Answer 1

The external nose is primarily responsible for the sense of smell.

Step-by-step explanation:

The structure that most people would call the nose, specifically the external nose, is primarily responsible for the sense of smell. The external nose consists of various surface and skeletal structures, including the nostrils and the alae, which contribute to the sense of smell. Olfactory receptors, located in the olfactory epithelium within the nasal passages, detect chemicals in the air and send signals to the olfactory bulb of the brain, thus allowing us to smell different odours.
