Diabetes Insipidus
ADH V2 receptors on the kidneys collecting duct are defective; causes dehydration, growth delay and mental slowness; high caroirie diet and water help stop these symptoms
Diabetes Mellitius Type 2
"noninsulin-dependent"; cells lose insullin receptors; caused by over eating, lack of exercise or all around poor life style; common in over weight people; cure by healthy diet and exercise
Diabetes Mellitius Type 1
"juvenile-onset"; autoimmune; cells attack pancreatic beta cells; haults insullin secretion; 3x per day insullin shots
Endocrine Gland
a gland that secretes hormones directly into the blood or body fluid
Exocrine Gland
a gland that secretes its products into a duct or onto a body surface
a substances secreted by an endocrine gland that is transmitted in the blood or body fluid
Target Cells
a specific cell on which a hormone exerts its effect
a group of compounds that have powerful hormonelike effects
a type of endocrine secretion in which the hormone affects nearby cells
