Respiration

Respiration may refer to:

Biology

Cellular respiration, the process in which nutrients are converted into useful energy in a cell
- Anaerobic respiration, cellular respiration without oxygen
- Maintenance respiration, the amount of cellular respiration required for an organism to maintain itself in a constant state
Respiration (physiology), transporting oxygen and carbon dioxide between cells and the external environment
- Respiratory system, the anatomical system of an organism used for respiration
- Breathing, passing air in and out through respiratory organs
- Aquatic respiration, animals extracting oxygen from water
- Artificial respiration, the act of simulating respiration, which provides for the overall exchange of gases in the body by pulmonary ventilation, external respiration and internal respiration
- Cheyne–Stokes respiration, an abnormal pattern of breathing characterized by progressively deeper and sometimes faster breathing, followed by a gradual decrease that results in a temporary stop in breathing called an apnea
Respiration, a journal by Karger Publishers

Carbon respiration, a concept used in calculating carbon (as CO₂) flux occurring in the atmosphere
Ecosystem respiration, measurement of gross carbon dioxide production by all organisms in an ecosystem
Root respiration, exchange of gases between plant roots and the atmosphere
Photorespiration, enzymatic combination of RuBP with oxygen
