The release of ACTH from the anterior lobe of the pituitary gland causes the _______.

Front 5

When blood glucose levels are high

Back 5

The pancreas responds to high blood glucose levels by releasing insulin.

decrease the amount of water lost at the kidneys.

Front 15

The hypothalamus controls secretion by the adenohypophysis by
