The nasal cavity and its mucosa have two primary purposes in the process of breathing: Role as a Passage for Inhaled Air: During inhalation, air enters through the nostrils and passes via the nasal cavity into the pharynx and larynx, the next sections in the respiratory tract, to eventually reach the lungs.

How does the nasal passage work?

When filled with air they vibrate, thereby aiding speech. Through small openings, four pair of sinuses connect to your nasal cavity. With healthy sinuses, the air circulates freely through the chambers and mucus drains into the nose. Small hairs, called cilia, help move the thin, watery mucus through your sinuses.

What is the function of bronchi?

The bronchi, singularly known as a bronchus, are extensions of the windpipe that shuttle air to and from the lungs. Think of them as highways for gas exchange, with oxygen going to the lungs and carbon dioxide leaving the lungs through them. They are part of the conducting zone of the respiratory system.

What are bronchi?

Bronchi are the main passageway into the lungs. The bronchi become smaller the closer they get to the lung tissue and are then considered bronchioles. These passageways then evolve into tiny air sacs called alveoli, which is the site of oxygen and carbon dioxide exchange in the respiratory system.

Why is respiratory system important?

These include the nose, pharynx, larynx, trachea, bronchi and lungs. The respiratory system does two very important things: it brings oxygen into our bodies, which we need for our cells to live and function properly; and it helps us get rid of carbon dioxide, which is a waste product of cellular function.

Why do we have two nostrils?

Not to spoil the video, but the short answer is two nostrils provide a better sense of smell than just one. Studies have found that one nostril will generally operate better than the other on any given day. Thus, two nostrils provide a better ability to detect scents than one.

Are there nerves in your nose?

The two openings in the nose care called nostrils, or napes. They lead to two nasal cavities that are separated by the septum, a wall of cartilage. This part of the nose has many nerve endings that carry smell sensations to the brain, according to the American Rhinologic Society.
