GENERAL KNOWLEDGE

Detailed explanation-1: -The nose has two holes called nostrils. The nostrils and the nasal passages are separated by a wall called the septum (say: SEP-tum). Deep inside your nose, close to your skull, your septum is made of very thin pieces of bone.

Detailed explanation-2: -Our nostrils have evolved to perform both roles, although each nostril prefers one role over the other at different times. At any given moment, one nostril may draw in more air than the other, whereas the other nostril will draw in less air, which allows it to better pick up certain scents in the environment.

Detailed explanation-3: -The external openings are known as nares or nostrils.

Detailed explanation-4: -When two people greet each other by rubbing their noses together, we call this cute gesture an Eskimo kiss. The commonly told story of Eskimo kisses is that people living in the frigid north can’t engage in a traditional mouth-to-mouth kiss because their lips might freeze together in the cold.
