Life processes


Life processes are the fundamental activities of living organisms necessary for their growth, survival, and reproduction. Irrespective of whether a life-form is a plant, animal, bird, and microorganism, life processes exist, however they vary in each type of organism. For instance, the process of digestion in a plant differs from animals.   All living organisms must perform certain life processes like growth and development, digestion, excretion, respiration, circulation, etc. Life processes will ensure the organisms to live a balanced life. Some of the common life processes are digestion, respiration, excretion, nutrition, locomotion, growth and development, reproduction, regeneration, maintenance, and repair.



Why do we need maintenance processes?

Life processes are continuous and cyclic processes happen progressively throughout the life. Some of the common life processes include metabolism, respiration, transportation, digestion and excretion, growth and development and reproduction. Life processes help in the maintenance and regulation of the body hence, they re also known as maintenance processes. If our body fails to maintain its activities, it results in sickness and death. In order for the maintenance process to continue, energy is vital. The energy formation itself a cycle. In order to keep the body clean and free from waste material, excretion is vital, it is also an important process essential for survival. Every life process demands raw materials such as carbon, nutrients, minerals, water, hormones etc. The following links will take you to the individual life processes that are significant in life.


Common  life processes:

  1. Digestion( Read main article Digestion as a life process in human beings)

  2. Read Respiration as a life process here

  3. Excretion - a life process

  4. Nutrition( Read plant nutrition here)

  5.  Transportation( circulation)  as a life process( read about blood and circulatory system here)

  6. Growth and Development as a life process

  7. Reproduction( Also read Introduction to human reproduction here )

  8. Tissue Regeneration, Maintenance, and Repair as the life processes.
