1. regulates the body
using hormones: Endocrine
2. a signal initiates the
contraction of a muscle
a reflex causes the body
to move in response
to a stimulus: Neural control
3. vasopressin acts on renal
cells to maintain the body's
water and salt balance: Endocrine
4. aldosterone causes the
kidneys to reabsorb water: Endocrine
5. regulates the body using
electrical signals: Neural control
here are two definitions to help out
Endocrine system : The endocrine system is a chemical messenger system consisting of hormones, the group of glands of an organism that secrete those hormones directly into the circulatory system to regulate the function of distant target organs, and the feedback loops which modulate hormone release so that homeostasis is maintained. Example, water balance, bladder
Neural control has to do with signals
