Identify the Principal Actions of the Hormones of the Thyroid

Question

Examlex · Accepted Answer

The Answer is The principal actions of the hormones of the thyroid and parathyroid glands are as follows:

Thyroid hormones, including thyroxine (T4) and triiodothyronine (T3), play a crucial role in regulating the body's metabolism. They increase the body's metabolic rate, promote growth and development, and help regulate body temperature. Thyroid hormones also play a role in the function of the cardiovascular system, nervous system, and reproductive system.

Parathyroid hormone (PTH), produced by the parathyroid glands, helps regulate the levels of calcium and phosphorus in the body. PTH increases the levels of calcium in the blood by stimulating the release of calcium from the bones, increasing the absorption of calcium from the intestines, and reducing the excretion of calcium by the kidneys. This helps to maintain the proper balance of calcium in the body, which is essential for bone health, muscle function, and nerve transmission.
