67. Before we had figured out the ABO and Rh blood type groups, we often transfused patients with just blood
plasma to reduce the chances of rejection and complications. However, note that there are many different
factors in the plasma component as well: dissolved food molecules, hormones, antibodies, etc. Why are we not
concerned about a male patient receiving a plasma donation from a female donor where there will be some
estrogens in the plasma? Is the amount of fats, glucose, and amino acids in the plasma of any importance?
