| Respiration | exchange of oxygen and carbon dioxide (inhalation and exhalation) |
| inhalation (inspiration) | air is drawn in and the diaphragm contracts |
| 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 |

| 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 |
| Pleura | membrane that covers the lungs and lines the chest cavity |

| Lung cancer | is the leading cause of cancer death in both men and women |
| Chronic Obstructive Pulmonary Disease (COPD) | is a term used to describe any chronic lung disease that results in obstruction of the airways and limitation of air flow. |
| Upper Respiratory Infection | a common cold, |
| Emphysema | deteriorate and lose their elasticity in lungs |
| tracheostenosis | abnormal condition of a narrow/constricted trachea |
| spirometer | measure of breathing |
| pneumonocentesis | surgical puncture to remove fluid in the lung. |
| tracheitis | inflammation of the trachea |
