Final answer:
A nasal cannula is a two-pronged device used to deliver oxygen directly into the nose. It's a light, easy-to-use alternative to a mask, allowing patients to move while receiving their treatment. The oxygen travels from the pharynx, to the trachea, bronchi, bronchioles, alveolar ducts, and finally to the alveolar sacs where it enters the bloodstream.
Step-by-step explanation:
Yes, a nasal cannula is indeed a two-pronged plastic device for delivering oxygen into the nose. This is used in various scenarios where an individual requires additional oxygen, such as certain respiratory diseases. The nasal cannula is a lightweight alternative to a mask and allows for mobility while receiving oxygen.
The oxygen supplied through a nasal cannula begins its journey in the nose and then follows the usual respiratory pathway. When we breath in, the oxygen travels from the pharynx to the trachea. It then moves into the bronchi which divide into smaller tubes called bronchioles. Finally, it arrives at the alveolar ducts which connect to alveolar sacs where oxygen is delivered to the blood.
