Answer 2

Answer:

1. Blood is a body fluid in humans and other animals that delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away from those same cells. In vertebrates, it is composed of blood cells suspended in blood plasma.
2. A universal blood donor is someone whose blood type is O negative. Blood type is a designation of two sets of proteins (called antigens) on the outside of red blood cells. One antigen type is the A, B, O type and the other is the Rh type (either positive or negative).
3. In transfusions of packed red blood cells, individuals with type O Rh D negative blood are often called universal donors. Those with type AB Rh D positive blood are called universal recipients. The antibodies will attack the antigens on any other blood type.
