Step 1-
Your diaphragm moves down as it contracts. Your ribs move outward. These movements make the space inside the chest larger.
Step 2-
Air rushes in through the nose and mouth and passes through the throat. Air then moves past the epiglottis which is open into the trachea.
Step 3
Air moves into your bronchi. The bronchi branch out and end in tiny air sacs, called alveoli.
Step 4
<span>Air moves into your alveoli. Oxygen moves through the walls of alveoli and capillaries, entering the blood.</span>
Step 5
Carbon dioxide moves from the blood through the walls of capillaries and alveoli in order to be expelled by the lungs.
Step 6
Your diaphragm moves up as it relaxes. Your ribs move inward. These movements make the space inside the chest smaller.
Step 7
<span>Your lungs are squeezed and air is pushed out of the alveoli. The air travels back through your bronchi, trachea, and nose and mouth.</span>

Answer:
Different parts and regions have distinct features and characteristics.
Colorado is known to have lots of mountains. Florida is however a humid-subtropical region. This makes differences in the types of loving organisms found in the named region. There are also different ages in geological structures.
Colorado has lots of rocks in the region and is as result of the presence of rigid hills and mountains while Florida is more tropical and has a coastal processing climate with low prevalence of rocks.
It allows them to be flattened on a microscopic slide, so that the chromosomes of individual cells can be observed easily.
