Question
In initiating hemostasis, what typically activates platelets?Multiple choice question.reticulocyte activating factorexposed collagenlow oxygen concentrations
Solution
The activation of platelets in initiating hemostasis is typically triggered by exposed collagen. When a blood vessel is injured, the endothelial lining is disrupted and the underlying collagen is exposed. This exposure of collagen triggers the platelets to adhere to the site of injury, become activated, and initiate the process of hemostasis to prevent excessive bleeding. Therefore, the correct answer is "exposed collagen".
