Nose is the primary organ of smell and functions as an important respiratory organ in the body. Along with its effect on physical appearance, the nose also plays a significant role in several other bodily functions, including respiration and the human sense of smell and taste. The external part of the nose has a triangular or pyramidal shape, with the highest point of it referred to as the apex or the tip of the nose [3]. The human nose, according to wikipedia is the most protruding part of the face. Anything that human nose cannot smell is lethal to humans.
