trachea (windpipe)
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.
nostril->nasopharynx-> oropharynx->glottis-> trachea-> left and right bronchi-> bronchioles->alveoli (where gas exchange occurs)
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.
yes,technicly it is because you take air into your lungs.

Yes, when you inspire you take in a breath; when you expire you breathe out.
Air will enter the nostrils or oral cavity, pass through the nasopharynx, pass through the oral pharynx and through the glottis into the trachea, enter either the right or left bronchi, travel into the bronchioles, and be absorbed to the blood stream at the alveoli. Carbon dioxide will reverse this path to the point of exhalation.
