Question

We give out Carbon dioxide when we exhale.

Explain in a short paragraph.

Answer 1

When CO2 is breathed into the lungs, it dissolves in the water there, diffuses across the alveolar-capillary membrane, and enters the bloodstream. As it combines with water, it forms carbonic acid, making the blood acidic. So CO2 in the bloodstream lowers the blood pH.

Answer 2

Answer:

After we take a breath, the lungs transfer oxygen to our blood to be transported all over our bodies to help our cells work. ... This is another reason you breathe heavier when exercising — you produce carbon dioxide faster and need to get it out of your body to make room for more oxygen.
