Positive feedback

When a blood vessel is damaged, platelets attach and recruit more platelets to the area. These new platelets recruit even more, quickly increasing the number of platelets until the damage is sealed with a blood clot. This amplification is an example of.

Positive feedback.

Thermoreceptors detect body temp. and send impulses to the brain for analysis. If body temp. is low, the brain will signal skeletal muscles to perform brief, repeated contractions to help generate heat. In this example, what is the effector?

Skeletal muscles
