In biochemistry, respiration may refer to:

• Cellular respiration, the process in which the chemical bonds of energy-rich molecules such as glucose are converted into energy usable for life processes
• Anaerobic respiration, a process that allows respiration without use of oxygen
• Plant respiration, the enzymatic oxidation of substrates in plants, leading to the release of carbon dioxide respiration.

In physiology, respiration may refer to :

• Respiration (physiology), the process by which multicellular organisms capture and excrete the gaseous fuel and waste of cellular respiration, absorbing oxygen and disposing of carbon dioxide.
  • Aquatic respiration, the process whereby an aquatic animal obtains oxygen from water
  • External respiration, the process by which gases are exchanged between the atmosphere and the pulmonary loop of circulation
  • Muscles of respiration
  • Respiratory system of humans and other mammals
  • Respiratory tract in humans is the part of the anatomy that has to do with the process of (physiological) respiration
  • Respiratory rate
  • Agonal respiration
  • Apneustic respirations
  • Cheyne-Stokes respiration
  • Biot's respiration
  • Respiratory arrest, the cessation of the normal tidal flow of the lungs due to paralysis of the diaphragm
  • Hypoventilation (also known as respiratory depression) occurs when ventilation is inadequate to perform needed gas exchange
  • Inspiratory paroxysmal respiration (also known as "reverse sneezing"), a phenomenon observed in dogs (Especially small dogs)

Medical devices involving respiration include:

• Respiratory therapy or Inhalation therapy, the assessment and treatment of respiratory and cardiovascular pathologies
• Artificial respiration
• Respirator

Other uses include:

• Carbon respiration, a phrase used in combination with carbon storage to calculate the amount of carbon (as CO2) flux occurring in the atmosphere through the various processes that add and subtract atmospheric carbon
• Respiration rate, a parameter which is used in ecological and agronomical modelling
