Premium Hormone Endocrine system Hypothalamus
Endocrine Vs Nervous System The endocrine system acts with nervous system to coordinate the body’s activities. Both systems enable cells to communicate with others by using chemical messengers. The endocrine system uses chemical messengers called hormones that are transported by the circulatory system (blood). They act on target cells that may be anywhere in the body.

out via osmosis‚ which is determined by Antidiuretic Hormone secretion (3). Whether or not water needs to be conserved determines the amount of ADH that is released. If the hormone ADH is high‚ then the collecting duct becomes more permeable to water so more water is drawn out which means that less urine volume and it will be more concentrated. If ADH is low then less water is removed and the urine volume is large and more diluted. For the salt group‚ eating potato chips and drinking the salt solution
