Study Notes

Blood Components

Platelets: Cell fragments, no nucleus, produced in bone marrow, function in clotting.
Plasma: Makes up 55% of blood, mostly water, contains proteins like clotting proteins and antibodies, transports hormones and urea.
Lymphocytes: Produce antibodies.

Blood Grouping

Blood types are grouped based on the presence or absence of antigens on red blood cells (RBCs).
Antigens are molecules that trigger an antibody response.
Blood types include O, A, B, and AB.
Receiving the wrong blood type during a transfusion can cause antibodies to attack the foreign blood, leading to clumping.
