As a platelet plug forms, platelets release

Question

Quizplus · Accepted Answer

Platelets release serotonin during the formation of a platelet plug. This helps to enhance vasoconstriction, reducing blood flow to the site of injury and minimizing blood loss. Platelets also release other factors such as ADP and thromboxane A2 which help to recruit and activate additional platelets, leading to the formation of a stable plug at the site of injury. However, collagen and fibrin are components of the extracellular matrix and are not released by platelets. Creatine is a molecule involved in energy metabolism and is not directly related to platelet function.
