Resource summary
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
