exhalation (expiration) air is pushed out from alveoli and diaphragm relaxes
cellular respiration use of oxygen and nutrients to produce energy, water, and carbon dioxide
nose a way that air enters the respiratory system that contains nares
mouth a way that air enters the respiratory system
cilia tiny hairs that filter out dust and other particles that enter the nose

Trachea windpipe, extends from larynx to bronchi
Bronchi branches of trachea leading to lungs
Carina The piece that divides trachea into the bronchi
Bronchioles small tubes (thin as a strand of hair) in lungs branching from bronchi to alveoli
Alveoli tiny air sacs, where gas exchange takes place.
Lungs pair of lobed organs in chest cavity,
Diaphragm muscle that contracts and causes air to enter the lungs
