What is Nose?
The nose is an important part of the human body. It is the organ responsible for our sense of smell and it helps us to breathe. The nose also plays an important role in how we look, as it can be a major part of facial features.The nose is made up of several parts, including two nostrils, the septum, and bony ridges that divide the nostrils into three distinct areas the left, right and middle parts. Inside each nostril are hair-like cilia which help filter incoming air for foreign particles. The septum separates the two sides of the nose and allows air to flow freely through both nostrils.Noses vary greatly from person to person in terms of shape and size; some noses are long and thin while others are short and wide. Noses also come in different colors depending on one’s skin tone they can range from pale pink to dark brown or even black. Additionally, some people have more prominent noses than others due to genetics or environmental factors like excessive sun exposure or tanning beds. Noses serve many functions beyond our sense of smell; they help us detect changes in temperature (such as when we experience a cold breeze) as well as protection against foreign particles like dust, pollen or smoke that could irritate our respiratory system if inhaled directly into our lungs. Furthermore, noses play an important role in communication; they express emotions such as joy or sadness through facial expressions by wrinkling or flaring up when needed. In conclusion, noses play an integral role in both how we look aesthetically and how we interact with our environment on a daily basis from helping us breathe easier during physical activities to allowing us to better express ourselves emotionally through facial expressions.
