Introduction
Blood donation is a vital part of medical aid. Although there are artificial substitutes for blood, they will hardly ever be as effective as natural blood in cases when the blood transfusion is needed. In contrast to the blood, they lack plenty of natural substances, which are crucial for metabolism.
Main Body
Blood donation is a voluntary act aimed at the organization and supply of blood for medical and scientific purposes. The donors are the individuals who donate their blood and its integral parts. The blood donated by the volunteers is often divided into its components because some patients need only plasma, red cells, or some other components. Usually, the donation takes about 8-10 minutes but certain types can take up to two hours (Why donate blood? 2014).
It goes without saying that blood donation is an important part of medicine as almost every third individual on the planet needs the transfusion of blood once in his or her life. The rare blood groups represent especially bright evidence of the importance of voluntary blood donation. Sometimes, the relatives or friends become the donors for the patient. However, if the person who needs the transfusion has the rare blood group and Rhesus factor and none of the relatives has the same, the doctors use the blood donated and stored by the volunteers. Thus, voluntary blood donation can save the lives of people. The patients with leucosis need the transfusion every day and they will die without the supply of the donated blood.
Conclusion
There are also benefits from donating blood for donors themselves as it reduces the risk of heart attack and other cardiovascular diseases. Besides, it stimulates the circulation of blood and makes the skin and hair healthier.
