MEDICAL PHYSIOLOGY

Detailed explanation-1: -When you exercise and your muscles work harder, your body uses more oxygen and produces more carbon dioxide. To cope with this extra demand, your breathing has to increase from about 15 times a minute (12 litres of air) when you are resting, up to about 40–60 times a minute (100 litres of air) during exercise.

Detailed explanation-2: -Whatever your age, there’s strong scientific evidence that being physically active can help you lead a healthier and happier life. People who exercise regularly have a lower risk of developing many long-term (chronic) conditions, such as heart disease, type 2 diabetes, stroke, and some cancers.
