Answer 2

hello friend!
The heart needs the kidneys to constrict arterioles to maintain blood pressure and the kidneys need the heart to pump fluid for them to excrete. There is no one organ that is most important the body works together. But for the sake of amusement I would say the brain.

The number of muscles in our body varies from around 640 to 850.
