the respiratory system
The respiratory system supplies the body with oxygen and expels carbon dioxide.
Breathing involves getting oxygen into your system and it expels carbon dioxide, which is a waste.
The respiratory system provides the mechanism for the body to obtain oxygen and excrete carbon dioxide.
The respiratory system
Paramecium does not have a respiratory system like humans do. It absorbs oxygen directly from its environment through its cell membrane, and expels carbon dioxide in a similar manner.
The gases that are exchanged are oxygen and carbon dioxide.
The circulatory system takes up oxygen, and releases carbon dioxide.
The respiratory system moves oxygen in and carbon dioxide (CO2) out.
The respiratory system utilises oxygen from the environmrntal gases and expires carbon dioxide (CO2).

The Respiratory system carries oxygen and carbon dioxide
The respiratory system takes in oxygen through the lungs and eliminates carbon dioxide through exhalation. Oxygen is exchanged with carbon dioxide in the alveoli of the lungs during the process of respiration.
