Expel
Yes, breathing is primarily regulated by the levels of carbon dioxide in the blood. When carbon dioxide levels rise, the body signals the need to breathe more to expel excess carbon dioxide and take in fresh oxygen. Conversely, if carbon dioxide levels drop too low, breathing may decrease to retain carbon dioxide.
Actually, when people hyperventilate, they loose carbon dioxide. The old way of treating a person who is hyperventilating is to breathe into a paper bag. This is no longer recommended, unless your doctor tells you to do so. Hyperventilation causes your body to expel too much carbon dioxide and that can change the pH level in the blood and cause metabolic problems. Since hyperventilation is mostly a psychological problem than a physiological problem, the best treatment is to is to stay calm and practice breathing slowly and not too deeply.
They take in oxygen, and expel Carbon dioxide as a waste product.
You spontaneously grow gills and then that works.
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.
Spiracles are the mechanism through which butterflies take in oxygen and expel carbon dioxide
the answer is a vein
The roots take in water and food - the leaves expel carbon dioxide.
All animals expel carbon dioxide from their lungs during respiration. This gas is a byproduct of the metabolic processes happening within their cells and needs to be removed from the body to prevent buildup.
Plants expel oxygen as a byproduct of photosynthesis. This process takes carbon dioxide and breaks it into carbon and oxygen.
Hyenas, like all mammals, breathe in oxygen from the air and release carbon dioxide as a waste product of respiration. They have lungs that extract oxygen from inhaled air and expel carbon dioxide when they exhale.
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)
