You spontaneously grow gills and then that works.
Expel
Plants take in Carbon Dioxide and expel Oxygen as a by-product of cellular respiration. Animals take in Oxygen and expel Carbon Dioxide as a by-product of cellular respiration.
They take in oxygen, and expel Carbon dioxide as a waste product.
Carbon Dioxide
It's taken into the lungs, where the alveoli absorb oxygen and expel carbon dioxide. When you breathe out, the carbon dioxide dissipates into the atmophere.
Carbon dioxide is the result of the reaction between the yeast compounds and the gluten. The heat process causes the compounds to expel the carbon dioxide, which expands more than the oxygen in the bread.
The roots take in water and food - the leaves expel carbon dioxide.
Spiracles are the mechanism through which butterflies take in oxygen and expel carbon dioxide
the answer is a vein
Plants expel oxygen as a byproduct of photosynthesis. This process takes carbon dioxide and breaks it into carbon and oxygen.
You do not expel any gas when inhaling. Inhaling is the act of taking air in, if you mean when exhaling (breathing out) then carbon dioxide (aka CO2)
Just like you the expel a lot of carbon dioxide due to respiration.
