Physiological Properties of Water

Introduction:

Water constitutes around 70% of the earth’s surface being the most abundant compound that is available on the planet. It is often referred to as a universal solvent as many substances tend to dissolve in water. In the figure below, we can see the molecular binding of water molecules.Water in our body plays a major role in performing various function which are important for day to day activities that carries inside the body. Physiological properties deals with the functioning of water inside the tissues and the organs.Let us discuss in brief.

The Physiological Properties of Water

• Water makes up most of the body's weight.
• It carries helps in transporting of substances inside body cells with the circulatory system.
• It helps in excretion. The waste materials present inside the body can be removed by filtration through kidneys. Water plays an important role in excreting out these toxic materials.
• It helps the cells to gain dissolved oxygen.
• It helps when the body gets dehydrated.
• Our skin contains water. During any disease, when the water content inside the body is affected, hormones like ADH, aldosterone helps in regulating the water content of the body.
• Water gets inside our body through stomach, intestinal canal, then it reaches the blood and the volume gets increased and which in fact raises the vessels of circulatory system. Water makes the blood dilute and hence the circulation becomes fast.
• It is excreted or expelled by skin, lungs, kidneys, and intestines.  Due to solvent action, it helps in dissolving  a variety of poisonous products of  tissues.
• It helps in urinary excretion where the waste material urea is excreted, which is formed by kidney.
• We should drink a lot of water that produces copious perspiration along with urinary excretion.
• It also helps in preventing constipation problems related to improper bowel movement.

Conclusion for the Physiological Properties of Water

From the discussion on the psychological properties of water, we conclude that water is an essential substance for life on the planet earth as it not only makes up 55-78% of the human body but also is very important source of life to plants and animals. We also came across the importance of water inside our body cells.
