Question

When you are climbing a hill, you begin to breathe quicker.How is it regulated?

Answer 1

because oxygen decreases as a result the blood veins burst because of high pressure so it is usually adviced to carry oxygen cylinder

Answer 2

When you are doing increased physical activity, like climbing a hill, your breathing becomes faster.

This brings oxygen into the body more quickly, and speeds up the process of getting rid of carbon dioxide. Your brain sends out instructions to your body to increase respiration rate.

This causes the excess carbon dioxide to be more quickly removed from the blood through the lungs. Once normal levels are reached, your breathing again becomes normal.
