The biological definition of homeostasis is “the tendency of an organism or cell to regulate its internal environment and maintain equilibrium, usually by a system of feedback controls, so as to stabilize health and functioning”. Generally, the body is in homeostasis when it’s needs are met and it’s functioning properly.. 2 DIURETICS also known as 147WATER PILLS148 PURPOSES SPECIFIC MEDICATONS POSSIBLE HARMFUL EFFECTS PERSONAL EFFORTS TO ENHANCE THERAPY Increase salt sodium elimination by the kidneys Decrease leg lun Andrew .
