Answers
Answer:
i think the answer is thrombocytes and blood platelets
Answer:
Platelets
Explanation:
When one gets a cut, the underlying blood vessels get ruptured and start losing blood. When that happens, the first thing the vessel does is that it constricts itself. After that, tiny little fragments of cytoplasm (circulating within the blood) on reaching the rupture site get attached to the ruptured area, this is called platelet aggregation. These platelets then release signals calling for other platelets to come to the area and form a loose plug in a process called platelet activation.
A substance called Thrombokinase is then released, which acts like an enzyme to activate a substance called pro thrombin into Thrombin . The resulting Thrombin then converts a substance called fibrinogen, which is found in the blood, into fibrin strands which are insoluble in blood. These strands form a work of fibers in which blood cells get caught, hence resulting in the mostly red colored layer. New skin forms under the the red layer, which is eventually peeled off, this is, however, assuming that the injury at hand is an external one
