Regulation Of Respiration Flashcards
What maintains the adequate amount of oxygen, carbondioxide and pH in blood?
The nervous system
What are the elements of the control system
Sensor(chemoreceptors, lungs)
Central controller(Medulla, pons)
Effector(Respiratory muscles)
What are the two distinct mechanisms in neural control?
Voluntary and automatic
Voluntary control of respiration is controlled by?
Automatic control of respiration is by?

Apneustic Centre is located on lower pine. T/F
True
The pneumotaxic Centre is located in the upper part of the pons. T/F
True
Function of the autonomic neural regulation is?
