HYPOXIA Introduction 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. Diseases of the blood‚ the heart and circulation‚ and the lungs may all produce some form of hypoxia. There are four types of hypoxia: (1) the hypoxic type‚ in which the oxygen pressure in the blood going to the tissues is too low to saturate the haemoglobin; (2) the anaemic type‚ in which

IMPORTANCE OF FORESTS Introduction Trees are mankind lifeline. If they are destroyed‚ there is no way that human beings can survive. From the oxygen that we breathe in‚ the food that we eat‚ to the clothes we wear‚ we owe it all to the trees. Not only this‚ trees act as purifiers of air and receptacles of our waste products. Trees have great economic value too. We get fuel‚ fodder‚ timber‚ medicines and numerous other valuable products from the trees. It is‚ therefore‚ not surprising that trees

for yoga practitioners to help and prepare them in theirMeditation process. In our respiration process‚ we breathe in or inhale oxygen into our body‚ going through our body systems in a form of energy to charge our different body parts. Then we exhale carbon dioxide and take away all toxic wastes from our body. Through the practice of Pranayama‚ the balance of oxygen and carbon dioxide is attained. Absorbing prana through breath control links our body‚ mind‚ and spirit. But life is full of stress

Hyperbaric oxygen therapy "is a well-established treatment for decompression sickness‚ a hazard of scuba diving" (Hyperbaric oxygen therapy‚ 2014). It involves breathing pure oxygen in a pressurized room or tube (Hyperbaric oxygen therapy‚ 2014). In a hyperbaric chamber the air pressure is increased by three times that of normal air pressure which allows the lungs to gather more oxygen (Hyperbaric oxygen therapy‚ 2014). The increase in oxygen within the body allows the body to better fight off bacteria

In the article‚ “Oceans Are Losing Oxygen—and Becoming More Hostile to Life” by Craig Welch‚ climate change is affecting the lives of all kinds of sea creatures. This article explains how climate change‚ and the warming of ocean water‚ has began taking oxygen out of the water. This means that many fish species have shrunk because of this loss of oxygen. The warmer water speeds up the metabolism of these fish‚ which makes them breathe in more of the oxygen. A couple of scientists from the University

The tires absorb moisture from roads while in motion. It can also pull carbon dioxide out of the air to fuel the moss’ photosynthesis which has clean oxygen as its byproduct. Absorbing 4‚000 tons of C02 a year Goodyear’s estimate is that the Oxygene‚ if all the 2.5 million vehicles in Paris switch to the brand‚ could produce 3‚000 tons of oxygen and absorb more than 4‚000 tons of carbon dioxide annually. The tire‚ however‚ goes beyond cleaning the air.
