5. What is the function of the conchae in the nasal cavity? 1. increase surface area 2. exchange gases 3. maintain surface tension 4. maintain air pressure

## Step 1<br />The conchae, also known as nasal conchae, are structures in the nasal cavity. They are shaped like seashells and are responsible for increasing the surface area of the nasal cavity.<br /><br />## Step 2<br />The increased surface area allows for more efficient warming and humidifying of the air we breathe in. This is because the increased surface area provides more space for the air to come into contact with the mucous membranes lining the nasal cavity.<br /><br />## Step 3<br />The other options, such as exchanging gases, maintaining surface tension, and maintaining air pressure, are not the primary functions of the conchae. These functions are typically associated with other structures in the respiratory system.
