NATURE AND SCIENCE SPEAK ABOUT GOD

Nature and Science Speak about God ~ 126 ~ 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.
