English to Persian (Farsi) Science Biology (-tech,-chem,micro-)

the organs and organ systems of the human body work together like a well-oiled machine. This is because
they are closely regulated by the nervous and endocrine systems. The
nervous system controls virtually all body activities, and the endocrine system secretes
hormones that regulate these activities. Functioning together, the organ
systems supply body cells with all the substances they need and eliminate their wastes. They also keep temperature,
pH, and other conditions at just the right levels to support life processes
