Imagine you are a following the path of an oxygen molecule into the body. List the following structures in the correct order that the oxygen molecule would travel through them. Start with where oxygen would enter the body and end the location at which oxygen would enter the blood. TRACHEA, LARYNX, ALVEOLUS, BRONCHIOLE, PULMONARY CAPILLARY, NASAL CAVITY, PHARYNX, and BRONCHUS.

nasal cavity, pharnyx,larynx, trachea,bronchus, bronchiole,alveolus

Explanation:the respiratory system consists of structures that are responsible for taking in oxygen from the atmosphere to the blood stream and carbon dioxide out of the body. It contains structures such as the nasal cavity, pharnyx larynx,trachea,two bronchi,the lungs etc.

The respiratory system help to transfer oxygen and carbon dioxide.it also helps maintain water balance, temperature and acid/base balance.

The pharnyx carries air to the larynx.the trachea is an air passage in the throat maintained by rings of cartilages .the bronchi consist of bronchioles.they are small division of the bronchi.they allow contraction and relaxation thereby regulating air movement on to the alveoli.the aveoli are the tiny end of the aveolar ducts.they exchange oxygen and carbon dioxide with the blood.
