HOSA Endocrine - Secretions of the Thyroid, Parathyroid, Thymus and Pancreatic gland

Thyroxine (T4) and Triiodothyronine (T3)

the two primary thyroid hormones that regulate the rate of metabolism and affect the growth and rate of functions of many other body systems

Calcitonin

produced by the thyroid gland and works with the parathyroid hormone to decrease calcium levels in the blood and tissues by moving calcium into storage in the bones and teeth

Parathyroid Hormone (PTH)

works with the hormone calcitonin that is secreted by the thyroid gland to regulate calcium levels in blood and tissues

Thymosin

Plays an important part in the immune system by stimulating the maturation of lymphocytes into T cells

Glucose

The basic form of energy used by the body

Glucagon

secreted by the alpha cells of the pancreatic islets in response to low levels of glucose in the bloodstream, increases the glucose level by stimulating the liver to convert glycogen into glucose for release into the bloodstream

Insulin

secreted by the beta cells of the pancreatic islets in response to high levels of glucose in the bloodstream
