Movement
When an organism produces new body materials faster than old ones are worn out, the process is called?
Growth
The movement of substances within the body within body fluids is:
Circulation

Heat
Which of the following is a cooling process?
Sweating
Homeostasis in a healthy person
changes around the set point
