|
|
organs of the respiratory system |
grouped into upper respiratory and lower respiratory tracts |
|
|
upper respiratory tract |
nasal cavity, pharynx and larynx |
|
|
lower respiratory tract |
trachea and bronchial tree of lungs |
|
|
the conducting portion |
conducts air between the external environment and the gas exchange surfaces within the lungs. consists of: the nasal cavity, pharnyx, larynx, trachea, bronchi, and terminal bronchioles |
|
|
the respiratory portion |
the site of Gas exchange between the lungs and the blood stream. consists of: respiratory bronchioles and the alveoli. |

Ventilation |
Process of moving air in and out of the lungs. 1. Inhalation (inspiration): brings fresh air into the alveoli of the lungs where oxygen is loaded onto the red blood cells for delivery to the cells of the body. 2. Exhalation (expiration): expels stale air containing carbon dioxide that was removed from the blood stream. |
|
|
Respirator event represented by downward pull of the rubber sheet of the bell jar lung. |
Diaphragm is contracting down wards, giving more space for lungs to expand. As well as the external innercostals contracting to lift rib cage upwards allowing more room. (Pressure decreases outside lung and volume increase) the pleura cavity attaches both visceral and parietal sides. Where one moves so does the other. |
|
|
Tidal volume (TV) |
Volume of air moving into or out of the lungs during queit breathing Male and female= 500 mL |
|
|
Inspiratory reserve volume (IRV) |
Maximum volume of air that can be inhaled above Tidal volume. |
|
|
Expiratory reserve volume (ERV) |
Maximum volume of air that can be exhaled below Tidal volume |
|
|
Residual volume (RV) |
Volume of air that remains in respiratory system after a maximal exhalation |
|
