What is the function of platelets Class 9?

The principal function of platelets is to prevent bleeding. Red blood cells are the most numerous blood cell, about 5,000,000 per microliter.

What are thrombocytes and what is their function?

How platelets are adapted to their function?

They contain proteins on their surface that allow them to stick to breaks in the blood vessel wall and also to stick to each other. They contain granules that can secrete other proteins required for creating a firm plug to seal blood vessel breaks.

What would cause increase in blood platelets?

Some of the causes of elevated platelet counts are spleen removal, infections, cancer and rheumatoid arthritis. According to the Mayo Clinic, spleen removal, or splenectomy, is associated with lifelong elevated platelet counts. The spleen helps remove excess platelets from the bloodstream.

What are the platelets responsible for?

Platelets, a vital component of blood, are primarily responsible for cessation of bleeding by forming blood clots. When removed from the blood stream and subjected to component manufacturing, platelets natural response is to form clots.
