physiological functions

Physiological functions are the natural processes that occur within your body to keep you alive and healthy. These include essential activities like breathing, which brings oxygen in; circulation, which moves blood and nutrients throughout your body; digestion, which breaks down food for energy; and waste elimination, removing substances your body no longer needs. Other functions involve regulating body temperature, maintaining fluid balance, and supporting immune defense. Together, these processes work seamlessly to sustain life, support growth, and enable you to respond to your environment.
