  • 1. Chapter 11 Presentation: The Endocrine System and Hypercalcemia Michaelia Fosses Summer 2012
  • 2. Endocrine System• The collection of glands in the endocrine system secrete hormones into the bloodstream• This is in contrast to the exocrine system, which secretes fluids into a duct• Hormones are chemicals secreted by a gland to control the function of a target tissue
  • 3. Endocrine System• Hormones are secreted into the bloodstream and work on a target organ or tissue, increasing or decreasing its activity level• The endocrine system maintains homeostasis in the body—a stable internal environment
  • 4.

  • 6. Hypercalcemia - Causes• Hypercalcemia can have several causes• Certain types of cancer can cause hypercalcemia• Primary hyperparathyroidism can cause hypercalcemia through excessive secretion of parathyroid hormone (PTH), which increases blood calcium levels
  • 7. Hypercalcemia – Diagnosis/Treatment• Diagnosis of hypercalcemia is made by checking blood calcium levels• Treatment of the hypercalcemia is done to return calcium to a safe level• Treatment of the cause of the hypercalcemia depends on the cause
