What is the primary organ of the respiratory system?
The lungs
What is the function of the lungs?
To carry out the gas exchange that occurs as we breathe.
How do the lungs work?
Red blood cells collect the oxygen from the lungs and carry it to the parts of the
body where it is needed. The red blood cells then collect the carbon dioxide and
transport it back to the lungs, where it leaves the body when we exhale.

Anoxia
Complete lack of oxygen

Sinuses

Pharynx
connects the nasal and oral cavities with the larynx and esophagus. It is commonly
referred to as the throat. In the digestive system, its muscular walls function in the
process of swallowing and it serves as a pathway for the movement of food from
the mouth to the esophagus. As part of the respiratory system, it allows for the
movement of air from the nose and mouth to the larynx in the process of
breathing.
Nasopharynx
The part of the pharynx that lies above the soft palate; anteriorly it opens into the
nasal cavities through the choanae; inferiorly, it communicates with the
oropharynx through the pharyngeal isthmus; laterally it communicates with
tympanic cavities through pharyngotympanic (auditory) tubes.
