Here is a list of structures to become familiar with: 1  Mouth and Nose- these are the openings where respiratory gases enter and leave the body. 2  Trachea (windpipe)- this passage way connects the mouth and nose to the lungs. 3  Lungs- these are the balloon-like structures that temporarily hold air in the body. Bronchial tube- the trachea breaks up into these smaller tubes to enter the right and left lungs. Bronchioles- within the lungs the bronchi split into these even smaller tubes which attach to the alveoli. Alveoli- these are the small sac-like structures where gas exchange occurs with the blood.
