The Endocrine System
Thyroid Gland
-
Hormones
Thyroxine.
-
There is no one target organ, all organs respond.
-
-
-
Pancreas
The pancreas is located across the back of the abdomen, behind the stomach. It is a mixed type of gland that shows both endocrine and exocrine functions.

The adrenal glands are small yellow masses of tissue that lie in contact with the upper ends of the
kidneys. It has two parts:
-
-
-
Parathyroid Gland
-
-
Antagonistic Mechanism
-
-
-
-
Parathormone:stimulates Ca uptake in kidneys. Calcitonin: decreases the resorption of calcium in kidneys.
Antagonistic Mechanism
-
-
-
Insulin: increases the permeability of cells to take glucose Glucagon: conservation of glycogen to glucose into liver.
