Respiratory physiology
From Wikipedia, the free encyclopedia
Respiratory physiology is the branch of human physiology focusing upon respiration.
Topics include:
Contents |
[edit] Volumes
- lung volumes
- vital capacity
- functional residual capacity
- dead space
- spirometry
- body plethysmography
- peak flow meter
[edit] Mechanics
- Anatomy: pleural cavity, thoracic diaphragm, Intercostales externi muscles, Intercostales interni muscles
- inhalation and exhalation
- lung, pulmonary alveolus
- With insufficient pulmonary surfactant, the pulmonary alveoli collapse, causing atelectasis (in infants, infant respiratory distress syndrome)
- the law of Laplace,
- compliance (physiology) - decreased with fibrosis, increased with emphysema[1]
- Poiseuille's law
- asthma and COPD
- hysteresivity
[edit] Circulation, ventilation, and perfusion
- pulmonary circulation
- positive pressure ventilation
- hypoxic vasoconstriction
- ventilation (physiology), perfusion, ventilation/perfusion ratio (V/Q), and ventilation/perfusion scan
- shunts: right-to-left (tetralogy of fallot), left-to-right (patent ductus arteriosus)
- respiratory rate and respirometer
[edit] Gas exchange/transport (primarily oxygen and carbon dioxide)
- gas exchange
- Dalton's law
- hemoglobin
- oxygen-haemoglobin dissociation curve, Bohr effect, Haldane effect
- carbonic anhydrase
- oxyhemoglobin
- respiratory quotient
- arterial blood gas
[edit] Control and response
- control of respiration
- reticular formation
- pons (apneuistic and pneumotaxic)
- chemoreceptors (medulla, carotid body, aortic body)
- Hering-Breuer reflex
- involuntary control of respiration
- exercise
- hyperoxia
- hypoxemia (hypoxic hypoxia)
[edit] Disorders
- altitude sickness
- asthma
- carbon monoxide poisoning
- COPD
- emphysema
- infant respiratory distress syndrome
- pulmonary edema
