How does air travel through the respiratory system in order?
When you inhale through your nose or mouth, air travels down the pharynx (back of the throat), passes through your larynx (voice box) and into your trachea (windpipe). Your trachea is divided into 2 air passages called bronchial tubes. One bronchial tube leads to the left lung, the other to the right lung.
What is the order of the respiratory system?
The flow of air from the environment moves through the respiratory system in these sequential steps during inspiration: Nose or mouth > pharynx > larynx > trachea > the right or left bronchi of the lung > bronchioles of the lungs > alveoli of the lungs.
Where does the air enter the respiratory system?
Air enters through the nose (and sometimes the mouth), moves through the nasal cavity, the pharynx, the larynx, enters the trachea, moves through the bronchi and bronchioles till the alveoli. The pathway of air in the respiratory system starts with the external organs of the nose and mouth.
Why is the pharynx important to the respiratory system?
As it travels, the air makes rapid swirls of movement in order to cause small particles in the air to stick to mucus. It is also humidified, filtered, and warmed. The pharynx is a pathway in which both air and food travel, henceforth it is an important passage for the digestive and respiratory tracts.
Where does air go after passing through the trachea?
Trachea: Air now enters the windpipe which is situated behind the sternum (breastbone) and between the two lungs. Bronchus: From the trachea, two bronchi (one bronchus for each lung) enter the lungs and divide and subdivide into secondary and tertiary bronchi, getting narrower as they proceed into the lung. Bronchioles: The…
Which is the most flexible pathway in the respiratory system?
The Pathway of Air Through The Respiratory system. These bronchi are even more flexible than the primary. After air passes through the secondary bronchi, it then reaches the tertiary bronchi, which are even smaller pathways. Bronchioles: Bronchioles are the finest conducting pathways within the respiratory system.
