Description

For engine power and endurance, nothing beats the human heart. Over a 12-hour period it propels enough blood to fill 22,132 wine glasses. The human chassis isn't bad, either. Its bones are ultra-light and tough as steel, not to mention that they produce 139 million blood cells every minute. Using animation and dramatizations, this program offers up surprising and enlightening facts about the body's hard-driving machine. It reveals the amazing capacity of our lungs, which, in half a day, pump enough air to fill almost 4,000 balloons; the tug-of-war dynamism of human musculature, our anatomical transmission system; and the rapid-fire mobility of jaw and eye structures-including our "windshield wipers," which blink 415 million times over an average life.
