What is blood transfusion? ?

A blood transfusion is a medical procedure in which blood is transferred from one person (donor) to another person (recipient). This is done to replace blood that has been lost due to surgery, injury, or illness, or to treat certain medical conditions such as anemia or clotting disorders. Blood transfusions can be life-saving in emergency situations and are commonly used in hospitals and healthcare settings.
