What is properties of endocrine control?Show answer
Compared with nervous control, hormonal control is slow to start, because the hormone must travel in the blood; widespread, because the blood reaches the whole body; and long-lasting, because hormones persist until broken down. The nervous system, by contrast, is fast, targeted and brief. Many homeostatic systems use both: the nervous system for the rapid initial response and the endocrine system for the sustained adjustment.
What is blood glucose regulation (the key WACE example)?Show answer
Blood glucose is controlled by two antagonistic hormones from the islets of Langerhans in the pancreas.
