Bleeding

Which component of blood is responsible for helping to stop bleeding?

• platelets

• red blood cells

• white blood cells

• plasma

When you get cut, your skin cells release hormones that signal platelets to come and stop the bleeding. Platelets then release more hormones that signal even more platelets to help stop bleeding. The hormone signals continue until the cut is closed.

• Positive Feedback Response

• Negative Feedback Loop
