When platelets attach to collagen threads in an injured vessel the platelets swell, form extensions and then stick together. as a result of these steps what structure is formed?
When platelets stick to each other and to the blood
vessel they form a plug in the hole of the vessel. This process is called platelet aggregation.
Before the plug forms, a platelet will stick to the blood vessel (adhesion), change its shape
and signal other platelets to come help (activation and secretion). Then they
stick to each other (aggregation).
