The human body is for all practical purposes infinitely more complex and efficient than anything ever built by man. You name it: a Cray Super-Computer, the Space Shuttle, an atomic reactor; these systems are super simple and utterly inefficient when compared to the human body.
An adult body consists of: 100 trillion little machines called cells, 206 bones, 600 muscles, and 22 internal organs. The largest organ is your skin. Every square inch that covers your body is made up of about 19 million skin cells. Approximately 1 billion cells are replaced every hour as your DNA transmits coded information to new cells.
The human eye has more than 137,000,000 light sensitive receptors, which translate everything you see instantaneously through your nervous system and your brain sees! Your eyes can communicate your emotions and are said to be the windows of your soul. Scientists estimate that the muscles in your eyes make more than 100,000 movements a day.
Your blood circulates through more than 60,000 miles of arteries, veins, and capillaries (enough to go around the world almost 3 times), and completes the cycle 1,000 times a day. The human heart beats more than 2.5 billion times in an average lifetime.
There are about 10,000 taste buds on the surface of your tongue and on the roof of your mouth that make eating so enjoyable. The digestive system then breaks down the food into smaller molecules, extracts the nutrients which are then absorbed into the blood. The blood delivers the nutrients to the cells throughout the body and gives us energy.
The human brain is made up of 12 trillion cells. Each cell connects to 10,000 other cells, making 120 trillion connections − more than all the telephone systems in the world combined. The brain sends and receives information to and from the cells through the nervous system instantaneously.
God is Great!
