Term | Definition |
Alveoli | Tiny air sacs in the lung at which gas exchange takes place. (blood flow exchanges oxygen & carbon dioxide) |
Bronchial tree | Series of ever-decreasing-size tubes branching form the bronchi and ending with bronchioles in the lungs |
Chronic obstructive pulmonary disorder (COPD) | Disorders that cause a long-term decrease in ventilation of the lungs |
Compliance | Measurement of how well the lungs can expand and return to shape |
Expiration | Movement of air out of the lungs |
Functional residual capacity (FRC) | The amount of air remaining in the lungs after the expiration of a normal breath at rest |
Gas exchange | The movement of oxygen and carbon dioxide that occurs between capillary blood and the alveoli in the lungs and between capillary blood and the tissues of the body |
Gas transport | The movement of gases in the blood to and from the lungs and tissues |
Inspiration | Movement of air into the lungs |
Inspiratory reserve volume (IRV) | The amount of air that can be forcefully inspired beyond the amount inspired in a normal breath at rest |
Partial pressure | The amount of pressure an individual gas contributes to the total pressure of a mixture of gases |
Pharynx | Throat. An area that is divided into 3 sections based on location and anatomy (the nasopharynx, the oropharynx, the laryngopharynx) |
Pneumothorax | **No per instructor** A condition in which air is introduced in the pleural cavity between the pleural membranes; commonly called a collapsed lung |
Respiratory membrane | **No per instructor** A membrane that is composed of a thin layer of water with surfactant in the alveoli, a single squamous cell alveolar wall, and a single cell capillary wall and across which gas exchange takes place in the lung |
Spirometry | Measurement of lung volumes and capacities |
Surfactant | Fluid secreted by great alveolar cells in the lungs that reduces the surface tension of water |
Tidal volume (TV) | The amount of air moved in a normal breath (inspired or expired) at rest |
Ventilation | Airflow to the lungs |
Ventilation-perfusion coupling | The matching of airflow to blood flow in the lungs |
Vital capacity (VC) | The maximum amount of air that can be moved |
