24 New Era Most sacred of all, our bodies have the power to procreate— to create life. When you receive information through one of your senses, the signal travels from your nerves to your brain at over 100 miles per hour (160 kph). When your brain is alerted to danger, adrenaline is released, which acceler- ates your heart rate, increases breath- ing, dilates the pupils, and shuts down your digestive system to allow other muscles to contract with incredible force. Your immune system, using glands like your adenoids and organs like your thymus and spleen, can protect you from harmful viruses and bacteria. e human heart beats more than three billion times in an average lifespan. at’s more than 100,000 times per day. Hearing is the fastest human sense. Your brain can recognize a sound 10 times faster than the blink of an eye, in as little as 0.05 seconds. Your brain produces enough electricity to light a small light bulb. For blind people, the brain’s visual cortex changes in order to respond more to touch and hearing. Two eyes give you binocular vision, which helps with depth perception. Test it by closing one eye and trying to touch a small item near you. e human eye can distinguish thousands of different col- ors, and your nose can recognize thousands of different scents. e most expensive digital camera today can capture 400 mega- pixels, but the human eye can see 576 megapixels. Blood distributes nourishment from your digestive system. Blood takes the body’s waste to the kidneys and liver to be sorted and trashed.
