Horses' airways and lungs

May 23rd, 2022

A racehorse moves roughly 1,800 liters of air in and out of its lungs during a five-furlong (5/8 mile) race. That's equivalent to six bathtubs full of air! The harder a horse works, the more its respiratory system is called upon to move oxygen into and carbon dioxide from the lungs. Learn more about the intricate system of horses' airways, lungs, and respiration in this online resource by Dr. David Marlin available on The Horse.
