What is the respiratory pathway?

Respiratory System: Pathway of air: nasal cavities (or oral cavity) > pharynx > trachea > primary bronchi (right & left) > secondary bronchi > tertiary bronchi > bronchioles > alveoli (site of gas exchange)

Which of the following is a correct path of air through the respiratory tract quizlet?

The path of air through the respiratory tract is: trachea, bronchi, bronchioles, alveoli. It is important to note that no gas exchange takes place in the bronchi, but does in the bronchioles, which are passageways that branch off from the main bronchi and eventually lead to alveolar ducts.

How does hair in the nasal cavity protect the respiratory system?

Tiny hairs called cilia protect the nasal passageways and other parts of the respiratory tract, filtering out dust and other particles that enter the nose through the breathed air. These two openings of the airway (the nasal cavity and the mouth) meet at the pharynx, or throat, at the back of the nose and mouth.

Where does the air enter the body to take one breath?

The process of which a person takes one breath is called the respiratory cycle. The Nose: First, air enters your body either through your nose or your mouth, where it is then held in your nasal cavity/oral cavity.

Which is the pathway of air to the lungs?

Pathway of the air to the lungs: Pharynx–> Larynx–> Trachea–> Bronchus–> Bronchiole–> Aveolus–> Lung. The respiratory system is made up of the organs involved in the interchanges of gases, and consists of the: Nose. Mouth (oral cavity) Pharynx (throat) Larynx (voice box) Trachea (windpipe)

Where does the respiratory system start and end?

The respiratory system starts at the nose and mouth and continues through the airways and the lungs. Air enters the respiratory system through the nose and mouth and passes down the throat (pharynx) and through the voice box, or larynx.

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…

What are the correct pathways of air in respiratory system?

Furthermore, what is the correct order of air flow from the nose to the alveoli in the lungs? The respiratory route air passes through is: Nostrils → nasal cavity →Pharynx → Larynx →Trachea → Bronchi (with cartilaginous rings) →Bronchioles (without rings) → Alveoli (air sacs).

Where does the air go when you breathe in?

Where the Air Goes As you breathe air in through your nose or mouth, it goes past the epiglottis and into the trachea. It continues down the trachea through your vocal cords in the larynx until it reaches the bronchi. From the bronchi, air passes into each lung.
