Platelets are responsible for ____
A
carrying blood clotting materials
B

C

D
carrying macrophages
Explanation: 

Detailed explanation-1: -Platelets are tiny blood cells that help your body form clots to stop bleeding. If one of your blood vessels gets damaged, it sends out signals to the platelets. The platelets then rush to the site of damage and form a plug (clot) to fix the damage.

Detailed explanation-2: -Platelets help prevent bleeding If a blood vessel is damaged, the body sends signals to platelets which cause them to travel to the injured area. Once the platelets arrive at the site, they clump together to form a clot that helps stop bleeding.

Detailed explanation-3: -The main job of platelets, or thrombocytes, is blood clotting. Platelets are much smaller in size than the other blood cells. They group together to form clumps, or a plug, in the hole of a vessel to stop bleeding.

Detailed explanation-4: -Platelets (a type of blood cell) and proteins in your plasma (the liquid part of blood) work together to stop the bleeding by forming a clot over the injury.

Detailed explanation-5: -Platelets help blood to clot Platelets are irregularly shaped fragments of cells that circulate in the blood until they are either activated to form a blood clot or are removed by the spleen. Thrombocytopenia is a condition of low levels of platelets and carries an increased risk of bleeding.
