Volition: (Conscious Control)
- Breathing control during physical activities such as singing, swallowing or swimming is very important.
- Voluntary breathing control is limited. When oxygen supply in blood is getting low or our blood pH is falling, our respiratory centers will ignore messages from the cortex, or what we are trying to tell our body to do.
- Toddlers may try to manipulate their parents by holding their breath. Even though parents may worry about this, they don't need to because the involuntary controls will take over and begin again.
