In physiology, respiration involves transporting oxygen from the environment to cells in tissues and removing carbon dioxide via the respiratory system. This process differs from cellular respiration, which is a metabolic process producing energy within cells. Respiration includes ventilation—the movement of air during inhalation and exhalation—and perfusion, the blood flow in pulmonary capillaries. Air reaches the alveoli where gas exchange occurs. The lungs maintain a stable functional residual capacity of gases, ensuring homeostasis throughout the body. Although often used interchangeably, breathing and ventilation are technically hyponyms of respiration, with distinct physiological meanings.
Classifications of respiration
There are several ways to classify the physiology of respiration:
By species
By mechanism
By experiments
By intensive care and emergency medicine
- CPR
- Mechanical ventilation
- Intubation
- Iron lung
- Intensive care medicine
- Liquid breathing
- ECMO
- Oxygen toxicity
- Medical ventilator
- Life support
- General anaesthesia
- Laryngoscope
By other medical topics
- Respiratory therapy
- Breathing gases
- Hyperbaric oxygen therapy
- Hypoxia
- Gas embolism
- Decompression sickness
- Barotrauma
- Oxygen equivalent
- Oxygen toxicity
- Nitrogen narcosis
- Carbon dioxide poisoning
- Carbon monoxide poisoning
- HPNS
