Other systems interact with the digestive system to maintain homeostasis. one system moves food through the digestive system so that it can be broken down into nutrients through mechanical digestion. another system then delivers those nutrients from the digestive system to the rest of the body. select the two systems which are responsible for these interactions.
a
nervous

b
immune

c
muscular

d
excretory

e
respiratory

f
cardiovascular

D. Excretory and F. Cardiovascular

Excretory system checks the blood stream by filtering substances and eliminates unwanted compounds as urine. Water content of our body is maintained by kidneys.
