Humans cannot extract enough oxygen from water to breathe normally under the surface, despite a social media post that claims to show this.

Researchers have created a paint containing living cyanobacteria that produces oxygen and can capture carbon dioxide. The bacteria’s ability to withstand extreme environments means this novel ...

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.

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 ...

Hypercapnia, also called hypercarbia, arises from having too much carbon dioxide in the blood. It typically happens with hypoxia, which is when there is not enough oxygen in the body.

Carbon dioxide is essential to photosynthesis, but plants and other natural processes only absorb about half of the CO2 emitted yearly.

For one, oxygen in the atmosphere was 40% to 50% higher than it is today. Despite the differences between past and present, the magnitude of the rises in carbon dioxide levels are similar.

Respiratory failure is a serious condition where the body doesn't get enough oxygen. Learn about the types, causes, symptoms, and treatments of acute and chronic respiratory failure.

As blood passes through the gas exchange region in the pulmonary capillary, carbon dioxide will rapidly diffuse from the blood into the alveoli, but the blood carbon dioxide will be constantly ...

Carbon dioxide is being converted into oxygen on Mars thanks to an invention undergoing testing that could lead to the colonization of the red planet. Day and night across the seasons, a lunchbox ...

Gas exchange in the lungs 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.

Yet the new study reveals that many proposed marine carbon dioxide removal (mCDR) methods—especially those based on biological processes—could in fact intensify oxygen loss in the ocean.
