When water levels in the body get too low and the body becomes dehydrated, the pituitary gland releases a hormone called anti- diuretic hormone (ADH). ADH signals to the kidneys to reduce the amount of water exiting the body in urine. With the loss of fluid
volume the blood pressure can drop, so ADH (also called vasopressin) causes the blood vessels to constrict resulting in an increase in
blood pressure. In this process, during periods of dehydration, which body system is NOT involved in maintaining the homeostatic
balance of fluid volume?
A)
Circulatory
B)
Endocrine
Excretory
D)
Muscular
