Secretin
When blood glucose levels are low
The pancreas releases glucagon, which eventually causes blood glucose levels to increase
When blood glucose levels are high
The pancreas responds to high blood glucose levels by releasing insulin.
Why don't all body cells respond to a particular hormone? -The liver removes the hormone before all cells can be exposed. -All body cells aren't exposed to the hormone. -Only cells that have receptors for the hormone can respond. -Glands don't secrete enough hormone to affect all body cells.
-Only cells that have receptors for the hormone can respond.
Which of these occurs when blood glucose concentration falls below the normal range? -The pancreas secretes insulin. -The pancreas secretes glucagon. -The adrenal gland secretes aldosterone. -The thyroid gland secretes thyroxine.
