Describe and explain the roles of water in living organisms and as an environment for the organisms

Without water there would be no life on Earth; this is why water is the most important biochemical of all.

  In “Human Biology” by J.M Orten and O.W. Nevhans, it is suggested that 70% of all body weight is water, most of which is found in three major compartments: 70% intracellular fluid, 20% interstitial fluid (lymph) and 7% blood plasma, and only 3% in other compartments. By volume, nearly a half of each of our organs consist of water; amounting to approximately 10 gallons of water, of which most is in our cells.

  Water is crucial for cells to function healthily and for all chemical reactions and transport processes to occur. Water is responsible for maintaining cell structure, aiding metabolism and helping the circulation of blood and bodily fluids; water is also responsible for removing bodily waste through excretion.

  Water is effective in neutralising the blood, for example, if the blood is too acidic it is likely the body will suffer from high pressure, this is when water is required to control the acid level of the blood.

  Another important process involving water is homeostasis. This is when the body maintains a constant internal environment, including, the regulation of glucose concentration, metabolic wastes, temperature and pH. Water helps to keep the body temperature constant when: the eaten food inside the body is turned into heat energy, this is then turned into action energy for all the daily ...
