Which is considered a high-priority health issue in the united states?
a. anorxia
b. autism
c. immunizations
d. dental health

My choice is letter c. immunization. It is the main concern of the U.S. to ensure that everyone is immunized from disease so that they are protected from diseases that could jeopardize their health.  It is especially true among children since they are most prone to catching diseases.

fluid balance is an aspect of the homeostasis of organisms in which the amount of water in the organism needs to be controlled, via osmoregulation and behavior, such that the concentrations of electrolytes (salts in solution) in the various body fluids are kept within healthy ranges. the core principle of fluid balance is that the amount of water lost from the body must equal the amount of water taken in.
