In humans and other vertebrates, certain processes are considered critical for sustaining life. These include respiration, nutrition, digestion, excretion, reproduction and metabolism.
- Respiration is one of the important life processes required for sustaining life. It involves the production of energy through the intake of oxygen and the release of CO2.
- Nutrition is another life process that is concerned with obtaining food for growth and repair.
- Digestion is concerned with processing and extracting the nutrients from the consumed food.
- Excretion is a life process that is concerned with expelling undigested and toxic end products from the body.
- Reproduction is the most important life process as it is concerned with the continuation of species.
- Metabolism is another type of life process concerned with various chemical processes important for life.
