How Will You Describe The Pathway Of Oxygen To The Breathing System

How will you describe the pathway of oxygen to the breathing system

Answer:

When we inhale oxygen gas using our nose or mouth, our diaphragm moves down and do contracting. And that is the reason why it drops in air pressure. From outside, the oxygen comes in fastly until it goes down the Trachea or the windwipe up to the Lungs. The Lungs will expand itself to fill more oxygen and bring in to its tubes or air sacs. And some of it will be mixed in blood stream to become or make oxygenated blood. it will travel up to the Capillaries and dump off Carbon Dioxide. At the end, we will make exhalation of Carbon Dioxide(CO2).
