Uniquely Designed Lungs
Manage episode 509505712 series 90015
This week we’re looking at the intricacies of bird flight. In addition to complex feathers and hollow bones, birds also need a special respiratory system—or flight couldn’t happen.
Their high-energy muscles, like wings, need plenty of oxygen, and regular lungs wouldn’t work. Instead, special branching air sacs bring oxygen straight to the heart, lungs, and stomach.
Birds don’t breathe in and out like we do. They can inhale oxygen without expelling carbon dioxide first. So they always have a continuous supply of fresh air!
There’s no way all the parts needed for flight evolved. Flight shows the Creator’s fingerprint.
