|---|---|
| Alveoli | Microscopic air sacs in the lungs. |
| Bronchi | Two main branches of the trachea; air tubes to and from the lungs. |
| Bronchioles | Small branches of the bronchi; carry air in the lungs. |
| Cellular Respiration | Respiration on a cellular level. |
| Cilia | Hairlike projections. |
| Epiglottis | Leaf-shaped structure that closes over the larynx during swallowing. |
| Expiration | The expulsion of air from the lungs; breathing out air. |
| External Respiration | The exchange of oxygen and carbon dioxide between the lungs and bloodstream. |
| Inspiration | Breathing in; taking air into the lungs. |
| Internal Respiration | The exchange of carbon dioxide and oxygen between the tissue cells and the bloodstream. |
| Larynx | Voice box, located between the pharynx and trachea. |
| Lungs | Organs of respiration located in the thoracic cavity. |
| Nasal Cavity | Space between the cranium and the roof of the mouth. |
| Nasal Septum | Bony and cartilaginous partition that separates the nasal cavity into two sections. |
| Nose | The projections in the center of the face; the organ for smelling and breathing. |
| Pharynx | The throat. |
| Pleura | A serous membrane that covers the lungs and lines the thoracic cavity. |
| Respiration | The process of taking in oxygen (inspiration) and expelling carbon dioxide (expiration) by way of the lungs and air passages. |
| Respiratiory System | Consists of the lungs and air passages; responsible for taking in oxygen and removing carbon dioxide. |
| Sinuses | Cavities or air spaces in bones. |
| Trachea | Windpipe; air tube from the larynx to the bronchi. |
| Ventilation | Process of breathing. |
| Asthma | Respiratory disorder caused by a sensitivity to an allerge, stress, overexertion, and/or infection. |
| Bronchitis | Inflammation of the bronchi and bronchial tubes. |
| Chronic Obstructive Pulmonary Disease | Any chronic lung disease that results in the obstruction of airways. |
| Emphysema | A nonenfectious, chronic respiratory condition that occurs when the walls of the alveoli deteriorate and lose their elasticity. Carbon dioxide becomes trapped in the lungs. |
| Epistaxis | Nosebleed which occurs when capillaries in the nose become cngested and bleed. |
| Influenza | Highly contagious viral infection of the upper respiratory system. |
| Laryngitis | Inflammation of the larynx and vocal cords. |
| Lung Cancer | Leading cause of cancer death in men and women; tumor or tumors in the lungs. |
| Pleurisy | Inflammation of the pleura, or membranes, of the lungs. |
| Pneumonia | Inflammation or infection of the lungs characterized by exudate, a build up of fluid in the alveoli. |
| Rhinitis | Inflammation of the nasal mucous membrane, relulting in a runny nose, watery eyes, sneezing, soreness, and congestion. |
| Sinusitis | Inflammation of the mucous membrane lining the sinuses. |
| Sleep Apnea | Conition in which an individual stops breathing while asleep. |
| Tuberculosis | Infectious lung disease caused by the bacterium Mycobacterium tuberculosis |
| Upper Respiratory Infection | Common cold, inflamation of the mucous membrane lining the upper respiratory tract. |
