscles and surrounding nerves, and one in between this layer and the thyroid gland that allows the thyroid to move when swallowing or talking. 1
How does the thyroid gland affect my metabolism?
The thyroid sits just below your voice box (larynx), near the base of your neck. Two hormones made by the thyroid gland help regulate your metabolism — the chemical processes in your body that break down what you eat to make energy. They can affect how fast your heart beats, how deep you breathe, and whether you gain or lose weight.
