|
What is the Respiratory systems main functions |
Respiratory system mediates the uptake of oxygen for metabolism and the release of carbon dioxide into the atmosphere |
|
Ventilation |
Process of aerating the lungs |
|
How does the respiratory system work |
Air enters the nasal openings or the mouth into the trachea, which carries it through a system of branching tubes called bronchi and bronchioles to two lungs located on either side of the heart. |
|
Where does gas exchange in the lungs occur |
Occurs by diffusion , which is a passive transport mechanism |

The lungs is where Oxygen is added and carbon dioxide is removed to return ........ blood to the heart for circulation to the rest of the body |
Oxygenated |
|
Oxygen in the lungs moves into the ..... |
Blood |
|
Carbon dioxide in the blood moves into the ...... |
Lungs The lungs then exhale the co2 back into the atmosphere |
|
What is the amount of air breathes in and out of the lungs called ? |
Tidal volume |
|
The breathing control centers of the medulla oblongata of the brainstem control respiration through ...... |
Monitoring carbon dioxide levels and blood PH |
|
Alveoli |
Tiny air sacs in the lungs where exchange of oxygen and carbon dioxide takes place |
|
Bronchi |
The main passageways directly attached to the lungs |
|
Bronchioles |
Small passages in the lungs that connect the bronchi to the alveoli |
|
Perfusion |
The passage of fluid to an organ or tissue |
