10 Uses of Oxygen
In cells, oxygen is needed for aerobic respiration, which allows for the extraction of energy from ingested foods. Thus supplemental oxygen at home and in hospitals is vital for those with breathing disorders such as emphysema.
Compressed oxygen tanks are used by mountaineers at high elevations to counteract the decreased O2 pressure at these altitudes.
Supplemental oxygen is needed for surgical patients intentionally rendered paralyzed for medical procedures, in which "heart-lung machines" keep their vital functions going.
Oxygen can be used as a sterilizing agent to kill certain anaerobic bacteria that are killed by sufficient exposure to the gas
In liquid form, oxygen is used widely as an oxidizing agent for use in missiles and rockets, where it reacts with liquid hydrogen to produce the terrific thrust needed for take-off. Astronaut spacesuits include a nearly pure form of oxygen.
Answer:
1. Oxygen is essential for respiration because the body uses it to 'burn' food molecules.
2. Animals take in oxygen when inhaling and give off carbon dioxide when exhaling.
3. Oxygen makes up almost 21% of the total gases in air, with most of the remaining gas being physiologically inert nitrogen.
4.Oxygen is the key for generating energy in cellular respiration.
5. Oxygen (O2) is one of the most important elements required to sustain life.
