You task is to utilize the parts of a negative feedback system to create a flow chart showing how (1) one endocrine hormones elicits a change. (Reference chapter one if you need to)
Be sure to describe the role of the following factors:
Parathyroid hormone is an Endocrine hormone responsible for Calcium regulation in the blood stream.The following chart shows its action.
REGULATION OF BLOOD CALCIUM LEVEL BY PARATHYROID HORMONE
Decreased blood CALCIUM level
Sensed by PARATHYROID GLAND
Release of PARATHYROID HORMONE
-------------------------------------------------------------------------------------
BONES KIDNEYS
Release of CALCIUM into blood 1)Uptake of Calcium from Collecting tubules
2)Release of calcitriol INTESTINE
Increased CALCIUM absorption from food
Increases CALCIUM LEVEL IN BLOOD
-ve feedback
Sensed by PARATHYROID HORMONE
Decreases PARATHYROID production
