The Respiratory System
Just like us, horses (Suwatâga) need to breathe oxygen in order to fuel their muscles (ka). The respiratory system includes the lungs (Charhu) and the path that air takes to get to the lungs. Horse lungs (Charhu) are massive! Human lungs can hold 1.5x more air than an empty milk jug, but a horse’s lungs can hold 14 milk jugs worth of air!
Horses are obligate nasal breathers – they can’t breathe through their mouths. This is because the pathway between the mouth and the lungs is blocked off so that food doesn’t accidentally get brought into the lungs.
