Oxygen content in the body refers to the amount of oxygen present in the blood. This is measured as arterial oxygen saturation (SaO2) or oxygen partial pressure (PaO2). Adequate oxygen content is vital for proper functioning of organs and tissues in the body.
The atmosphere is 79.9% oxygen.
The approximate oxygen content of air is around 21%.
it was first tested in April 1973.
Take a test tube and put inside it a glowing splint. If the splint relights, the oxygen is present. If not, there is no oxygen.
no
The oxygen content of air is approximately 21%. Nitrogen is the largest component of air as it takes up 78% of the atmosphere.
Oxygen content is highest in the troposphere, which is the lowest layer of Earth's atmosphere. Approximately 20% of the troposphere's gas composition is oxygen, making it the layer where oxygen is most abundant.
The layer of the atmosphere with the highest oxygen content is the troposphere, the lowest layer where most weather events occur. About 20.9% of the air in the troposphere is composed of oxygen.
