The Relationship Between Work Rate And Oxygen Uptake During Incremental Submaximal Exercise Introduction Oxygen uptake () describes the rate at which oxygen is utilized by tissues (Burton et al‚ 2004). is determined by heart rate (heart beats each minute)‚ stroke volume (the volume of blood pumped from one ventricle each beat) and arteriovenous oxygen difference (difference in blood-oxygen content between arterial and venous blood). Oxygen is needed for respiration‚ the chemical process that

Water is a chemical compound with the chemical formula H2O. A water molecule contains one oxygen and two hydrogen atoms connected by covalent bonds. Water is a liquid at standard ambient temperature and pressure‚ but it often co-exists on Earth with its solid state‚ ice‚ and gaseous state (water vapor or steam). Water also exists in a liquid crystal state near hydrophilic surfaces. Water is considered a purifier in most religions. Major faiths that incorporate ritual washing (ablution) include Christianity

is a low water temperature a fish slows down and so do its metabolic activities and when water temperatures are high‚ fish speed up and their metabolic processes increase as well. Proteins and enzymes are also affected by temperature changes. Oxygen is essential for the production of ATP from nutrients in cells; consequently oxygen must be delivered to a cell in sufficient amounts. Within fish‚ the counter-current exchange system allows for the efficient extraction of oxygen from the water by the gills

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

fresh water is also becoming a scarcity. The limited availability of fresh water and its unequal distribution make water pollution a matter of great concern. Water pollution is generally localized and confined‚ making it more severe. The pollutants undergo many reactions and can become hazardous. 70 % of India’s fresh water is polluted‚ including several high altitude lakes. While water pollution is easier to study and manage‚ its control is highly complex and very costly. Water pollution
