Which of the following helps in the clotting of blood?
Answer Details
Platelets are the blood cells that help in the clotting of blood. When there is an injury or damage to a blood vessel, platelets rush to the site of injury and form a plug to stop the bleeding.
Platelets are tiny cell fragments that are produced in the bone marrow and circulate in the blood. They contain special proteins and enzymes that help them to stick together and form a clot.
The clotting process begins when platelets are activated by a signal from damaged tissue or blood vessel. Once activated, the platelets stick together to form a plug that helps to stop bleeding. The clotting process is also aided by a number of clotting factors that are present in the plasma, the liquid part of the blood.
Red blood cells carry oxygen to the body's tissues, while white blood cells help to fight infections. However, neither of these cell types are directly involved in the clotting process.
In summary, platelets are the blood cells that help in the clotting of blood, by forming a plug at the site of injury or damage to a blood vessel.
