Write a note on blood donation.
Sometimes when we get seriously wounded and lose a lot of blood, this lost blood is replaced by the blood taken from another person. But we cannot just take blood from any person. The characteristics of the blood need to be studied before. The process of the transfer of blood from one person to another is called blood transfusion. The blood is provided by the blood bank to the people who are in need. Blood banks obtain blood from the healthy volunteers and supply it to the patients in need of it. If the blood that has been collected is not to be used immediately, it is stored in blood banks (under the specific required conditions) for some days. This act of donating blood by the volunteer healthy person to the patients is known as blood donation. A healthy person can donate blood 3-4 times in a year. The person who donates blood is termed as donor and the person who receives it is termed as receiver.
