Question
What type of feedback loop is blood clotting?Group of answer choicesneutralnegativepresumptivepositive
Solution
Blood clotting is an example of a positive feedback loop.
Here's why:
-
In a positive feedback loop, the output of a system intensifies the response of the system. In other words, the effect of the response is amplified.
-
When a blood vessel is damaged, platelets start to adhere to the site of injury to block the bleeding. This is the initial response of the system.
-
These platelets release chemicals that attract more platelets to the site. This is the output of the system.
-
The arrival of more platelets leads to the formation of a blood clot, which further blocks the bleeding. This is an intensified response of the system.
-
Therefore, the process of blood clotting is a positive feedback loop because the response (formation of a blood clot) is amplified (more platelets are attracted to the site, leading to a larger clot).
