what is anaerobic activity?
activity that requires energy to be produced without the use of oxygen to the muscles.

what is happening to the body?
cardiovascular system- refers to the heart and blood vessels which circulates blood around the body. the volume of blood being pumped changes during activity.

the respiratory system
refers to the lungs, and the muscles which control the thorax cavity that are attached to the rib cage. increasing lung capacity allows the body to intake oxygen and dispel carbon dioxide more quickly.
4 of 10
the circulation and respiration rates
controlled to ensure that the supply of oxygen and food, together with the removal of carbon dioxide, is maintained during exercise.
