No.
The driving force is differential pressures.
lungs
No, the [urinary] bladder does. The lungs are involved in the delivery of oxygen to the body and the excretion of carbon dioxide.
carbon dioxide
Both the internal as the external anal sphincter.
carbon dioxide
Excretion is the process of removing metabolic wastes. In the lungs, oxygen diffuses in to the capillaries, and carbon dioxide, a byproduct of cellular respiration, diffuses out. This makes CO2 the lung excretion.
In lungs alveoli is present where exchange of gases takes place, when blood with carbon dioxide is reached lungs then these alveoli purify by removing carbon dioxide
The respiratory system does "take away" carbon dioxide by replacing it with oxygen, through breathing. Exhaling causes the body to expel carbon dioxide and inhale oxygen.
The carbon dioxide is exhaled.
Carbon dioxide is excreted from the lungs.
No. Your lungs pass oxygen into the blood and also pass carbon dioxide to the air outside your body. Oxygen combines with carbon to form carbon dioxide. This happens in our muscles, among other places.
