Take the Body By Numbers Challenge! Name 10 Body Parts that only have three letters. It's tougher than you think. (See Answers Below.)
206 Bones, 100,000 Heartbeats a day, 120,000 Hair Follicles, 93,000 miles of Nerves, 300 Impulses,
10 Pints of Blood, 60% of Body is Water, 10,000 Smells. Know it or not, you've got fantastic stats.
Everybody knows that a child has 300 bones that fuse into 206 bones by adulthood.
(you knew that didn't you?) But did you know that some people have an extra bone in the arch of the foot, and that one in every 20 people has an extra rib? You do now!
Although your heart's only about the size of a fist and weighs only about a half to 3/4 of a pound, each day it does the amount of work it would take to lift the body one mile straight up, beating 100,000 times a day and 2.5 billion times in a lifetime.
You have 93,000 miles of peripheral nerves. (See why you're nervous?) Your fastest nerves send impulses at up to 395 feet/second at up to 300 impulses per second. (See why you're impulsive?)
You have more than 640 skeletal muscles. Which muscle is the largest. You're sitting on it.
Your body has about 10 pints of blood - about the same as the amount of oil in a V-8 engine.
(Vroom! Vroom!)
The average head is home to 120,000 hairs, with as many as 140,000 for natural blondes and as few
as 90,000 for natural redheads. (Your head may differ, please comb accordingly.)
Although we can recognize 10,000 different smells, there are only four basic types of smell - Fragrant,
Acid, Rancid and Burnt. (We know what you're thinking, don't go there.) Smell is the sense we get accustomed to most quickly; most odors can hardly be perceived just 30 seconds after they are first
detected. (We know what you're thinking, don't go there.)
You can hear sound frequencies from 20 Hz (Hertz or waves per second) to 20,000 Hz. You can hear some lower frequencies than a bat can, but you can also hear some higher frequencies than a bird can. Of course, bats can hear higher frequencies than us, and birds can hear lower frequencies than us. (Oh, and bats and birds beat us in the "being-able-to-fly" department as well.)
if you're wishy-washy, maybe it's because your body is 54% to 60% water (by weight), and only 18% bone.
(Slosh, slosh.)
