- When platelets come in contact with injured tissue
they change their characteristics. They:
|
| |
start to swell |
| |
assume irregular forms with numerous irradiating
processes |
| |
become sticky |
| |
secrete ADP |
| |
secrete thromboxane A |
| |
- Thromboxane A and ADP react with other platelets and
activate them. Thus a vicious cycle is initiated and a fairly loose
plug is formed.
