The air travels through the respiratory system during inhalation in the next order:
<em><u>Nasal cavity:</u></em> You inhale air into your nose.
<u><em>Larynx:</em></u> The air travels down to this organ, a hollow, tubular structure that plays a key role in phonation, respiration, and deglutition.
<u><em>Trachea:</em></u> (Or <em>windpipe</em>) is a wide, hollow and cartilaginous tube that connects the larynx to the bronchi.
<em><u>Bronchi:</u></em> The trachea divides into two primary bronchi; they are the main passageway into the lungs.
<em><u>Bronchioles: </u></em>The bronchi develop smaller the closer they get to the lung tissue and are then consider bronchioles.
<em><u>Alveoli:</u></em> They are tiny air sacs located at the end of the bronchioles, which is the site of oxygen and carbon dioxide exchange in the respiratory system.
Yes, Almost ALL cells have the same DNA in a human body. This is because our DNA is inside our Nucleus. DNA is the same in every cell in a human body. Hope this helps! ~
The first thing that the etiologist can do is try and culture bacteria from the tissue samples in the lab. And then study about the bacterium's properties and characterstics that are leading to causing diseases in the humans.
