Late in intrauterine life and after birth, RBCs are synthesized in liver and spleen . 7. Damage to endothelium allows RBCs to bind to exposed collagen . Collagens attract RBCs ,which stick to it within minutes after damage . 8. Clotting can be prevented by Ca+2 chelators (e.g. sodium citrate or EDTA) 9. Amplitude of AP is the same regardless of whether the depolarizing event was weak or strong. 10. Impulses are able to cross the synapse to another nerve by neurotransmitter which is released from a nerve’s axon terminal 11. Repolarization phase of AP is due to rapid entery of Na ions. 12.
