We get rid of waste when we breath out and when we breath in we take oxygen in to our lungs and breath.
Your breath. Take a dump.
Matter has weight and takes up space. You know that air takes up space, because when you breath in, your lungs fill with air and expand. :) MoMMy.!
A breath of air goes through the nose and nasal passages, paranasal sinuses, and throat or pharynx. Next it goes down the voice box or larynx, trachea, bronchi, and bronchioles. Lastly to the lungs, the tiny respiratory bronchioles, alveolar ducts, alveolar sacs, and alveoli.

Not being able to take a deep breath is not always considered shortness of breath. If you are exerting yourself, where you need more air but can't take a deep breath, you would have a shortness of breath.
The average human normally takes in about 35 lbs of air per day.
Using the ruler on Google.earth I got 1688 air miles from the center of Riga, Latvia to the center of Madrid, Spain. The ruler takes the straightest path on a circle (the globe) and I am assuming that is the path the airlines would take.
