A
Capillaries
B
Platelets
C
Plasma
D
Vena cava
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 (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-3: -When a blood vessel is damaged, blood cells and plasma ooze into surrounding tissue. Platelets immediately stick to the edges of the cut and release chemicals that attract more platelets. Eventually, a platelet plug is formed, and the outside bleeding stops.

Detailed explanation-4: -Platelets help prevent bleeding Their primary function is to prevent and stop 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.
