helps move oxygeon into the body
Through nose.
Air moves in and out of the external nares, also known as the nostrils. During inhalation, air enters the respiratory system through the external nares, where it is filtered, humidified, and warmed before reaching the lungs. During exhalation, air exits the respiratory system through the same external nares.
Human nostrils serve as the primary entry points for air into the respiratory system. When we inhale, air flows through the nostrils, where it is filtered by tiny hairs (cilia) and mucus that trap dust, allergens, and pathogens. The air is then warmed and humidified before passing into the nasal cavity, which contains olfactory receptors that detect odor molecules, allowing us to smell. Additionally, the nostrils can vary in size and shape, which can influence airflow and the efficiency of breathing.
Aerodynamic.
Yes, air flows through the nasal septum, which is the thin wall of cartilage that divides the nostrils. The nasal septum helps regulate the airflow and directs it to the lungs.
Nostrils are one of the ways that air is taken into the lungs, it is just through the nose rather than the mouth. Hairs in your nostrils filter dirt from the air. Air taken in through the nostrils also passes by smell receptors (olfactory receptors), which allows you to get chemical information about your environment.
Its function is to take dust out of the air as it passes through your nostrils to the lungs. That's why it is sticky.
They breathe air - through their nostrils which lead down to their lungs !

It breathes through its nostrils !
Air moves through the nostrils or mouth, then passes through the pharynx, larynx, trachea, bronchi, bronchioles, and finally into the alveoli of the lungs where oxygen is exchanged with carbon dioxide.
Breathing. Inhaling oxygenated air through our nostrils.
They breathe - by inhaling air through their nostrils !
Through nose.
Air is sucked into the lungs through the nostrils of the nose or mouth.
During the first inspiration, the air travels through the nostrils, also called nares, of a bird, which are located at the junction between the top of the upper beak and the head. The fleshy tissue that surrounds them, in some birds, is called the cere. As in mammals, air moves through the nostrils into the nasal cavity. From there it passes through the larynx and into the trachea. Air moves through the trachea to the syrinx, which is located at the point just before the trachea divides in two. It passes through the syrinx and then the air stream is divided in two as the trachea divides. The air does not go directly to the lung, but instead travels to the caudal (posterior) air sacs. A small amount of air will pass through the caudal air sacs to the lung. During the first expiration, the air is moved from the posterior air sacs through the ventrobronchi and dorsobronchi into the lungs. The bronchi continue to divide into smaller diameter air capillaries. Two kinds of capillaries flow side by side, in opposite directions - the air flowing caudal to cranial and the blood flowing cranial to caudal (in general). This acts as a "countercurrent exchange" mechanism. Blood capillaries flow through the air capillaries and this is where the oxygen and carbon dioxide are exchanged. When the bird inspires the second time, the air moves to the cranial air sacs. On the second expiration, the air moves out of the cranial air sacs, through the syrinx into the trachea, through the larynx, and finally through the nasal cavity and out of the nostrils.
They breath through their nostrils - situated on the top of their skull.
