Question

When you run, you begin to breathe heavier and faster. Your heart beats
more quickly, bringing more oxygen to your cells. Which organ systems
are working together here?​

Answer 1

Answer:

When you are doing increased physical activity, such as cycling, running or climbing, your breathing becomes faster. As well as bringing oxygen into the body more quickly, this speeds up the process of getting rid of carbon dioxide. Your brain sends out instructions to your body to increase the rate of respiration.
