Regulation Of Pulmonary Ventilation During Exercise Flashcards
Three factors involved in the regulation of pulmonary ventilation during exercise
- Neural Control
- Chemical Control
- Hormonal Control
Neural Control involves the…
Brain and Nervous system
Nervous system controls pulmonary ventilation automatically through two systems…
Sympathetic and Parasympathetic
Chemical control is concerned with…
CO2 (high blood acidity)
When CO2 is high, the brain is informed and it sends the..
Respiratory control Centre
Respiratory control centre is made up of
Inspiratory and expiratory centres
Chemoreceptors
Detect chemical changes in the blood
Baroreceptors
Detect a change in blood pressure
Proprioreceptors
Detect muscle movement
Inspiratory centre sends and impulse through…
Phrenic Nerve
What does the Phrenic Nerve do?
Stimulates inspiratory muscles for faster breathing
External intercostals, diaphragms, scalenes, sternocleidomastoids, pectoralis major
Expiratory centre sends nerve impulses to the…
Intercostal nerve
What does the intercostal nerve do?
Stimulate expiratory muscles for faster exhalation
Abdominals, Internal intercostals
