At each breath, air is drawn into more than
1,500,000 little air-sacs in the lungs, which if spread
out would cover an area of some 200 square
yards—the size of a nice little vegetable plot. These
little balloon-like sacs are made of a thin elastic
tissue which allows air to pass through but prevents
blood from oozing in.
The blood is carried to the lungs through
50,000,000,000 tiny hair-thin tubes which form a
close network all along the outside of the little
balloons of the lungs. Each day they bring in some
10,000 litres of blood. Oxygen is sucked in by the
red blood cells, while waste products of the body
like carbon dioxide and water are given up by the
blood, pass into the little air sacs, and are breathed
out.
As long as a child is in the womb of its mother its
lungs do not function, and the flow of blood is
turned away from the lungs by means of a special
little door in the heart. As soon as it is born, the
baby, who is on the verge of suffocation, utters a
loud cry. The cry produces a whole series of
wonderful changes. The great bags of the lungs
