Nose is the primary organ of smell and functions as an important respiratory organ in the body. A nose is a protuberance in vertebrates that houses the nostrils, or nares, which receive and expel air for respiration alongside the mouth.behind the nose are the olfactory mucosa and the sinuses.behind the nasal cavity, air next passes through the pharynx, shared with the digestive system, and then into the rest of the respiratory system.in humans, the nose is located. It bears the nostrils and is the first organ of the respiratory system. We now have efficiently developed human nostril organoids from each adults and infants.” the cells lining the within of the nostril, the epithelium, are uncovered to air on one aspect.
