The Element Oxygen has a chemical symbol O and atomic number 8. Oxygen was produced by numerous chemists prior to discovery in 1774, but each chemist failed to record it as an element. The main people are British clergyman Joseph Priestley, Swedish pharmacist Carl Wilhelm Scheele and French chemist Antoine Laurent Lavoisier all independently discovered oxygen. But Priestley usually gets the credit for the discovery. The name oxygen was first used by Lavoisier in 1777.
Oxygen plays an essential role in the lives of humans and other living organism. As well as being important for health and medical treatments it also helps us burn fuels, teat waters and even protect us from dangerous UV light thank to the ozone layer. Oxygen therapy is used as a common medical treatment. You may have seen

It is almost the most abundant element in the human body. Oxygen represents about half of the world's mass outside, 66% of the human's mass body and nine tenths of the mass of water. A lot of oxygen can be removed from condensed air through a procedure known as fragmentary refining. Oxygen can likewise be delivered through the electrolysis of water or by warming potassium chlorate. A reduction in the measure of oxygen per unit volume of air results in a deficient measure of oxygen entering the circulatory system. The body responds to this condition quickly. This shortage in oxygen is called Hypoxia. At the point when the body recaptures its ordinary oxygen supply, one may recuperate from hypoxia. A complete absence of oxygen, which brings about changeless physical harm or passing, is called Anoxia.
The element oxygen atomic weight is 15.999 and it is classified as a gas and nonmetal. It has the density of 1.429g/L and the melting pint of -218.79 degree Celsius and -361.82 degree Fahrenheit. It also has the boiling point of -182.95 degree Celsius and -297.31 degree
Oxygen, O2, is a kind of gas. A lot of the air we breathe as human beings is oxygen. Which is good since we need oxygen to stay alive. Oxygen is also a primary element in fire. Fire is a chemical process. Three elements are needed for this process: oxygen, heat and fuel. Without one of those
There is a small amount of carbon dioxide and more oxygen in the body because of gases exchange this is where oxygen form the lungs is transferred in to the blood and carried to the heart and when carbon dioxide is carried in to the lungs forms the blood and is exacted outwards by breathing. Mitochondria also need oxygen to create carbon dioxide for the body so the gas exchange can happen again. Outside the body there is a smaller amount of oxygen but it is still higher than CO2.
Once oxygen is deposited into the bloodstream by the lungs, the body must also increase your heart rate to deliver oxygen to the cells to once again maintain homeostasis. The increase in
1. Lungs depend on the oxygen that is derived from water in order to keep the cells alive in our body.
Hypoxia is simply a lack of oxygen at the tissue level of the body due to a decreased partial pressure of oxygen in the inspired air. Hypoxia is serious, because it may lead to death.(2) There are four stages of hypoxia.(1) The amount of time spent in any one of these four stages may vary, and each patient and provider is likely to respond differently to the same conditions.(1) The four stage of hypoxia are Asymptomatic, Compensatory, Deterioration, and Criticial.
Oxygen is one of the reactants necessary for respiration therefore it is essential for all living organisms. Oxygen is produced through the process of photosynthesis where energy from the sun is converted into chemical energy in the form of glucose.
The respiratory system is a complex organ structure of the human body anatomy, and the primary purpose of this system is to supply the blood with oxygen in order for the blood vessels to carry the precious gaseous element to all parts of the body to accomplish cell respiration. The respiratory system completes this important function of breathing throughout inspiration. In the breathing process inhaling oxygen is essential for cells to metabolize nutrients and carry out some other tasks, but it must occur simultaneously with exhaling when the carbon dioxide is excreted, this exchange of gases is the respiratory system's means of getting oxygen to the blood (McGowan, Jefferies & Turley, 2004).
After all of that the oxygen enters our bloodstream by diffusing through the membranes of the lungs and then into the blood vessels. This is then passed onto another system which is The Circulatory System; this system then transports the oxygen to all of the cells in the body and picks up any waste products on the way.
In 1787, an unusual rock had come across the work of Dr. Adair Crawford when investigating witherite, a mineral in Strontian, Scotland ("Strontium | Periodic Table." Royal Society of Chemistry). The discoverer of the element was testing the results of witherite and hydrochloric acid. When Dr. Crawford mixed witherite with hydrochloric acid he did not get the results he expected. He assumed that his sample of witherite was contaminated with an unknown mineral, a mineral he named strontianite ("The Element Strontium." It's Elemental). The discovery by Dr. Adair Crawford was the start of strontianite, but it was not the end of research on this element. Although Dr. Crawford technically discovered strontianite, he did not prove that it was a new element. In 1791, Thomas Charles Hope, continued the investigation of strontianite ("Strontium | Periodic Table." Royal Society of Chemistry). Through his investigation, Hope proved that strontianite was a new element. Finally the element, now known as Strontium, was isolated. Strontium was first isolated by Sir Humphry Davy, an English chemist, in 1808 through the electrolysis of a mixture of strontium chloride and mercuric oxide ("The Element Strontium." It's
Chemical equilibrium is a dynamic state where the rate of the reverse reaction is equal to the rate of the forward reaction. The chemical reaction is still occurring however the rate of reverse reaction is matching the rate of forward reaction hence the concentration of reactants (〖Hb〗_((aq) ) + O_(2 (g))) and products (HbO_2) no longer change, resulting in an equilibrium. (b) Which direction will equilibrium shift if the O_(2 ) concentration is increased?
the cells of the body receive oxygen and transport it around the body and expel the CO2.
The pure oxygen gives the user a lot easier time breathing and allows there body to work less to take in oxygen. The amount of intake of the pure oxygen is prescribed by a doctor and should not be tampered with, or the user might succumb to oxygen poising. The pure oxygen is only a temporary solution as the user’s lungs will eventually become so weak on their own the amount of pure oxygen will not be enough to keep them alive. After a patient’s lung capacity shrinks to where the pure oxygen is not enough they have to go get there blood and organs oxygenated. If the oxygenation of the body goes well they will have to repeat the process for the rest of their lives until the respiratory failure kills
Joseph Priestley was born and raised in England before immigrating to Pennsylvania in his later life. Priestley lived in the 18th century and contributed much to the fields of chemistry and biology. Priestley is considered important for many reasons, one of the main reasons being because of his discovery of oxygen. Priestley also discovered Nitrous oxide in 1772. An important discovery in the field of biology, was Priestleys' documentation of photosynthesis.
Oxygen is required by the cells to carry out respiration, this provides the energy in the form of adenosine-triphosphate (ATP) which is a molecule required for muscular contraction. As exercise takes place, oxygen is used
Oxygen is a part of the air and it is responsible for aerobic respiration in humans, animals and some microorganisms to produce energy and to function. Air also contains carbon dioxide, and it is a crucial part of photosynthesis in primary producers, such as plants, for the production of chemical energy (Reference, 2017).
