Answer
Best,
Sinus cavities also occur in other mammals (among others). Several functions are considered:
– reduce the relative weight of the skull bones in the face
– insulation of tooth roots and eyes against rapid temperature fluctuations
– moistening and warming the inhaled air before it goes to the lungs
The sinuses run in such a way that the evacuation of mucus is made difficult when walking upright.
Possibly sinusitis is therefore typical for humans, and is less common in four-legged friends.
