How does a giraffe vomit?

Answer 1

Great question!

with such a high neck the forces of gravity seem to work against the poor animal!

Fortunately the muscles of the esophagus are very strong-

The esophagus is a long muscular tube connecting your mouth and your stomach.

There are muscles at the top and bottom of the esophagus that control things coming and going, much like control valves-this is called peristalsis. These muscles are called the upper and lower esophageal sphincters. when we eat food-the stomach functions as a reservoir for holding the food-which it does with 2 very large muscles.

When a person or animal throws up, the lower-esophageal sphincter opens so that as the stomach squeezes, there is nothing to keep the food in the stomach and so it comes back up the esophagus.

Answer 2

Giraffes have a unique physiology that makes it extremely difficult for them to vomit. Their long necks and powerful muscles in the lower esophagus prevent them from regurgitating food in the way that other animals can. If a giraffe were to try to vomit, it could potentially be very harmful to their delicate throat and airway.
