Indicate whether the statement is true or false.
____ 1. The endocrine system is a ductless system.
____ 2. Hormones are chemical messengers that are secreted directly into the bloodstream.

____ 10. Giantism results from a lack of somatotropin.
____ 11. An increased secretion of antidiuretic hormone causes diabetes insipidus.
____ 12. A goiter is an enlargement of the parathyroid gland.
____ 13. Hyperparathyroidism results in hypercalcemia, which leads to renal calculi.
____ 14. The symptoms of Cushing’s syndrome include hyperglycemia, hypertension, muscle weakness, a “moon” face, and obesity.
____ 15. Type 1 (IDDM) diabetes mellitus is the mature-onset form of diabetes and frequently occurs in obese adults.
____ 16. Researchers have proven that weight control and moderate exercise can reduce the risk of developing diabetes by as much as 55 to 70 percent.
____ 17. The thymus activates cells in the immune system early in life.
____ 18. Hyperparathyroidism is treated with calcium, vitamin D, and parathormone.
____ 19. Dwarfism is characterized by small body size, short extremities, lack of sexual development, and mental retardation.
____ 20. Symptoms of diabetes include polyuria, polydipsia, hypoglycemia, weight gain, and fatigue.
