Lesson #58: Horses and Vomit

Lawyer Housemate’s girlfriend is an equine vet, which is pretty cool all by itself. When she’s over and I hear about her day (today, she was shaving bits of flesh off an infected area of a horses’ leg that, according to her, resembled shaving kebab meat), I always end up learning something. Today?

I learned that horses cannot vomit.

This is because there’s a band of muscles around the esophagus that act as a one-way valve for things entering the stomach. A brief, but more in depth description of the physiology of this can be found here.
