At rest, the average adult inhales around 20 percent oxygen in the air and exhales about 15 percent oxygen, according to HowStuffWorks. People inhale and exhale approximately 7 or 8 liters of air each minute or 11,000 liters per day.Know More
HowStuffWorks states that 5 percent of the volume of air is consumed each time a person inhales and is converted to carbon dioxide. Thus, a person uses around 550 liters of pure oxygen daily. Dr. Dawn A. Tamarkin of the Springfield Technical Community College explains that the normal amount of air breathed in and out at rest is called the tidal volume of air. The maximum amount of air a person can inhale and exhale is known as the vital capacity. A person normally does not use his entire vital capacity. When speaking or being active, a person takes in and lets out more air than the tidal volume.
The body only uses air when there is gas exchange, which occurs in the alveoli, notes Dr. Tamarkin. Upon inhaling, a person takes air into the respiratory system, and the air travels into the alveoli. Some air remains in the nasal cavity, trachea, bronchi and bronchioles to avoid creating a vacuum. The air stays in the respiratory passageways, and it cannot be used by the body.Learn More
Some biomass is formed when animals eat plants and, through the digestion and excretion process, turn it into biomass, and the rest is formed when microorganisms eat plant material, or the plants are consumed by fire. Either way, all biomass has a carbon base and is made of a blend of organic molecules that have hydrogen and also usually have oxygen, nitrogen and other atoms.Full Answer >
