The nose is one of many parts of the human respiratory system. Air enters the body through the nose; the air is then then warmed and moistened. Air is also filtered from debris as it passes through the upper airway. Because it is the most prominent fixture on the human face, the nose has an effect on your appearance.

Many people experience issues with their noses. These can be as small as a stuffy nose, a minor nosebleed, or as extensive as serious breathing issues. Different solutions are available to help with these issues. However, before choosing one, it’s important to know the parts of the nose.

The Anatomy of the Human Nose

Looking at your nose, it might seem as if it is made up of only a few parts. However, there is far more to this structure of the body than it initially appears. The following are all parts of the human nose:

• Bone – The upper 1/3 to ½ of your nose is a hard bridge that is made up of two bones, one on each side and fused in the midline.
• Outer walls – The lower ½ to 2/3 of the nose are composed of lateral walls. These parts of the nose are made up of cartilage and covered in skin in the outside, and mucous membranes on the inside. These walls are the beginning of the nasal cavities, the nostrils, and the nasal tip.
• Nostrils – Also known as nares, these are the openings that lead to your nasal cavities. The nostrils are visible on the face.
• Nasal cavities – Two nasal cavities are found in the nose. These are the hollow areas on both sides of the nose where the air comes in and out. Each nasal cavity is lined with mucous membranes. They are divided by the septum.
• Cilia and hair – Cilia (small structures similar to microscopic hair) and hair are located inside the nose. These are used to trap particles like dirt. These items are then moved toward the nostrils so they can be wiped away or sneezed out, or the back of the throat so they can be cleared.
• Nerve cells – The cells in the nose are used to communicate with the brain. The nerve cells are what provide you with a sense of smell.
• Septum – The septum is made of both firm cartilage and bone. It goes down the center of the nose. A septum is used to separate the two nasal cavities and allow breathing through each nostril.
• Sinuses – Four pairs of sinuses are found in humans. These are little pockets filled with air that connect to the nasal cavities. The main purpose of the sinuses is to create mucus that keeps the nose moist inside.
• Turbinates – Also called conchae, three pairs of turbinates are found on the sides of each nasal cavity. These are folds that ensure the nose stays warm, while filtering debris as well. They also help moisten the air when you breathe it in and help with nasal drainage. These can swell tremendously with allergies.

As part of the respiratory system, the nose has many jobs. If you are experiencing issues with it, it is important to speak to a physician. There are many solutions to problems, whether related to the structure or aesthetics of the nose.

Not smoking, drinking lots of water, and keeping your living space clean can prevent many nasal issues. Using saline on a regular basis within the nostrils can also be useful for many people.
