THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -The volume of the lungs of women and children are smaller than that of lungs of men, therefore women and children have a slightly faster breathing rate.

Detailed explanation-2: -Rapid, shallow breathing is often referred to as tachypnea, which occurs when you take more breaths than usual in a given minute. This is usually defined as more than 20 breaths per minute in an adult. In children, the number of breaths per minute can be a higher resting rate than seen in adults.

Detailed explanation-3: -It is well established that women experience greater shortness of breath during physical activity, from stair climbing to long-distance running, than men of a similar age. This is true in healthy young and older adults, as well as in patients with chronic heart and lung disease.
