Here’s your farm fact for today! Aren’t cows amazing?
While a lot of useful products come from cattle, by far the most amazing in my opinion is that their pulmonary surfactant is used to save premature infants lives.
How does that work?
When a baby is born early, they are not fully developed, and the lungs are really not ready for life outside the womb. One major issue is that their lungs do not have an adequate amount of pulmonary surfactant, the thing responsible for keeping the alveoli in proper working order.
The alveoli, which are all the tiny airsacs in the lungs responsible for the exchange of gases (oxygen and carbon dioxide), need surfactant to keep them from collapsing. When the alveoli collapse, they can also collect in the airway, making it especially hard for the baby to breath. Eventually, once enough alveoli collapse, the baby will not be able to breath anymore.
So where do cattle come in?
Pulmonary surfactant can be harvested from cows within minutes of them being butchered. This surfactant is processed and made ready to ship to hospitals worldwide. The bovine surfactant is then given to premature babies that need it to help them breath, saving their lives!
Just to be clear, the cows are not butchered just to get surfactant. They are being processed for meat as well as a lot of other products - they use everything but the moo - nothing is wasted. The surfactant is just an amazing added bonus.
Happy !
