- Movement. -Includes moving from place to place(but not all living things have the ability to move)
- Responsiveness.
- Metabolism (includes digestion)
- Excretion.
- Reproduction.
- Growth.
What are the 4 necessary life functions?
The basic processes of life include organization, metabolism, responsiveness, movements, and reproduction. In humans, who represent the most complex form of life, there are additional requirements such as growth, differentiation, respiration, digestion, and excretion. All of these processes are interrelated.
What is not necessary for maintaining life?
The maintenance function of living organisms must go on even when they are not doing anything particular. The various processes essential for maintaining life are nutrition, respiration, transportation, excretion, control and coordination. In absence of any one of these, the life become, difficult.
Is water a necessary life function?
Water’s extensive capability to dissolve a variety of molecules has earned it the designation of “universal solvent,” and it is this ability that makes water such an invaluable life-sustaining force. On a biological level, water’s role as a solvent helps cells transport and use substances like oxygen or nutrients.

What are the 9 necessary life functions?
Like all complex animals, humans must maintain a core set of necessary life functions to survive. These include maintaining boundaries, movement, responsiveness, digestion, metabolism, excretion, reproduction, and grow.
What are the 12 life functions?
September 12, 2017 Life processes are biological/cellular activities that maintain homeostasis, keep the organism alive and propagate the species. The life processes are metabolism, nutrition, transport, cellular respiration, synthesis, excretion, regulation, growth & development and reproduction.
What are the 5 functions of water?
Water: Essential to your body
- Regulates body temperature.
- Moistens tissues in the eyes, nose and mouth.
- Protects body organs and tissues.
- Carries nutrients and oxygen to cells.
- Lubricates joints.
- Lessens burden the on kidneys and liver by flushing out waste products.
Why do we need to maintain the necessary life functions?
Like all complex animals, humans must maintain a core set of necessary life functions to survive. These include maintaining boundaries, movement, responsiveness, digestion, metabolism, excretion, reproduction, and grow. In order to survive, humans also need nutrients, oxygen, water and an appropriate atmosphere.
Which is a necessary function of an organism?
necessary life functions (def, why) – 8 fns that must be maintained to support life. – whole science of physiology is based on how life is maintained. – internal environment from cells to the organism must be kept separate from the external environment—conditions for life are tightly balanced.
What does maintaining boundaries mean as necessary life function?
Define what Maintaining Boundaries means as a Necessary Life Function. The “inside” remains distinct from the outside. This applies to three separate levels of the body. Some organs are surrounded by a membrane, which protects them.
What are the 5 outside factors required for life?
Outside factors required for life Name the 5 Survival Needs. Nutrients (Food), Oxygen, Water, Appropriate Temperature, Atmospheric Pressure Define what Maintaining Boundaries means as a Necessary Life Function. The “inside” remains distinct from the outside. This applies to three separate levels of the body.

How does the human body provide the necessary environment for life?
The human body is 60-80% water. Water is the most abundant chemical substance in the body and provides the environment necessary for life. We obtain water through food and liquids and loose it through bodily excretions and evaporation (from the skin). Breathing and gas exchange in the lungs depend on the right type of atmospheric pressure.
