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

Ecology

 * Carbon respiration, a concept used in calculating carbon (as ) 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

Entertainment
