This physiological process is responsible for bringing oxygen to and removing carbon dioxide from the lungs. Mixed venous blood carries carbon dioxide into the lungs and takes up alveolar oxygen.

We need to get oxygen from the air into the blood, and we need to remove waste carbon dioxide from the blood into the air. Moving gases like this is called gas exchange. The alveoli are adapted to ...

IN a study of the respiration of soils at temperatures ranging from 10° to 70°C, it was found that oxygen uptake and carbon dioxide evolution increased with increasing temperature above 50° C. 1.

A look at hypercapnia, also called hypercarbia, which is when a person has too much carbon dioxide in their blood. Included is detail on symptoms, risk factors, and treatment.

"Gas exchange is the transit of oxygen into the bloodstream, and carbon dioxide out." It can leave you with low oxygen, high carbon dioxide, or both.

A new study suggests that a small fraction of marine microorganisms are responsible for most of the consumption of oxygen and release of carbon dioxide in the ocean. This surprising discovery came ...

A Dec. 29, 2022, Facebook post (direct link, archive link) features a photosynthesis diagram, with a plant using light and carbon dioxide to produce oxygen and carbohydrates. "Remember science ...
