BLOOD

Here, we will now learn about water as a blood plasma component and details about it’s functions-

1. Solvent:-We have to understand an important fact that human body is comprised of about 70% of water hence, water acts as a solvent for all the other components of blood. The solutes like electrolytes can stay in their ionic forms only because of the presence of water. The gases are also dissolved.
2. Transporter:- All the components in blood cannot move by themselves therefore water helps all the other components to reach their destinations. This prevents material built-up in blood vessels and also blocking of veins and arteries.  Most importantly all the other components of blood are suspended.
3. Buffer:- The most important part is pH of blood (7.4) which is to be maintained. A maintained pH gives a perfect environment for the other components like proteins. Also a change in the pH can signal some kind of disease e.g. lesser pH than 7.4 is often seen in diabetes patients this condition is called acidosis and more pH in some diseases would be called alkalosis.
4. Osmotic pressure:- Water along with plasma proteins in particular albumin work to balance the osmotic pressure of blood in the blood vessels. As proteins are tightly restricted to the vessels rather than the ions like Na+ which move rapidly in between the vessels and interstitial fluid.
5. Thermoregulation:- The temperature regulation or as we say sweating, here, this water plays a major role in this with the help of hormones and salts present in the blood.
