- motion Ex. snails
- homes Ex. cave swiftlet

LaoNasal passages are used for breathing air into and out of the lungs. They help filter, warm, and moisten the air before it reaches the lungs. Additionally, nasal passages contain sensory receptors that assist in detecting smell.
- The nasal cavities are lined with ciliated connective tissue and a mucous membrane which filters dust and moistens inhaled air.
- The air is warmed by the blood capillaries in the turbinate bones.
- There are olfatory receptors, nerves, inside the nasal passages which register smell via the brain.
They are the passages allowing in air to our lungs. They allow incoming air to pass over our smell receptors and filter out insects with hairs and warm the incoming air.
