The difference between donating plasma and donating blood

There is a big difference between donating plasma and donating blood. The so-called plasma is not blood. The blood needs to be anticoagulated first, and then the plasma in the blood is collected, and all the components of red blood cells, white blood cells and platelets are transfused back to the blood donor. This will have some impact on the body. The impact of donating blood on the body will be slightly smaller.
