Welcome to Fast Facts with Reasons for Hope!
I’m Carl Kerby, and we’re talking about the giraffe.
“What’s the problem with a giraffe getting a drink of water?” you ask.
Let me ask you a question first, “Does gravity work in Africa?” Not that gravity!
This gravity.
You’re saying, “What?”
Well, because of gravity, if you bend over for a couple of minutes, the blood would rush to your head, and you’d get a headache.
An adult bull giraffe can have a 2.5-foot-long heart with 3-inch thick muscle walls to pump blood 18 feet into the air.
When they bend over, they shouldn’t just get a headache, gravity should take over and make their head explode. But it doesn’t.
And the reason why is nothing short of a miracle. At the base of their brain, they have a tiny mass of blood vessels, called the “wonder net,” that catch the blood and diffuses it to the brain at just the right rate so that they don’t have a stroke and die.
They also have “one-way valves” in their arteries that keep blood that’s returning from their brain back to the heart from flowing back to their brain and killing them.
Take a look! Amazing!
There’s more … next time with Fast Facts with Reasons for Hope.
Until then … stay bold!
