blood clotting
- plasmid, blood cells and platelets flow through
- platelets come in contacts with tissue collagen fibres breaking down releasing
- 1) serotonin- contraction of
blood vessel restricting blood
flow to damaged area
- 2) thromboplastin- catalyses conversion of
prothrombin to thrombin with right
concentration of calcium ions
- thrombin convert fibrinogen into fibrin forming a mesh of fibres which comes in contact with more blood cells and platelets forming a clot
- protein in plasmid structure tightens and toughens the clot
