What is the primary role of platelets in the circulatory system?

Carry oxygen
Fight infection
Form blood clots
Transport nutrients

The correct answer is: Carry oxygen

Platelets' primary role in the circulatory system is not to carry oxygen, fight infection, or transport nutrients. Platelets are actually responsible for forming blood clots. When there is a cut or injury, platelets rush to the site to help stop the bleeding by forming a clot. This clotting process is crucial for preventing excessive blood loss and promoting wound healing.
