PATHOLOGY

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: -It is often suggested that when standing, vital capacity is greater and breathing movements more free than when sitting i.e. that during inspiration particularly, they require less effort (Steenstrup 2004).

Detailed explanation-3: -The body’s muscles and nervous system help control your breathing.
