Examples include the heart, lungs and liver. : alveolus) before being expelled from the lungs when the diaphragm contracts again. The body varies anatomically in known ways. Survival depends on the body's maintaining or restoring homeostasis, a state of relative constancy, of its internal environment. From here, the blood is pumped into the lungs where it receives oxygen and drains back into the left side of the heart.

What is left is called chyme; this then moves into the small intestine, which absorbs the nutrients and water from the chyme. It then travels to the atrioventricular node which makes the signal slow down slightly allowing the ventricles to fill with blood before pumping it out and starting the cycle over again. Together, these systems regulate the internal environment of the body, maintaining blood flow, posture, energy supply, temperature, and acid balance (pH).[63].
