Although the digestive system is primarily
responsible for the breakdown of food, this
process can be disrupted if the circulatory
system malfunctions. the best explanation for
this disruption is that
(1) human body systems interact with each
other to perform life functions
(2) the circulatory system is the control center of
the body
(3) the digestive system and the circulatory
system have many organs in common
(4) the circulatory system is responsible for the
coordination of life functions, including the
breakdown of food
