What is little area give its importance?

As this air enters, it is important that its temperature is adjusted for optimum gas transfer in the lungs. This adjustment is achieved via heat exchange between the air and the blood being supplied to the nasal cavity. Little’s area is a common site of epistaxis (nose bleeds) in both paediatric and adult cases.
