Red-cell antigens that determine blood-transfusion compatibility.
O-negative red cells = universal donor; AB-positive = universal recipient.
Coagulation Cascade
The chain of clotting factors that forms a stable fibrin clot.
Erythropoiesis
How the marrow turns a stem cell into a red blood cell, what it needs to do it, and what tells it to speed up.
Platelets: Structure and Function
The smallest blood cells, really cell fragments, that plug damaged vessels and start the clotting process to stop bleeding.
Haemoglobin: Structure and Types
The iron-containing protein in red cells that carries oxygen, built from four globin chains each holding a haem group with one iron atom.
Haemostasis and Coagulation
How the body stops bleeding from a damaged vessel, through the actions of vessels, platelets and clotting proteins.
