Our breathing rate increases and you start to breathe heavily, this happens because
More blood gets circulated around the body
We have started to perform a physical activity
To break down Lactic Acid and replenish energy supplies.
Our muscles need more oxygen so you breathe deeper and quicker so a supply of oxygen can get to the muscles.
What is the function of carbohydrate?
To keep the body warm
To give energy to the body
For growth and repair of the body
To keep the eyes healthy
