Functions of the organs / organ system in our body must be coordinated to maintain ____
Homeostasis
_____is the process through which 2 OR MORE ORGANS INTERACT AND COMPLEMENT THE FUNCTIONS OF ONE ANOTHER .
Coordination
What happens when we do physical exercise ?
The energy demand is increased for maintaining an inc muscular activity —>supply of oxygen is also inc ->which necessitates an inc in the rate of respiration , heart beat ,and inc flow of blood via blood vessels
In our body , the _____and ____ jointly coordinate and integrate al the activities of the organs so that they function in a synchronised fashion .
Neural system Endocrine system
The ____provides an organised network of point-to-point connections for quick coordination .
Neural system
