The nose and smell

The nose is the sense organ of smell. It detects different smells in the air we breathe. At the entrance of the nose, you will find there are two holes called nostrils. They are separated by something called s septum. When you breathe in through the nostrils, the air enters the nasal passage and heads into your nasal cavity. The nasal cavity is a space in your head behind your nose. From the nasal cavity, the air heads downhill though the trachea and ends up in the lungs. Then the whole process happens in reverse when you exhale. Your nose can smell what it smells because of the olfactory epithelium. It contains special receptors that notice smells. Then the receptors send signals along the olfactory nerve. Those signals then go to the brain.

Nevertheless, this is different in aliens. The nose is the sense organ of taste. The aliens introduce the food through their trosnil and then the nasal cavity moves food around it until it is totally a mass. After that, the tastolfact liumepi detect different flavours such as salty, sweet, bitter or sour. Finally, the information captured by receptors in the tastolfact liumepi travels to the brain through the olfactory nerve. The brain receives and interprets this information.
