Today's Interesting Fact

Ants don't have lungs. Ants don't have lungs like humans do. Instead, they take in air through very small holes on their body surface called spiracles. Spiracles are located on both sides of an ant's body. Air enters the body through the spiracles into a **tracheal system**. Since the tracheal system delivers oxygen directly to the body's tissues, blood doesn't need to transport oxygen like it does in humans. This method of respiration is possible because ants are small. In other words, ants have a unique respiratory system that can supply oxygen to their entire body without lungs.
