In response to injury, cell fragments called platelets get activated to induce clotting. Activated platelets release factors that can in turn bind to specific membrane receptors on nearby cells. What type of signaling would this be considered

Answers

Answer:

Activated platelets express negative phospholipids on the exterior leaflet of their cell membrane, release vasoactive compounds, release cytokines, and release growth factors.

When an injury causes a blood vessel wall to break, platelets are activated. They change shape from round to spiny, stick to the broken vessel wall and each other, and begin to plug the break. They also interact with other blood proteins to form fibrin.

Platelets contribute their hemostatic capacity via adhesion, activation and aggregation, which are triggered upon tissue injury.
