Necessary Life Functions at Life

Necessary Life Functions. The different organ systems each have different functions and therefore unique roles to perform in physiology. Break down complex molecules into smaller ones.

Living organisms are systems made from cells and are capable of life functions such as reproduction, metabolism, response to stimuli, and homeostasis. A state of change all chemical reactions that occur in within the body cells. We can then, by the process of respiration, use the energy in these nutrients for such vital functions as growth and repair of body parts.

Breaking down of ingested foodstuffs to simple molecules can be absorbed into the blood. Maintain boundaries, movement, responsiveness, digestion, metabolism, excretion, reproduction, and growth. Build larger molecules from smaller ones. The absorbed substances circulate throughout the internal environment of our bodies.
