The more intense the exercise, the greater the concentration of CO2 in the blood
True
To combat this, your breathing rate increases to ensure CO2 can be breathed out
Anticipatory breathing rate increases
Capillary network surrounding the alveoli expands
This increases blood flow to the lungs and pulmonary diffusion
The respiratory centers of the brain send impulses to the respiratory muscles to control breathing frequency and tidal volume of each breath
When you start exercising what happens to your respiratory system?
Tidal volume : the amount of air you breathe in and out with each breath
Pulmonary Ventilation: The amount of air we breathe in and out per minute
Pulmonary Ventilation= Frequency X Tidal Volume
True or False
Breathing
Inspiration
