Question

Create a concept map for the composition of blood. Include:

• What is found in the major layers visible when you spin whole blood in a centrifuge?
• Include the characteristics and functions of the specific types of blood cells covered in the Material Review.
• Include details on the ABO and Rh blood type systems - what is found on the RBC for each type, what is found in the bloodstream for each type, and who can receive each type of blood?

Answer 1

Hello,

Blood is a type of connective tissue and it is consist of-FLuid matrix,formed elements and plasma.Plasma make up 55%of the blood,it is basically a viscuous,straw colored fluid.Formed elements are erythrocytes,leucocytes and platelets.

When we centrifuge the blood the major visible layer is of serum which is plasma without fibrinogens(clotting factors).

In ABO blood grouping certain types of antigens are present or absent on the RBC.Incindiviuals with A blood group A antigen is present on their RBC and have anti B antibodies in their blood stream.In individuals with B blood group,B antigen is present on the RBC and have anti A antibodies.Person with AB blood group has both A and B antigen on the RBC and has no antibodies.Person with O blood group has no antigen on the RBCs and has anti A and anti B antibodies.Rh antigen is also present or absent in certain individuals depending on which they are Rh+ or Rh-.AB+ people are universal receiver as they would have no antibodies against any antigen of RBCs in their blood.

Hope this helps.
