The Respiratory System

The system of the body we are most acutely aware of is the respiratory system. We have to breathe, whether voluntarily or involuntarily, every few seconds in order to stay alive. Because we looked at the circulatory system, we know that this is because we have to get oxygen to every nook and cranny of the body. But how does oxygen enter the bloodstream in the first place? Let's take a closer look!

hey Dave, you forgot about the internal nares near the nasopharynx its explanation is:
Air enters the nasal cavity from the outside through two openings: the nostrils or external nares. The openings from the nasal cavity into the pharynx are the internal nares. Nose hairs at the entrance to the nose trap large inhaled particles.
