Chemical Reactions Using Water

Water is the most important element in human life.

Water is one of the most important aspects of the human body and accounts for the majority of the body's composition. Water is highly important because of the large number of chemical reactions in which it plays a role. As a result, not drinking enough water can cause a number of health problems.

Significance

Every chemical reaction that occurs in the human body occurs through water. All cells in the human body are soaked in water. Nutrients and oxygen are transported throughout the body using water and individual cells need water to bring the nutrients and oxygen into them. Water is used to cool the body down through the action of perspiration. Water lubricates joints and internal organs, such as the eyeballs.

Digestion

Water is needed for most stages of digestion. The saliva that begins the process of digestion is partially made out of water, mixed with other enzymes. Water is used to ensure that the food easily slides down the esophagus. The digestive enzymes found in the stomach are also partially made out of water.

Hydrolysis

Water is needed to engage in hydrolysis. During the process of hydrolysis, water is split into ions that react with other substances such as sugar. This is an important part of cellular respiration.

Waste Formation

Water performs the fundamental function of breaking down molecules in the body, which is necessary for creating new molecules and generating energy. Waste products react are dissolved in water, which turns the waste products into urine. The urine is then evacuated from the body through the bladder.

Electrolytes

Electrolytes are chemicals that are found within fluids in the body, such as sodium chloride and potassium. Sodium chloride and potassium are the two chemicals that are most needed for nerves to send electrical signals. A lack of water leads to electrolyte imbalances, which can have a negative effect on nerve function.
